Hi, I am looking for a motor that compatible and well fit for STA_RITE, motor mode 5P6R6D-209 with 3/4 horse power. Can this motor fit in ?
I have a pool pump motor that was running, I turned it off to clean the filter and now it will not start. It is hot to the touch. The motor is a 1 hp Emerson 1081 with a 4 bolt flange. Would it be cheaper to rebuild it or purchase a replacement?
In some cases it is cheaper to rebuild the motor by replacing the bearings but that is not always worth it if the body of the motor is corroded or there are other internal parts that have burned up. Motors are designed to run hot at around 140 degrees. Most pool owners replace the motor in these instances though. You would need to know the model or part number of the motor and front pump housing that the motor bolts when calling in to place an order.
have a C48K2PA105 will this motor work
Hello Cheryl, the motor that matches your part number C48K2PA105 is Motor, Sq Flange 1hp (small Barrel) (usq1102, B886, 718690720) under alternate part numbers. Although the USQ1072 has the same square flange facing, the frame and additional motor ratings are different. I would not recommend replacing your motor with the USQ1072. Also anytime your replacing your motor you need to change out your pump seal to protect your new motor from water damage.
I have a Stay-Rite Max-E-Glass II pool pump. Model no. is P4E60-186L. It is a 3/4hp motor, FR 48 and SF 1.65. I have 2 questions. First, which A.O. Smith motor would replace this pump? The second question is is there a more efficient motor available that I could use that would fit the existing parts so I would not have to get all new parts.
Hi, Brian. The QC1072 is the motor you'll need for that model pump which is the most energy efficient single speed motor available and you can reuse your existing parts. The only thing that we'll recommend that you get is the Sta-Rite Max-E-Glas II / DuraGlas II Tune Up Kit - GOKIT38.
I've got a Hayward 6060 booster pump with a A.O. Smith motor burning out (cycling off and on and over heating). Bearings are toast as it's been whining for a couple of years. Motor model is: C48D62A04 and the specs shown on your label are the same as mine. Will the USQ1072 work for me? Thanks! Mark
Hello Mark- The correct replacement motor for your motor model #C48D62A04 is the 3/4 HP EE Full Rate Single Speed Motor (B661, B2661). Although the USQ1072 has the same square flange facing, the frame and additional motor ratings are different. I would not recommend replacing your motor with the USQ1072.
Looking to replace our pool motor. A.O.Smith C48J2PA105C #U27-1221. 115/230 3/4hp 3450 rpm. I am pretty sure I am choosing the correct motor. Can you also let me know if I should replace the seal also at the same time. If so, which one would I need for this motor? Thank you Ron Brazeau
Good morning Ron, The correct replacement is a USQ1072 . I would also recommend getting a gokit. Which is a kit that has the o-rings and shaft seal you will need. I would just need to know what type of pump you have for this.
Should I replace the rubber seals when replacing the motor? If so, what would I need to order for the above pump motor?
Good morning Ron, We would need to know what type of pump you have to determine the shaft seal and o-rings. We sell gokits for a wide selection of pumps that have everything you need . Let us know what type of pump you have not the motor and we can point you in the right direction.
What is the flow rate of st1072. 3/4 hp
Hi. Unfortunately, the flow rate is based on the pump, not just the motor. If you can provide us with the pump model and the feet of head of your pool we can calculate the flow rate of your pump. For more info about calculating the feet of head of your pool, you can read our How Do I Calculate Feet of Head for My Pool? Blog.
The back bottom cover of the motor has completely rusted away. Can I just replace the cover or do you think there is a water leak? Thanks
Hello Roy, could you please send us some pictures at email@example.com so we can better assist you with this.
It appears my pump is leaking, what is a possible reason.
It is very likely you have a bad pump/shaft seal if water is leaking from where the motor mounts to the back of the pump. Worn or stretched out o-rings can also be a cause of a leak.
My moyer now only humma then trips off. Its a C48J2PA105. Can't read anything on the other labels because they're too worn. How old is this motor & should I replace it? Also, what other parts do I need to replace with it? Thanks.
Hello Teri, yes that USQ1072 matches the C48J2PA105 model number. To find out what seal kit you would need, we would need to know the model of the pump which is either located on the side of the basket housing or on the front of housing (where the basket and lid are).
Is the use 1072 a direct fit for my sta-rite pr2d motor including 4bolt gasket? Thank you
Yes, that would be a replacement motor for your pump if what you currently have is a 3/4 HP motor. If not, if you are wanting to go with the 3/4 HP motor you might have to change impeller and diffuser as well.
Is the use 1072 a direct fit for my sta-rite pr2d motor including 4bolt gasket? Thank you
Hi Leo, In order to confirm if this motor is a direct replacement we will need the motor MOD # or the complete Sta-Rite model number.
I need to replace a STA-Rite Dura glass c48j2pa105c1. Which motor do I Need? The pump Model is p2ra5d-180l that it connects to.
Hello Mike, your number c48j2pa105c1 came up with a A.O. Smith 1/2 H.P Square Flange Full Rate Motor - SQ1052 and that is not a 3/4hp, also with your motor replacement. I would also recommend a GOKIT depending on whether yours is Pre 1998 or 1998 to present please click here for GoKIT.
What is the GPM (gallons per minute) rating for this motor when used with a Sta-Rite P2RA5D-124 pump? I am considering a pool water sanitizing system that requires a minimum GPM. Thanks in advance.
I apologize for the delayed response. The flow rate is going to depend on not only the horsepower, but also the total resistance or the distance in feet from the pump to the main drain. With that information I'll be able to tell you what the flow rate for that pump is.
Hello, 6 years ago I replace my 1 hp motor with a 3/4 hp motor in order reduce electric use. Recently the filter/pump does not want to prime. I was going to replace the motor with a 1 hp unit. should I consider a 1.5 hp unit instead?
It's all going to depend on if your filter can handle the increase flow rate. Let's try to get to the problem of why your pump isn't priming before anything. What model is your pump.
Can this pump be mounted in vertical position?
Hi Victor, This motor is mainly used on pumps with a horizontal application.
Which is the correct Tune-up Kit for replacing the AO Smith USQ1072 motor?
Hello, In order to determine the correct tune-up kit for your PUMP I will need to know what pump you have. If you can provide the pump manufacturer and model information, located on the wet end of the pump that the motor attaches to.

The motor i am replacing has a capacitor mounted on top. Does the USQ1072 have one or is it built in?
Hello Jeff - The USQ1072 does not have an external run capacitor. The energy efficient version of the USQ1072 has that capacitor. The model number for the energy efficient version is UQC1072.
How do you change wiring in motor from 115V service to 230V service?
If you are wiring for 115V, the three wires to the pool pump will be black, white and green. Attach the white wire to terminal 1 of Line 1 (L1). Attach the black wire to terminal 3 of Line 2 (L2). Attach the green wire under the Ground screw (GND). The black plug is shifted in position so the the black wire is attached to terminal 4 Line 2 (L2) and the white wire is attached to terminal 5. Note: in this position the white arrow on top of the 2 prong black plug is pointing at the 115V label.
What is the GPM of this model?
The GPM is not solely determined by the motor. This motor is used on several pumps and this will cause the GPM to change. You will have to look at the power curve of your pump. This will give you the GPM rating.
I just installed a brand new motor. After running for about 5 mins., I could smell the motor and the housing was very hot to the touch! I turned the pump off right away! Is this normal?
Hi Stephen. A running motor that is too hot to touch is not necessarily overheating. If the automatic protector is not tripping and the actual running amps do not exceed the maximum amps on the nameplate, the motor is not overheating. However, you should still check the conditions that make a motor overheat. For example, the supply voltage to your motor may be too low due to power company power demands or inadequate wire size between the breaker box and the pump . See our guide on "How To Troubleshoot a Pool Pump Motor - Motor Overheated" for more information.
What kind of capacitor does it have?
The USQ1072 uses a 124-149 MFD 125V start capacitor.
MOD C48K2N143C2C I NEED THE PLASTIC PEICE THE WIRES HOOK TO
Hi Charles, You would require the Terminal Board here.
I will be buying this motor, but I don't see a go-kit for a 3/4 HP motor. What should I by??
Hello Alicia. The motor you are looking at can fit on many different pump models. The GO-KITs are determined by the make and model of pump the motor is going on. If you can get us that information, we can get the right GO-KIT for you.
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.
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.
(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.
(2 out of 5 stars) Don't expect long lasting
Reviewed By: Terence Y. ()
Cons: short lifespan
Ours lasted less than 2 years, then started grinding and howling so loud that I thought it was going to explode. Pool pumps should be able to last longer than that. Our previous one, a genuine A O Smith one, had lasted 13 years.
(5 out of 5 stars) Wonderful swimming pool pump motor!
Reviewed By: Tommy from Maryland ()
Pros: Great product, great company. Thank you
Cons: Can't think of any
This motor is lighter, very quiet, easy to assemble! I have advice to add for anyone needing to buy a motor: I found it impossible to remove my old motor from the seal plate of the pump without breaking it. (The piece the motor bolts to) I strongly advise buying the motor, seal plate and seal, get the salt water seal its heavy duty, and spend the extra $25 or so on the oring seals, the big one for the seal plate and the small one for the diffuser. Do it once and be done.
(5 out of 5 stars) Replacement motor
Reviewed By: Kevin P. from Yakima,Wa ()
Pros: very easy swap. perfect fit
My old pump(motor actually) was creatinging a rather unusual problem. It would start up fine but my filter pressure would drop over time resulting in diminished flow. Changed my sand, checked for leaks, obstructions etc. Turned out the motor would heat up and the bearings would drag decreasing the output. This was an old 3/4 duraglass pump. The swap was a piece of cake taking less than 20 minutes. Works like a champ and quiet as well.
(5 out of 5 stars) Great price, fast shipping, and QUIET!
