I have an A.O. Smith SP1607-Z-1-MXBK (1 HP) motor that operates a water fall near the pool. The pump appears to be leaking near the bottom of the motor, probably a shaft seal. I see the UST1102 is a replacement for this. I am wondering if there is a more energy efficient replacement available.
Hello Bob, There is an Energy Efficient for the SP1607-Z-1-MXBK is the A.O. Smith 1 H.P Pool Motor Energy Efficient Round Flange - UCT1102.
94027110 is this motor designed to turn on and off for energy savings, automatically.
Hi, Ron. This motor will run continuously once power is supplied and turn off once power is cut off if controlled by an external controller.
Just replaced my magnum pump, came with ao smith 1 hp. Keeps shutting down after 3 minutes. where can I get schematics on this. Any thought.
Hi, Ron. It sounds like the motor may be overheating shutting off and then turning back on once it cools down. This can be caused if the motor was replaced with a less than equal THP, a bad impeller and or a faulty thermal overload.
Have century c4kzn143b1.ser#17814j2. What is direct replacement pump and seal kit. Pool is salt water
This model number does not cross reference on our site, google or A.O. Smith/Century's page. Please send us some images of the front pump housing model label and of the motor label to firstname.lastname@example.org.
Can i fully submerge the A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102? Is it fully water proof?
These motors can not be submerged.
Just installed a 1HP Century motor on my pool pump. The pump appears to be running hot I shut the pump off when my infrared gun said it was at 170. Installed new seals, check power it was 241v, installed new filter. How hot will this get and not damage the motor. Any ideas.
Hello Randy - One of the long time rules is to keep the bearing temperatures under 200°. There is a thermal overload protector which will shut the motor down at 256°. This would be the temperature of the winding, at the hottest point.
I have a century pump motor part # B228se, can I replace it with the century UST 1102,or can you tell me what the difference is between the 2 motors. Thanks Ken
Hi, Kenneth. You can use the UST1102 motor as a replacement for the B228SE. The difference between the two motors is the design and efficiency. The B228SE uses less energy than the UST1102 motor.

Hi, Duce. This Century UST1102 Motor is the replacement for the SP2607X10 Pump. This motor can be return if it's in new or unused condition within 30 days and comes with a 1 year manufacturer warranty. I would also recommend getting the Hayward Super Pump Tune Up Kit - GOKIT3 or GOKIT3SALT.

Need to replace a C48K2N143B1 (thermal shutdown) in a Hayward SP2507x10 housing. Is this the correct replacement, and what tune-up kit is needed, since I think it would be a good idea to overhaul all possible while disassembled.

Hi Larry, If you have the Hayward Max Flo XL SP2507X10 Housing then you will need the SPX2707Z1M 1 HP Replacement Motor and the Max Flo XL Shaft Seal. I would double check that you don't have the SP2607X10 Super Pump, if you do have the SP2607X10 then you will require this UST1102 1 HP Motor along with the Hayward Super Pump Shaft Seal.
I have a AO Smith C48K2N143 motor, SF 1.1, Frame 56J, 115/230V. What replacement motor is right? is there a more energy efficient motor I can use that will also fit? Also, what information do I need for a gasket kit.
Hi Paul, This UST1102 Motor is the direct replacement for your C48K2N143 motor. If you would like to go Energy Efficient then you can go with the UCT1102 1 HP Energy Efficient Replacement Motor which will save you roughly 20% on your operational costs. The most popular pump that this motor mounts to is the Hayward Super Pump and if you have that pump then you will need the Hayward Super Pump Seal Kit If this is not your pump then please send us a photo showing your complete pump including where the plumbing goes in and out of the pump. To send this photos simply reply to this email or send them to email@example.com
How about for a Hayward SP2807X10 Max Flo pump, Model C48K2N143B3? The one I bought from you is making a very loud, grinding sound. Thinking I just need to replace the motor and not the entire pump unit. It is a slat water chlorination system. Is that (the salt water) the problem?
Salt water making its way past the man shaft seal to the motor face can indeed cause the bearings to fail which is known to create the loud noise. If you purchased the motor within a year ago then it may be under warranty. We would just need a few images of the motor in order to run a warranty claim for you. Please call in or email us at firstname.lastname@example.org if you need assistance in beginning the warranty claim process.

I am ordering a replacement motor UST1102 for a salt water pool. What seals do I need? The parts are # SP2605-C and SP2600-E. Thank you kindly, Ted
Hi Ted, You have the Hayward Super Pump so you would require this Hayward Super Pump Salt Seal Kit
I'm replacing a motor on a Pentair Challenger pool pump. Original is a 3/4 hp 1.67 SF. Will a replacement with a 3/4 hp 1.65 SF be adequate? Seems like the .02 less on the SF is insignificant. Am I correct in my assumption and okay with purchasing motor at 1.65 SF? The pump is used solely to pump water to a water feature that is at a level above the pump, so adequate power is essential. Thank you!
Yes, so the B847 would be the correct motor replacement and the shaft seal is part number 5250-104.

I need to replace my AO Smith motor for a Hayward pump. The model # is C48K2N143B1, frame = 56j, SF = 1.1. Based on your Q/A section, it appears the replacement motor for this is UST1102. However, the description states it an "up rate" motor. I'm not sure what this means. Second, my current motor is a "round" flange, correct? This link from your website appears to be the correct motor, please confirm. Thank you, TJ
Hi, TJ. This is the correct replacement based on the info provided.

I have a Hayward pool pump model SP2607X10 and need to replace the pump motor, what motors will work? Please indicate all the A.O. Smith replacement models to include the energy efficient models . Can you indicate typical pay back on the energy efficient models and if wiring hook up is the same as the base replacement model. I also need to a seal kit and i think the one i require for salt is a Go Kit 3 is that correct? Thanks
Yes, the UST1102 is going to be the replacement. UCT1102 is the energy efficient replacement that uses 2 amps less while keeping the same horsepower so saving money on your energy bill. STS1102 is the dual speed replacement that will allow you to run it at high, 1HP, and low, 1/4HP, which has the potential to save you even more money. The real energy saver is going to be the ECM16CU which is the variable speed replacement. With the variable speed you will be able to adjust the RPM's to where it is going to be the most efficient for your system. The seal kit you want is the GOKIT3SALT.
I have model number C48AB45A01. What is the replacement pump for this model? Thank you.
Hi, Nancy. The USQ1102 motor would be the replacement motor that we have as a replacement for model # C48AB45A01.
I want to make sure I get the correct seal kit for A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102 could you please give me the part number
Hi, Joe. We will need to know the model number of the housing that the motor is mounted too in order to get you the correct seal kit.

I need two replacement motors for model K48L2N104 and I am unclear if this is the correct one. Can you tell me if I need the ST or the CT 1102? The one you offer has slightly different specs than what I am replacing. For example, the SF rating is 1.5 on the old motors as opposed to the one you offer which is 1.1. Also the max amp load is slightly lower on the old ones than the one you offer (14.6/7.3 vs..15.0/7.5). I also don't see K48L2N104 in the alternate parts list Please advise... Thanks
You can use either the CT1102 or the ST1102. The CT is the energy efficient model that pulls less amps. Both have an S.F. of 1.5.
I have a Hayward pool pump, model #C48K2N143B3, that needs a new motor. Please advise which motor I should buy as a replacement. Thank you.
The correct replacement motor for model #C48K2N143B3 is the A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102.
I have a pool motor installed from A.O. Smith Part # 164904-03 Serial # BZ07-20 it is a 3 phase motor and I need to replace with a 208v single phase motor. Can you give me a replacement part number for this?
Are you able to attach a picture of your complete pump and the motor label so I can better help you? The part number that you provided is not pulling anything up for me.
What would the appropriate replacement part be for the Hayward Super II PUMP MOTOR K48L2N105?
Good morning, You actually have a couple different options for replacement. You have an Energy efficient option. You can go Up rated or Full Rated. Based on Price I would recommend the A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102. You will also need to replace the shaft seal and some o-rings that you can get in Tune Up Kit Hayward Super II - GOKIT2
Is this the proper replacement for the Model #C48K2PA104A3?
Hi, Gary. The correct replacement motor for Model # C48K2PA104A3 would be the USQ1102 Motor.
Is this motor interchangeable with a model C48L2N134C2?
Hello Ben- The UST1102 A.O. Smith 1 HP Round Flange Up Rate Motor is not the correct replacement for your C48L2N134C2. The correct motor is the A.O. Smith 1 HP Full Rate Round Flange Motor - ST1102.
I plan on replacing my Hayward pump motor model #C48K2N143C1C with the A.O. Smith UST1102. Is there any other parts I need? Shaft seal, gasket O rings, etc..? The model number of my pump housing is SP2807X10. Thank you
The seal kit for the Hayward Max-Flo is the GOKIT1
I have to replace my C48J2N131B1 3/4 HP and was looking to up the HP as I of my 3 returns barely has any water output. The pump is coupled with a pccf-125 filter. Would this pump work with my current filter/chassis or am I stuck with the UST1072? What impeller/seal kit would I need?
Hi, JL. You provide you with the correct answer to your questions we will need the model of the pump, the Feet of Head of your pool and any other water features you have. The info you provided is for the motor and the filter. If you do not have the pump model number please provide photos of the pump housing.
This pump differs from mine in that yours does not indicate Rotation - mine says CCWPE. Also the Amperage is slightly higher. Yet they are both C48K2N143C1C. Why the differences?
Good Morning Pete, This motor is compatible with the C48K2N143C1C, But they are not identical. This motor is up-rated. That is why the amperage is higher. For the rotation you will have to view with back of the motor off to see which way the shaft is spinning. If there is anything else I can help you with. let me know.
I have a 1HP UST1102 motor and i'm look to down size to a 3/4 HP that will fit the same pump housing. What motors do you have that I can select from?
Can I replace C48K2N143C1C with this?
Yes, the UST1102 is the correct replacement motor.
Can I replace my US Motors model# K63CXEPY-4766 1HP motor with this motor?
The replacement motor for the K63CXEPY-4766 is the Motor 56j Thrd Full Ee 1hp (b654). The total HP on your current motor is 1.40 and the UST1102 is 1.10. The weight of the impeller, installed on motors will differ depending on the total horsepower. By decreasing the horsepower, the impeller will be to heavy, potentially causing the motor to fail. It is best recommended to replace your motor with the B654, doing so, this will allow you to use your existing impeller. Don't forget to replace the Pool Pump Shaft Seal.
Is this motor interchangeable with a Hayward super pump 1hp? Model C48K2N143B1
Hello Brian, the UST1102 motor is a replacement for C48K2N143B1.

Hi Richard. Yes, the UST1102 will replace C48K2N143B1 motor.
My pool motor finally blew- I have a Hayward Super II pump, MODEL# K48L2N104 , 1 HP, Frame 56J- about to completely disassemble to ensure flange is round- I also have 6 bolts that hold the impeller- is this the correct model to replace my motor with or will I have to also replace the impeller as well- I JUST rebuilt the entire impeller last summer- can't afford to do all over-of course it's an emergency- daughter decided she to have her college grad party Sept 24th!!!! I am in panic mode.......
Hello Melissa, from the number K48L2N104 it brought up ct1102 for your motor, but either motor would work for you. I would replace the pump seal, 5110-11 for the Super II pump.
C48J2N131B1 is 3/4 HP and was told A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102 would be the replacement. Difference in HP won't make a difference?????
Hi. The UST1072 is the correct replacement for the C48J2N131B1 motor, the difference in the HP will make a difference.
my Hayward north star pump has an ao smith motor model #usn1102 1 hp. can I replace the motor with a model #ust1102 1 hr?
Hello John, you need to make sure you are going with a motor that has the same output that you are getting from your current motor. If you go with a UST1102 your amps are running at 15.0/7.5 SF is 1.1 and HP at 1.1, you are actually going down from the motor your USN1102 motor. Your SF, HP, and AMPs would go down if you went with the UST1102.
I have a Hayward Star Clear Plus Filter with a A.O. Smith Corp motor model # C48AA35A01. Would this be the right motor to get to replace it and also please give me part number for the shaft seal?
Hello Risa, to replace C48AA35A01 motor it would be UST1102. To get your seal kit we would just need to know if you have Jacuzzi R series, HHP series, Jandy plus HP, Pentair Purex, or Hayward RS series.
Will this replace a Hayward SP1607Z1M and if so will i need anything else? Thanks
Hello Don, Yes that is the replacement motor, I would recommend for which pump you have to get a GOKIT which has your pump seal, oring, and gaskets needed for when you take apart your motor to replace it.

Hello, George. The EST1102 is still available to order. The comparable replacement is the A.O. Smith 1 HP Full Rate Round Flange Motor - ST1102. Don't forget to replace the Shaft Seal Assembly or Tune-Up Kit when replacing the motor. If you need assistance identifying the Shaft Seal or Tune-Up kit you may contact us at 1-877-372-6038 or email photos of the pump housing to email@example.com
IS THE A O SMITH POOL MOTOR # UST1102 THE REPLACEMENT FOR THE USQ1102. I WANT TO MAKE SURE IT WILL FIT THE OTHER EXISTING PARTS.
Hello John, You really want to stay with USQ1102 because your UST1102 is a cface rather than a square flange. Your frames would not match up. Stay with the one you currently have USQ1102.
Will this work for replacing a hayward power flo matrix motor? It is longer.. and my old one is only 1/2 hp
If you do move to a 1HP you will have to upgrade to a 1HP impeller. Also, you will want to know the flow rate of your filter. You don't want the increased horsepower to blow your filter.
I'm not sure what brand pool motor I have. The Motor Mod #C48K2N143C1C, serial #31012CH, 1 hsp, UST1102, type UAK RegalBeloit EPC. It looks like, from what I have found online that it is an A.O. Smith, is this correct? What is the best replacement motor for a 16X32 ing. pool? Thank you.
The correct replacement motor for model #C48K2N143C1C is the A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102.
I need to replace my Hayward Super Pump Motor (1 hp). Hayward Model # is C48K2N143B1. What motor would I need to purchase as a replacement and do I need to buy anything else? Does this motor come with replacement instructions? My current motor will not turn but the impeller does turn freely. Does the impeller come off because the picture does not show an impeller with the motor. Thanks
The UST1102 would be the correct replacement motor and the seal kit you'll want to get as well is part number GOKIT3.
will this motor replace my motor on a StaRite Pool System 3; Mod S7D75 Flow Rate 75GPM ? from a sunbleached / weathered label on the motor i see the mod # C48K2PA1C4A3
It's most likely going to be the USQ1102, but to be for sure I'll need to know the model of your Sta Rite pump, not the system 3 filter. If you're not sure you can attach some pictures of the entire pump and I can identify it for you.
I have a Hayward self priming super pump 1hp Model 48K2N143B1 Can't read the first digit of the number. Will this motor work? What else is needed for replacement
Wanetta, Yes, This will replace your existing 1HP Hayward Super Pump motor. We also recommend a tune up kit.
Can I use this pump to replace a CT1102 on a Hayward RS1000? If so, what is the running cost difference? Thanks
Hi Steeve, The UST1102 will not replace the CT1102 motor, but you can use the UST1152 motor as a replacement. The CT1102 will use less energy than the UST1152. The Hayward Super II Pump Tune Up Kit GOKIT2 or GOKIT2SALT is compatible with the RS1000 pump.
Where is this motor manufactured. If in a foreign country, are there any pool motors that are US made, and if so, by whom? how long should a pool motor last?
This motor is made in China. The motors have a 1 year warranty. There is no set time frame for a motor to last.
We installed this motor about a year ago. Everything worked great until this weekend. Suddenly breaker in basement is tripping. Pump is able to run for several hours before tripping. GCFI between pump and house is not being tripped, only the breaker in the house. What could be the issue? Motor is new, hoping it's not gone bad already. Thank you for any help you can provide
Hi Joe, Once the motor starts tripping the breaker it's time to replace the motor. You can try using some of the tip provided in our Pool Motor Troubleshooting blog to try to see if it can be resolved.

What other parts do I need when replacing the motor? Impeller? What else? Thanks.
When replacing a motor, we would recommend replacing the shaft seal and o-rings on your pump. You will need to identify which pump you have to locate a parts list and the corresponding replacement parts. We would also recommend inspecting your pump to determine if you may need to replace other parts due to damage or deterioration.

will this motor fit all four bolt hayward pumps
Hi Ken, Yes, this motor can be used on several Hayward Pumps.

Hi Edward, We will need the know the model of the pump in order to locate the seals needed when replacing the motor.
I installed this in May with the tune up kit following the instructions on your website. When I turned it on today all it did was hum. Why?
Hi Pat, If the motor just hums it could be a bad capacitor. The motor is still under warranty I've emailed you warranty instructions.
i have an a. o. smith motor on my pool. best i can tell, the no. is C48L2N1S or 6 and the rest of the no. is missing. frame no. looks to be 56C. will the ST1100 be a replacement? Thanks, Jim
I currently have an AO Smith HST110 pump on my pool that has failed, I'm looking for a replacement and cant seem to find that exact pump. I was trying to find the flow rate for the HST110 so I could make sure my replacement was comparable equipment and found that the HST110 is listed as a replacement for UST1102, but still cannot find the GPM flow rate for this pump. Can you tell me the flow rate of the UST1102 or HST110 or suggest a cost effective replacement.
The flow rate doesn't only depend on the horsepower of the motor but also the impeller for that pump and every pump has a different impeller. But it doesn't stop there, it also depends on resistance or the distance between the pump and main drain. All of these factors come into play with the flow rate.
are all pump motors counter clockwise rotation from shaft end?
If you're facing the back of the motor where the end cap is, it will be going counter clockwise. If you're looking at the motor where the impeller attaches, it will be going clockwise.
I have an inground pool with a Hayward pump will this replace that ok?
We would need to know the model of your motor, or the make and model of your pump to determine if this motor is the correct replacement for your Hayward pump. With the pump information, we could also recommend the correct replacement seals for your pump.
I have a 1/2 h p a o smith motor attached to a Hayward super pump s p-1600. I would like to increase the motor h p . What motors will bolt up to the Hayward s p -1600
Here is a link to the Hayward Super Pump Parts page. It will list the higher HP motors available for this pump style. Keep in mind that when changing out a motor for a higher HP, you will need to change the impeller to match. We also recommend that you change the seals with the GO KIT 3 whenever you change out a motor.

Yes, this motor can be operated on 230 or 115 volts.
Do I understand correctly that this motor is watertight in operational underwater? Also what is the size of the shaft?
This motor is NOT watertight and will not operate submerged in or under water. The shaft diameter is 0.625" and the height is 2.82".

Butch, The gpm is determined by the pump housing that the motor is connected to not the motor.
I have a Emerson modle numberK63CXESD-4791 Will this pump that i am looking at work?
The correct replacement MOTOR for your pump would be the 1 HP Motor EE - Full Rate (B2841, B2841V1). You can also use the A.O. Smith 1 H.P Square Flange Up Rate Motor USQ1102 if you no longer desire an Energy Efficient motor. (the motor UST1102 will not be a correct replacement)

Hi Scott, for the Hayward Super Pump you will need this Hayward Super Pump Seal Kit
Im having to replace my dual speed pump and ive been told that I should just use a single speed pump instead. Ive been told the energy savings arent enough to pay the extra cost.
A single speed motor has the most energy consumption. If you are looking to save money on your electric bill, I would recommend a dual speed or a variable speed motor.

I am looing forr model c48k2n143b1. will this work with this model
Hello Justine, The correct replacement motor for model #C48K2N143B1 is the A.O. Smith 1 HP Round Flange Up Rate Motor - UST1102. We would also recommend that you replace your shaft seal whenever you replace your motor. You will need to identify the make and model of your pump in order to match the correct parts to your pump.

Will this motor replace sp3207z1m
Hello, First, I would need to correctly identify your pump. From the information you provided, you should have a Hayward TriStar Pump. If this is correct, then I would recommend clicking on the link to the parts page provided. On that parts page, when scrolling below, you will see the list of compatible replacement motors. (Please note that the motor you referenced is NOT a replacement for the TriStar Pump). Last would be to identify what horsepower (HP) your motor is and match it with the correct HP replacement motor.
I have a Hayward S 200 filter running a Magnetek part # 8-177019-20, 1 hp 230/115 v. The customer p/n is 1607-2-1-m. I am wondering if the USQ1102 is a proper replacement for this application. Patrick: let me check ? Thanks, Allen Patrick: you would need this motor here http://www.inyopools.com/Products7/00200017001331.htm ?OK. Great, Thanks. 6/1/16 today I tried to order this motor but can't find it in the product list. can you help? Thanks
Hi Allen, The UST1102 is the correct motor that will replace part # 8-177019-20.
What is the difference between the part# ST1102 and the UST1102?
Hello, The ST1102 is a full rated motor (high service factor) and the UST1102 is an up rated motor (lower service factor).
I have an older Hayward pump and it looks like the motor got fried (sparks and flames) when I turned on the pump yesterday to start work on opening our inground pool. The Hayward model # is C48K2N143., 1 HO, 3450 RPM, 15.0/7.5 amps, SF of 1.1. Is the A.O. Smith motor in my cart a match as a replacement? Thanks!
Hi Greg, Yes this motor would be a direct replacement for your C48K2N143 motor.
I have model C48K2N143B3 bearings shot, bolts broke off. What a mess. So I need a new motor and seals. Can you let me know what I need to get pool going shortly. My filter is SP2807X10. Thank you
Greg, The UST1102 is the correct replacement. You can find all of the seals for that pump on this page: http://www.inyopools.com/pool_parts_hayward_max_flo.aspx
I have a AO Smith pump Model: C48K2N143B3 1HP and a Hayward Model SP3907X10AV. Does this pump work and what tune up kit goes with this unit?
The C48K2N143B3 cross-references to this UST1102 as being the correct pump motor replacement. But that pump model number does not jive with the other Hayward model numbers we have on the books. Are you sure that is correct?
I have a Super ll C48K2N143BS. Do you have the match for my pump. Thanks
Yes, this will be the correct motor for you unit. Also remember to change out the seals and gaskets. That will be GOKIT2.
I have an 1102 Motor a little over a year old, the motor hums when power applies but does not work? Could the shaft be stuck?
The shaft, and more likely the bearings, have probably seized due to a seal failure.
Is there a difference between Type UAC & UAK ? Thanks
Hi, UAC and UAK are the same which refer to the code for the electrical design of the motor's capacitor start/capacitor run.
What is the Gallons Per Minute? Replacing an older model AO Smith motor for pool. Thank you for your time. dm
Hi Daniel, The GPM is base off of the pump, not just the motor. If you can provide the model number of the pump you have and the "Feet of Head" of your pool we can tell you the GPM.
i have a replacement pump already. model number is ust1102. I see you have what looks like the same one. the only thing i noticed is some of the info on the sticker differs from the description on yours. for example next to thermally protected mine say's cet53cy.
Hi Angelo, As long as your motor says UST1102 then this motor will be the direct replacement even if there some slight variations on the label.
I wish to replace a UST1102 model C48K2N143C1C motor on a Hayward super pump. Do I need to buy any gasket kits in addition to this motor to do the job. Is removal and installation as simple as working the 4 holding screws on the round flange?
Can I replace an ST1102 with a UST1102. The only difference I see is the service factor rating. I am not sure that I require a service factor 1.5
what would cause the water level in the strainer basket to go down just below the pipe coming into the strainer?
You most likely have a bad pump lid gasket or bad a bad o-ring gasket. what is happening is the bad seal is allowing air to enter the pump cavity and not allowing the pump to fully prime. This can be harmful to your motor. I would recommend identifying your pump manufacturer and model in order to match the correct lid gasket. If this does not resolve your issue, I would identify the same information for the diverter valve.

Looking to replace a C48K2N143B1 1HP motor on a SP2607X10 Hayward pump, but concerned about the round flange description in this replacement. What replacement motor do you suggest?
This is the correct replacement motor. The motor is a round flange.
what's the diffence between a full rated (ust1102) and uprated motor (st) beside price
Full rate motors have a higher total horse power than the up rate models.
is this motor outdoor rated ?
Hi, This motor is suitable for outdoor use.
Would it be a good idea to order kit in case I have other problems when replacing motor ?
Yes it is wise to have the seal kit there in case you did need to replace more seals than expected.
I have a Marathon Motor C1318 and I need a Gokit. Do you have something that replaces that/
The go kit would be dependant on the front pump housing model that the motor is bolted to.
will a ust1102 replace a c48k2fc15
Hi Al, I was not able to cross reference C48K2FC15 to the UST1102 motor. Can you send us photos of the motor label and of the pump housing to firstname.lastname@example.org we can try to locate the correct for you.
I have a a.o smith 1.0 spl pump for the pool and the pump part number is 186533-22/rpm 3450 and I looking for a replacement.
The replacement motor is part BN25.
Is the Seal 201, Extra Heavy Duty PS3868 the correct seal for the ust1102 motor and do you do price match
The shaft seals are dependant on the front pump housing model that the motors bolt to and not the motors themselves.
does this motor come with the pump seal instelled
All motors unfortunately do not come with the seals installed because the seals vary based on the front pump housing models. In order to cross reference that seal needed you will need that housing model or name.
yesterday, I purchased a replAcement motor for the C48k2n143b1 at my local Hayward dealer... However, the motor was bigger around than the original... The heights of the saddle that cradles the back of the motor will not let the back of the motor lower enough for the pump face to match the pump housing... The dealer says this is the replacement motor???? What to do?
Hi Dave, You will have to remove the motor saddle from the motor stand in order to allow the motor to sit properly in the base.
i need a motor that replaces C48K2n143B1
This is the correct replacement motor.
I have a 10 year old Hayward SP 1607 Z1-M, 1HP Superpump that is leaking a lot. Is it even worth trying to find the leak and getting replacement parts or should I just get a new pump? Are there more efficient models made now? My pool is abou 25,000 gal and the filter can handle 125 gpm. Thanks.
HI Mike, You can replace the entire pump with the Hayward Super Pump VS Variable Speed Pump.
Is this motor a direct replacement for a magneto B625 ?
Hi Mike, The "B625" motor is the direct replacement.
is this a two speed motor
Hi Castillo, This is not a dual speed motor, p/n STS1072R would be the dual speed replacement for this motor.
I am looking to replace my c48k2n143B3 with dual-speed B975T. Will I need to replace the impeller and diffuser? Should I stick with UST1102 or maybe the energy efficient UCT1102?
Hi, The B975T can be used as a dual speed replacement for the UST1102 motor and would not have to replace the impeller and diffuser. However the final choice would be up to you.
I need a pump motor. Above ground Hayward pool pump. SP1607-Z-1-MXBK. What is the correct pump motor. My motor does not have a threaded shaft. Thx

I have a Hayward SuperPump ll, model number SP3010EEAZ, with motor model number K48L2N104. According to your cross chart, a UST1102 is a straight across substitute. Is this correct?
Hi James, The A.O. Smith 1 HP Full Rate EE Round Flange Motor (CT1102) would be the correct replacement motor for the Hayward Super II Pump (SP3010EEAZ). I would also recommend getting the Hayward Super II Tune Up Kit (GOKIT2).
Does the UST1102 is a replacement for C48L2DB11A8? Thanks
Gus- The UST1102 A.O. Smith 1 HP Round Flange Up Rate Motor will not work for you. The motor you need is a T1102. The T1102 has a higher S.F. and total HP. This is a motor that we do not have.

What go kit do I order yo go with uST1102
Susan, Unfortunately the go kits would be determined by the model of the pump not the motor. Do you know what model pump you have?
i have the hayward super pump sp2607x10, it looks like this part will work, but i don't see the model in the guide. can you help answer this for me?
HI James, The A.O. Smith 1 HP Round Flange Up Rate Motor (UST1102) will be the correct replacement motor for the SP2607X10 Pump. I would also recommend getting the Hayward Super Pump Tune Up Kit (GOKIT3).
What does "Up Rated" mean?
Hi Scott, The term "Up Rate" are used when motors have a low service factor. Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency.
Need to replace a motor on a Hayward RS750CA pump. It had an Emerson SP1607Z1 .99THP .75 FRHP 1.32SF motor. The motor also lists 115/230 volts 6.5/13.0 Amps and has a 56J Frame and is thermally protected. Would a replacement be the 1 HP UST1102 ? And since this pump is almost 10 yrs old are there any other parts I should consider replacing? Really nice web page you have. Lots of information and great videos!

Hi Bill, The UST1102 will not replace the T1102/C48A95A06 motor. We do not sell a replacement for the T1102 motor, you will have to reach out to another retailer.
I have Century Centurion 1 HP pump, CAT B228SE SERIAL 07611CH and PART 0-184981-23 TYPE CX FRAME U56J HZ 60 RPM 3450 VOLTS 230/115 AMPS 6.0/12.0. Is the (UST1102) the right replacement pump?
Hi Joe, The A.O. Smith HP Up Rated Thrd 56J Motor (B228SE) would be the correct replacement motor.
My existing pump model #C48L2N134B4 is the new pump #C48K2N143C1C compatible to the same impeller housing on the old pump?
No these two model motors use different model impellers.
Does this motor replace the model# C48K2N143B3?
Hello JP - The UST1102 is the correct replacement for model C48K2N143B3.
I have a UST1102 CET51ABM Model # C48K2N143C1C motor of unknown age, on a Hayward Super II pump without a model/serial number (the label on the wet side of the pump is blank). I have a broken impeller, marked Hayward SP3007-C, and broken diffuser, marked Hayward SP3000-BN. The intact seal plate is marked SP3020-E. Should I replace the impeller with the 3/4 HP SP3007-C, or am I better off getting the SPX3010-C? Is there any way to guess the model/ serial number of my Hayward Super II pump?
I am replacing a Hayward Super Pump 1hp motor C48K2N143. I was told that the UST1102 would work. Do I need anything else when I change the motor when purchasing it?
The only other item that would be highly recommended to replace would be the shaft seal ( 5110-11 ) As to the other o-rings in the system, it is up to the age of the whole pump. If it is a couple of years old, I would not worry about it. If it is older than 5, there is a kit that contains all the o-rings and the shaft seal - it is a GOKIT3. Other than those, just inspect the impeller and difusser for any wear and tear.
Does the sp 2607X10 require a impeller wear ring?
Andy- The SP2607x10 Hayward Super Pump 1 HP Single Speed does not need a wear ring for the impeller.
I would like to order a replacement pump motor and gasket/seal kit for my 1HP superpump model SP-1607-Z1-M (An A.O Smith sounds like it is the best one to get?) Can you please tell me what exactly I need to order and if you have them in stock, so when could I anticipate receiving if I ordered today Thanks
will this pump replace c48k2n143b1
Hello James yes the UST1102 is the replacement for c48k2n143b1
I have a Hayward super pump model sp2607x10 with a.o smith b128 motor. It is making a loud whining noise. If I replace it would this be the correct model and is this a new or refurbished motor?
Yes the UST1102 would be the correct motor replacement as long as the motor that you are replacing is the original gold Hayward motor. The impeller and diffuser need to be the originals as well. The B128 was not the original model for this pump. These motors are brand new.
I have a Hayward Max Flo pump SP2807x10 on a salt pool. Original Hayward motor lasted 5 years but was replaced last year with AO Smith UST-1102. All seals were replaced. No leaks, no problems until it simply quit working. Hums but never starts. Start capacitor is good, impeller moves freely. I'm ready to replace the motor but am concerned that the last UST-1102 lasted only 1 year. Pumps only run 4 hours/day, so why only 1 yr? What seal kit do I need if I replace with another UST-1102 motor?
Hi Linda, You will need the Hayward MaxFlo Saltwater Tune Up Kit with the UST1102 motor.
this model motor was already a replacement on Hayward pump sp3007x10a2bh for salt system. was this the correct replacement the first time and should i get it again? It would be the 3rd motor in about 10 year span.
Hi Chuck, The A.O. Smith 1 HP Round Flange Up Rate Motor (UST1102) would be the correct replacement motor. I would also recommend getting the Hayward Super II Pump Saltwater Tune Up Kit.
Which gasket goes with a UST1102 with a Hayward SP2607X10?
Hello, You will need a GOKIT3 (Super Pump Tune Up Kit) if you have the Hayward SP2607X10 Super Pump.
What is the cost of the replacement "green version" of the Smith 1 HP Round?
Hi Kurt, there are 3 versions of this motor which are more energy-efficient than the UST1102 motor. In order of energy efficiency they would be the UCT1102 Single Speed Energy Efficient Motor, The 2-Green Dual Speed Motor and the most efficient is the VGreen Variable Speed Replacement Motor. Here is an article on helping you to decide if a Variable Speed or Dual Speed Motor is Right for You, this article should be helpful in determing which is best for your needs.
Can I replace a 1.5 HP motor on Hayward Super II with this 1 HP?
Hi Linda, You could replace your motor with a 1 HP motor but you will need to change your impeller to a 1 HP Hayward Super II Impeller. If you stayed with your current 1.5 HP impeller then it would overwork the 1 HP motor and cause the motor fail prematurely.
I replaced my motor with this model 3 years ago and the bearing seem to be failing. Do you sell replacement bearings?
Yes the front and rear bearing is part number 5270-31.
I have a C48K2n143B1 motor that is blown and need a replacement motor. I also need the gaskets for the pump housing, which is model SP2607X10. Can you let me know what the part numbers are for the motor and the gaskets. Is there anything else that needs to be replaced when I replace the motor.
Will this motor fit my SP3010EEAZ pump. The current motor is a K48L2N104.
Tony, While the motor will fit, you will need to change the impeller since the total HP does not match what you have now. The motor also runs at higher amps which means that it will cost more to run this motor.
I have a AO Smith 1 HP UST1102 and need to change the motor bearings. I think the shaft end requires a 304 bearing but I think the other end has a different size bearing (203 ??). Is that correct? Is there a pump seal that would need to be replaced if I just want to replace the motor bearings? My pump is Jacuzzi Magnum Force.
Hi Joe, The A.O. Smith 1 HP Round Flange Up Rate Motor (UST1102) requires (2) 203 Bearings (62032RS). We also have How To Replace the Bearings in a Pool Pump Motor - Part I & How To Replace the Bearings in a Pool Pump Motor - Part II to assist you with replacing the bearings in your motor.
I have Hayward pump SP2607X10, CURRENTLY had an Emerson motor 1081 1.5hp on it with the square, what do I need to purchase thanks
Wanda, The SP2607X10 uses a round flange motor. You will need to remove the square motor mounting bracket from the old motor to install it on the new motor. You will need the UST1102 motor. I would also recommend the GOKIT3 Hayward Super Pump tune up kit.
have a c48k2n143b1 motor that hums and no water flow. good voltage going in. what is a replacement motor and what seals will I need for when i replace the motor. if I could get stock numbers for both so I am positive I have the right things.
The UST1102 is the correct motor replacement for you. We would need the model of the front pump housing that the motor is mounted to in order to cross reference the correct seal kit for you.
I have a ao smith ast1102 motor and it says on line to replace the seal. Can you tell which seal I need?
In order to locate the correct seals and gaskets we would need the model of the front plastic pump housing that the motor is mounted to for cross referencing.
I have a c48K2N143B1 1 hp motor wired to run with 240v. The cap is no good and I am going to replace it but the existing one is rated for 125v. 161-193MFD. Should I be using the same type or use a 240v rated one.
If the existing one was rated at 125 vac then I would stay with that. Also looks to be the correct capacitor 5270-14 based off of the UST1102 model.
I have a 30,000 gallon pool and I currently have a Hayward Super Pump (Model: C48K2N143B1). Just seems to be making a whining noise and does not seem to have the power required to run the pool anymore. Should I replace with the UST1102? Or a different model. I have read that my pool may be a bit large for this pump and it may not run efficiently. If not the UST1102 which pump do you recommend?
Frank, Based on yoiur motor model #, the UST1102 wil lbe the correct replacement motor. Be sure to replace the shaft seal when you replace the mtoor.
I have a Max Flo 1HP motor # SP1607Z1M Its starting to hum, i'm going to replace it but I would like to up grade to a 1-1/2 motor for more water flo, is it possible. Also, your products are Great... I just replaced a motor and other parts for a freind that I purchesed through your company, and it works great.
i have a hayward sp3007eeaz , is the motor replacement the ust 1102 it also has c48kn143c1c on it, the sticker on it says ust 1102
Hi Pete, The UST1102 is the Up-Rated replacement motor to the original 3/4 HP Full Rated motor that originally came with the Hayward SP3007EEAZ model. So the UST1102 will work, would also recommend getting a Hayward Super II Pump Tune Up Kit (GOKIT2).
I have a sta-rite pump for sand system. Motor died but rest of pump is fine. Will this motor replace the sta-rite JWPA5EL-2A2 pump motor?
What is the flow rate for the A.O. Smith 1hp motor? I am trying to figure out how long to run the pump to filter the pool. The pool size is 18x36; deep end is 8.5ft. And the filter is a Hayward C4030. Thanks
Hi David, The flow rate will be determine on the Feet of Head of your pool. You can calculate your Feet of Head by following Step 7 of How to Size a Pool Pump for Your In-Ground Pool.
We just purchased a property with pool, the pump motor is C48L2N1-34C2. The pool has not been used in 3 years. Power is applied to the pump but it doesn't run - no hum, etc. What should I check?
Hi Bill, just a note first: If your motor is labeled C48L2N1-34C2, that is a full rated ST1102 motor instead of an uprated UST1102 about 1/2 HP difference. Now on your dead motor. Using a meter, check that you actualyl have power to the terminal of the motor and that it is the same voltage as how the motor is configured, 115V or 230V. Also check that the connection are tight. Then take the basket out and see if the impeller moves freely. If no, the bearing on the motor are probably shot. If impeller movers freely, check the start capacitor at the electrical end of the motor. See our guides under "pool pumps" for detailed instructions on any of these procedures.
I saw you said this was the replacement for a marathon c1318. Would the capacitor from this ust1102 fit the c1318 or can you tell me where I might find the capacitor for the c1318?
I just purchased this pump and installed it...my voltage is 120 but when I put the selector switch on the 115 option the motor doesn't do anything except hum...when I put it on the 230 option it runs seemly fine..should I return the pump or is it safe to run in the 230 v mode
Please double check the voltage running to the motor and adjust the setting accordingly. Also make sure all wiring to the motor is corrrect. I'd advise having a licensed electrician or pool contractor confirm this. If all looks correct at this point then I would look into a return or warranty.
I have a Hayward pool pump with an A.O. Smith 1 hp motor Century Centurion motor serial # 168083M cat sn1102. What would be the replace motor for that unit? Thanks
The replacement motor is the sn1102.
I have to replace a Pump motor for a Hayward SP1607Z1M. Looks like this motor will work, but should i upsize to a 1 1/2 HP motor and would it work with the Hayward Super Pump? My pool is about 28,000 gallons. Thanks.
Hi Steve. With your size pool I would definitely recommend going to a 1 1/2 HP uprated motor - UST1152. You would also have to replace your pump's impeller to the next size up: Hayward Impeller, Sp 2610-c. Also check to make sure your current filter is compatible with the new pump for water flow.Should be able to handle ~60 to 80 GPM
Need a replacement motor for a Jandy jhp1.0 pump, the motor is a 1hp, with a 56j frame. Is there additional info needed, or does 1hp and 56j define the motor?
Tom, The replacement motor for your Jandy JHP1.0 Pump would be the 1hp 56J Thrd Full Rated Motor (B128). I would also recommend getting the Jandy JHP + JHPU Pump Series Tune Up Kit (GOKIT77).
I have a series 6002, 1 hp a.0. Smith motor- model # k48L2n104. Will this motor work on my HAYWOOD SUPER PUMP.

I have a 20'x40' inground pool with a 11/2 h.p.hayward super pump, Can I replace this with a 1 h.p. super pump?? Thank's Rick
Hello Rick, With the sizing of your pool you would not want to go any smaller than 1 1/2 hp. If anything your pool would be more efficient with a 2 hp pump.

Hi Mike, The UST1102 and the B228SE are very similar motors and you would probably be fine with the UST1102, however we do carry the B228SE Replacement Motor and I would suggest this motor as it is the exact same motor as what your currently have.
On my old (century) motor the frame is a m565 cat-b654 serial #bs3-167 type cx will this motor fit?
We would suggest going with the exact same motor you currently have which is the B654 Replacement Motor.
Does this UST1102 replace the SP1607Z1M?
Valerie, Yes the UST1102 replaces the SP1607Z1M. Please be sure to replace the shaft seal when replacing the motor.
What is the diameter of the motor casing? I have a SP2607X10 pump and two different stores have tried to sell me a motor that is larger than the one I'm replacing insisting that it is the correct replacement. The problem is I can't get the faces to meet without modifying the pump.
Hello, The motor is approx. 5 5/8" in diameter.

I have a Hayward Pump Model SP2805X7, with a 3/4 HP motor model C48J2N131B3 that burned out. My filter is a Hayward C-500. Can I replace the motor with the UST1102? If so, what other parts should I replace?
Tim, Base on the flow rate of your Hayward C500 Filter, increasing the HP of your pump from 3/4hp to 1hp will not be a good for that filter.
I'm looking for a replacement motor for my Hayward super pump 2 self priming 1hp for inground pool. Is this the right one?
Hi Courtney, If you could double check the service factor (S.F.) on your motor label if it reads 1.1 then this is the correct motor for you. If the S.F. reads 1.5 then you would require The 1 HP Full Rate ST1102 Super II Replacement Motor. When replacing either motor I would suggest a Hayward Super II Tune Up Kit.

Any issue with hooking with pump up to 220 electric current?
Chris, This motor comes set for 220v hook up. So your two hot wires will go on L1 and L2 and your ground.
I need to replace an A.O. Smith self prime super pump 1/2 HP motor Model s48h2n122b1 in Central America. The motor is overheating and turning off. I am hoping to buy a new motor to bring down. My filter looks like it is rated for 40 GPM, do you have a 1/2 HP motor so I do not have to replace the filter right now?
Hi John, You would be able to go down to a smaller horserpower which would save you on operational costs. When reducing your motor size you will need to replace the impeller on your Hayward Super Pump. So if you wanted to go down to 1/2 HP you would require the Hayward 1/2 HP Motor and the Hayward 1/2 HP Impeller. We also always suggest the Hayward Super Pump Tune Up kit when replacing a motor.
I have a hayward super pump model number C48k2n143b1 (sp1607z1m), would this be the right motor to replace it?

Will UST 1102 replace an st1102?
Both motors will mount up to your existing pump but are technically two different strength motors which may not be compatible with your filter and or other pump parts.

I'm replacing my Hayward Max Flo motor with your UST1102 and GOKIT1. Everything seems good, but in the on-line tutorial, it shows an impeller ring. I don't find an impeller ring. And I can't find a replacement on your site for my pump. Can I assume I don't need one??? Thanks!
Jeff, The Hayward MaxFlo pump does not have an impeller ring. You will simply need the motor and the tune up kit.

Hello Eddie - That is the correct replacement motor. Make sure to get a new shaft seal as we. That is part number 5110-11 for the Hayward Max-flo. If you have a salt system, it would be seal number 5250-235.
I need to replace my Hayward 2 A.O. Smith pump motor. The model number is K48L2N104. This is a 1hp motor. Which replacement motor do you recommend? Are there a few I can choose from?
Hi Shane - Here is the Direct Replacement Motor for the K48L2N104 you would also have the option to upgraded to a Dual Speed Motor which typically saves you 50% on our operational costs over your current single speed motor. Here is the Dual Speed version of the K48L2N104.
I have a old Jacuzzi 94027110 and I want to know if this motor will replace the one I have? If so is there any special wiring or anything else that will need to be done or can I just take the old motor off and put this one into the housing and wire it? I would rather not buy a whole new pump unless it is absolutely necessary.
Yes the UST1102 would be the replacement motor for your 1 HP Jacuzzi Magnum pump and there would be no different wiring required, we would suggest a Jacuzzi Magnum tune up kit when replacing your motor which includes a shaft seal, o-rings, gaskets and lubricant. Typically if you use your old shaft seal it will not mate up properly which will cause leaking.
I need to replace the motor on a Hayward Super Pump 3/4 hp. Can I go up to a 1 hp and what difference does that make? If so, does anything else need to be changed out? This is for an inground 16' x 32' pool.
You could go up to a 1 HP motor which would give you a higher gallon per minute rating (GPM). On a typical pool a 3/4 HP Super pump will have an output of 50 GPM's where a 1 HP will have an output of 65 GPM's. You would want to make sure that your filter could handle this increased flow rating from the 1 HP motor your filter should have a label on it which says max flow rating, this would let you know how many GPM's the filter can handle. If you increased your motor to 1 HP you would need to also replace your impeller to a 1 HP impeller, we would also suggest a Super Pump tune kit.
Will the AO Smith UCT1102 cost less to run than the UST1102?
Yes, the UCT1102 will cost less to operate compared to the standard UST1102. Depending on how the motor is cared for, it should last several years. When replacing the motor, I would recommend buying a tune up kit based on your pump model and age.
Are all pool motors wired the same?
No. The motor should be wired following the wiring diagram on the motor itself.
My pool pump motor makes a humming noise when I try to start it. Will replacing the motor fix my problem?
Replacing the motor should solve your issues. Aside from the motor, you will need a GOKIT to replace the seals on your pump.
I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?
Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.
I'm trying to find a replacement motor for my pool pump but my model number doesn't match what you have listed as the model number. My model number begins with a C48 and yours begins with an SP. Please help.
What we have listed on our chart pages is the pump model number. The model number you have will just identify the motor. If you look on the plastic housing on the pump there should be a sticker which will have the pump model number. You can usually find this by the discharge port on the pump. Once you locate it you can choose the correct replacement motor. Be certain to change the shaft seal and gaskets as needed. You can use our >How to guide if you need help.
Why should I purchase a Tune Up Kit?
A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.
Why do I need to purchase a new shaft seal?
We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.
What is Service Factor?
Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

My brother first thought the capacitor was dead, but we put in a new one, and it didn't help. He told us that we needed a new motor, and that he could take off the old one, keeping the frame. So we took a picture of the motor's specs and searched for the best price online. I found yours on your site, ordered it on 9/22/17, and it was delivered on 9/26/17. My brother took off the old motor being careful not to break the seal, installed your new motor, and it purred like a kitty cat when we turned it on. Thank you so much!

Well I got a price at INYOpools.com on a motor that exactly met the specs of my old Super Pump that was 1/3 the cost. I could not believe it and it came with free shipping. So I gave it a try. I watched the videos on replacing it and wallah..... It works like a charm and quieter than ever before. Great website and great online assistance.

After confirming the correct pump needed with INYO, I placed the order adding the seal kit recommended. I took on this case motivated by wanting to save over $ 300.00 from two local pool shops quotes. After watching the INYO Pools tutorial video twice I started. About three hours later it was time for the moment of truth. With a flick of the breaker and the timer switch we were back in business. The process could not have been explained any simpler than it was. INYO was right there next to me every step of the way. I used the video on my smart phone and paused it after each step to make sure I was doing it correctly. Thank you very much for providing the expert installation instructions and the online support I needed for the "Bonding Wire". I had no clue what that was but your web site resolved the questions and I finished the job.

I watched the video on the disassembling of the pump motor to see if it was doable on my part which I'm happy to report it was. I then called INYO Pools to make sure I was ordering the right motor. I also ordered a new impeller and seal kit to complete the rebuild. The tech at INYO Pools was also very helpful and told me to call if I ran into any problems. I'm happy to report everything fit perfect and it took about 2 hrs to complete.
(5 out of 5 stars) Excellent Pump Moter Replacement
Reviewed By: PoJo from Clarence, NY ()
Pros: Awesome fit - excellent replacement
Tip to get the impeller off the old pump moter: use a 7/16" open ended wrench - it slides in near the capacitor on the electrical side... rotate the impeller until the wrench slides into place at the end of the shaft and then one person holds the motor and the wrench while a 2nd person loosens the impeller off with bare hands by turning the impeller counter clock-wise.
