At one point or another, you will need to replace your pool pump motor. Replacing it with an exact match is important otherwise the motor may burn out prematurely. There are a few things to look for when ordering a replacement motor. This guide will help you understand the world of swimming pool pump motors a little better.

Step by Step

Top

Step 1

The easiest way to find out your motor information is on the motor label itself. It will usually list the model or category number. The motor pictured to the left is an AO Smith UST1152 (C48L2N134C1).

Step 2

If you have an AO Smith motor and a part number similar to the UST1152 (C48L2N134C1) is visible, you can enter it into the search by keyword or part number on our website and it will bring you directly to the motor page.

Step 3

Once you're on the motor page, you will find the motor specs listed. You will want to compare and the specs to what is listed on your current motor label. The most important information you will need are the horse power (HP), amps, voltage, service factor (SF), hertz (HZ), frame (FR) and revolution per minute (RPM).

Step 4

If the model or category number is not legible on the motor label, you will need the information on the pool pump (pump housing) to find the right motor. The label will likely include the pump model and the serial number. Unfortunately only the manufacturer has access to the serial number.

Step 5

If you insert the pump model (SP2810X152) in the search box and click go, it should return with a result. Once on the item page, click on the parts tab, then on the replacement parts link.

Step 6

Once on the parts page, you should be able to locate your replacement motor. Once again, you will want to compare and the specs to what is listed on your current motor label (if legible).

Step 7

When I receive a call from a customer asking for a replacement motor, there are a few key questions I will ask: What is the manufacturer and model of the pool pump (not the motor)?, What is the horsepower of the motor?, What is the frame of the motor?, What is the voltage?, What is the service factor?, What is the RPM?, and more general information about the pump (color, shape etc.) if necessary. If all else fails, I will ask for a photo of the pool pump.

Step 8

The reason I ask these questions is because this key information will lead me to a replacement motor. Let's look at the questions: What is the manufacturer and model of the pool pump (not the motor)? If the customer tells me Pentair, then I know that I will likely be looking for a square flange motor (56Y or 48Y frame) because Pentair/Sta-Rite and Jandy (sometimes) use these types of motors for their pumps. The only difference between the 56Y and 48Y is the circumfrence (width) of the motor. They will both mount to the seal plate but the 48Y will need an optional spacer (that comes with the motor) to sit on to make up for the difference in size.

Step 9

If it's a Hayward pump, I will likely be looking for a round flange (56J frame) motor. Jandy also uses 56J frame motors on some of their pump models. This isn't always the case but the questions above will narrow down my search. Once I figure out the type of motor the customer needs, I then try to match up the pump model number or motor specs.

Step 10

If all of the above fails, I will ask for a picture of the pump housing and the motor label.

May I change original motor in pump Hayward SP2705x7 with Century HSQ095 motor? Thank you
 Reply

InyoPools Product Specialist  Posted: 7/9/2019 

The model number HSQ095  does not cross-reference to a specific motor, but the correct motor replacement for the Hayward Max-Flo II is the USQ1072 or the SPX2705Z1M.

I put the capacitor on but it runs for 30 minutes and the motor shuts off on the thermo overload. No sure what to do it's a 110 volt cap

We recently had a new 26,218 gallon pool with deck fountains and a water fall. The water features will not work together due to lack of water flow (Pressure). The current pump is a SP3400VSP with an additional waterfall pump recently added for waterfall only. The current Ft per head on the pump is 125.8. My concern is the pool plumbing is 1 1/2" lines and the main pump can not pull enough water from the suction. Is there another pump or recommendation to help assist with this issue? Thank you,

I'm replacing a Century Pump - HSQ1102. The frame is listed as a Y56Y and not simply 56Y. Is there a difference. thanks
 Reply

InyoPools Product Specialist  Posted: 4/15/2019 

Hello Mike - The short answer is no. There is not a significant difference. The Y before the 56Y indicates the overall length. This doesn't impact anything unless your motor butts up against a wall and there is no chance anything longer will work. For more information, check out our article titled "What Does My Pump Motor's Frame Rating Mean?".

I have a pentair superflo vs pump 342001 1.5 hp, the replacement motor listed is 353134S. Are there other replacement motors that would fit the pump housing? I have already replaced the shaft seal in the current motor to stop a leak. Now the bearings are starting to go out, and all the parts are no longer covered by the warranty. The VS features were convenient and did save on the utility bill; however, the replacement motor without a drive assembly and cover is very expensive. Would you recommend options for another motor? Thank you.

InyoPools Product Specialist  Posted: 2/27/2019 

Hello Paul - The single speed motor option would be part number B2748. We also have a variable speed option, part number ECM27SQU.

Hello Juan - If you're looking to replace the entire pump, we recommend Pureline model PL2603. If you want to keep the existing pump and only change the motor, the replacement is model B123.

InyoPools Product Specialist  Posted: 1/16/2019 

Hello Jerry - going by the c48ab46a01 number, the replacement would be the USQ1152. Do you need help finding a replacement shaft seal or gasket kit to complete the installation of your motor? If so, reply with the model number of the pump housing.

My pump in my water jetted bathtub does not turn on anymore. It's 13 years old so I'm looking for a replacement, but can't seem to find a match. It says It's an AO Smith f48r24c83. I have found similar pumps, but with no impeller attached or the wrong frame number (56Z).
 Reply

InyoPools Product Specialist  Posted: 1/3/2019 

You may only be finding motors because the f48r24c83 is the model number for just the motor. To find the correct replacement pump, find the model or part number on the pump housing (the round housing the motor bolts to.)

Ok I tried looking up the other number, American Acrylic and Injection CRBT 07-1AA, but it seems obsolete now with few other details.
 Reply

InyoPools Product Specialist  Posted: 1/10/2019 

I tried searching on my end, looking through different distributors, but there really isn't anything. I found a parts list, but like you said everything was obsolete. When I search for the CRBT 07-1AA, I received several results for the CRBT 07-1AE, but there was no info on the differences or compaitibily between the two.

Hello Rlaeche - The majority of pool motors are made by Century. The squealing bearings were caused by water running down the motor shaft. They may have reused your old shaft seal or used an inferior seal. We'd recommend using a salt water or heavy-duty shaft seal. Next time you replace the motor, make sure you get a shaft seal with viton rubber and a carbon ring.

Last year we replaced both of our pool motors (one runs the pump and the other the pool sweeper). Now the motor for the pump is making a high pitch squealing noise and the pool company said the bearings are going out. It of course is not under warranty, we were one month past a year. I questioned the pool service company and they stated all pool motors are the same and this happens........ We have had our pool for over 20 years and have only have to replace the motors one time previously. My question is are there different quality levels of pool motors or is what that company said true, and they are all the same and made by one company?

Hello Chris - The direct replacement for your 0-177896-22 motor is model B849. That is a 1.5HP full rated single speed motor. The total HP (SFxHP) of that motor is 2.25. A more energy efficient option is model ECM27SQU. The ECM27SQU is a 2.7 total HP variable speed motor. The complete pump we'd recommend is PureLine model PL2606. That is a 2.7 total HP variable speed pump with 2" ports.

I have a Century pump with AO Smith motor 0-177896-22 pumping 3 waterfalls in my pool. It has shorted out. I am looking to replace the motor and/or entire pump. I know the cheapest method is to replace the motor. I would like to save on energy if possible. What other motors/pumps should I consider?
 Reply

 Posted: 8/24/2018 

Hello Mel - The single speed replacement motor for your C48L2N134B1 is part number UST1152. I believe the Energy Star ratings are only applied to complete pumps. If you go with a complete pump, we recommend the PureLine Prime model PL2605. The Curve A Energy Factor is 18.07.

 Posted: 8/24/2018 

I have an AOSmith model C48L2N134B1, 1.5 HP, 1.1KW, 115/230 Volt, 3450RPM that has gone bad. Looking for what to use as a replacement, single or VS. Can you provide suggestions? If VS, my utility is offering rebates for Energy Star rated with an Energy factor of 3.8 or greater. Thanks

must - The GOKIT you need is identified by the model of the pump you are placing the new motor in not the motor. For example, GOKIT77 is the Tune Up Kit for the Jandy JHP + JHPU Pump Series. Type in your pump model and you should find your GOKIT in the parts list.

Thank you for your very informative reply. I have checked and space around the current motor is sufficient for the additional motor length of 1.05" and the mounting holes are of same distance so it should match and install easily I assume. My only question before placing the order for B654 motor...does tune up kit GOKIT77 matches/is required to do the job correctly? Is there a different kit for b654? I want to place the order for all parts i need so the job can be done effectively and efficiently :-) Thanks
 Reply

InyoPools Product Specialist  Posted: 8/14/2017 

must - The B654 would be the standard energy efficient replacement for your failing B128 motor. UCT1152 might also work but it is built with the 5 5/8” lamination, and the B654 uses the 6 ½” lamination. The B654 is slightly more efficient and would be the one to use if the existing motor has failed. Check your spacing. It looks like the B654 is an inch longer. I would recommend an EE motor for Dallas. And we do not get involved with installations so have no data on that process.
