Question

Asked on 09/02/2015 by Ron

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?

Inyo Answer

Answered on 09/02/2015 by Product Specialist Brian M.

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.

This UST1102 is the correct replacement motor and the seal kit for the Super Pump is gokit3 or gokit3salt for salt pools. The general lead time for motor orders is 1-7 business days in the continental U.S.

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?

Inyo Answer

Answered on 08/18/2015 by Product Specialist Hector F.

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.

Question

Asked on 08/09/2015 by LInda

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?

Inyo Answer

Answered on 08/12/2015 by Product Specialist Lennox H.

Hi Linda, You will need the Hayward MaxFlo Saltwater Tune Up Kit with the UST1102 motor.

Inyo Answer

Answered on 08/10/2015 by Product Specialist Lennox H.

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.

What is the cost of the replacement "green version" of the Smith 1 HP Round?

Inyo Answer

Answered on 08/03/2015 by Product Specialist Patrick P.

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.

Question

Asked on 08/03/2015 by Linda

Can I replace a 1.5 HP motor on Hayward Super II with this 1 HP?

Inyo Answer

Answered on 08/03/2015 by Product Specialist Patrick P.

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.

Question

Asked on 07/27/2015 by Chris

Inyo Answer

Answered on 07/26/2015 by Product Specialist Hector F.

The UST1102 is the correct replacement motor and the 2 option seal kits that you can use are GOKIT3 and GOKIT3SALT if you have a salt water swimming pool.

Question

Asked on 07/25/2015 by Tony

Will this motor fit my SP3010EEAZ pump. The current motor is a K48L2N104.

Inyo Answer

Answered on 07/26/2015 by Product Specialist Alex V.

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.

Question

Asked on 07/25/2015 by Joe Curley

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.

Inyo Answer

Answered on 07/29/2015 by Product Specialist Lennox H.

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.

Inyo Answer

Answered on 07/26/2015 by Product Specialist Alex V.

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.

Inyo Answer

Answered on 07/23/2015 by Product Specialist Hector F.

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 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.

Inyo Answer

Answered on 07/16/2015 by Product Specialist Hector F.

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?

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).

Asked on 06/29/2015 by Bill

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?

Inyo Answer

Answered on 06/29/2015 by Product Specialist Dennis R.

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?

Inyo Answer

Answered on 06/29/2015 by Product Specialist Lennox H.

Hi Chad, The Capacitor for the UST1102 is the 161-193 MFD 110-125 VAC Start Capaciotor (BC-161), I'm not 100% sure if they uses the same capacitor. You can compare the numbers to be sure.

Inyo Answer

Answered on 06/24/2015 by Product Specialist Hector F.

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.

Inyo Answer

Answered on 06/23/2015 by Product Specialist Dennis R.

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

Asked on 05/22/2015 by Tim

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?

Inyo Answer

Answered on 05/27/2015 by Product Specialist Lennox H.

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?

Inyo Answer

Answered on 05/14/2015 by Product Specialist Patrick P.

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.

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?

Inyo Answer

Answered on 04/20/2015 by Product Specialist Patrick P.

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 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.

Inyo Answer

Answered on 07/10/2014 by Product Specialist Patrick P.

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.

Inyo Answer

Answered on 07/10/2014 by Product Specialist Patrick P.

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.

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.

Inyo Answer

Answered on 01/18/2012 by Product Specialist Patrick P.

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?

Inyo Answer

Answered on 01/12/2012 by Product Specialist Patrick P.

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.

Question

Asked on 01/12/2012 by Guest

Why do I need to purchase a new shaft seal?

Inyo Answer

Answered on 01/12/2012 by Product Specialist Patrick P.

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.

Question

Asked on 01/11/2012 by Guest

What is Service Factor?

Inyo Answer

Answered on 01/11/2012 by Product Specialist Patrick P.

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.

   (5 out of 5 Stars) Excellent Pump Moter Replacement

Reviewed By: from Clarence, NY ()

Pros: Awesome fit - excellent replacement

Cons: none

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.
