I need to replace my pump motor and I have both an SQ1202 and a B843, what is the difference if any?
Hi, Roger. The Frame Size and efficiency ratings of the motors are different. The SQ1202 has a 48Y frame and uses 11.2 amps and the B843 motor has a 56Y frame and uses 10.2 amps but both motors have the same Total HP of 2.6.
hello i have a whisperflo 2hp motor number 177452 and im looking to replace it with this motor will it direct fit or do i need a different motor also is the wiring included with the new motor please email me Thank you for your time JD
JD, The B843 motor will be an exact replacement. The motor does not come with a cord, you would use the existing one if still in good shape or purchase a new one. if you have the WhisperFlo pump, I recommend buying the GOKIT32 so you can change the seals when you replace the motor.

Is this the energy efficient version of A.O. Smith 2 HP, 56Y Frame, Up-Rate Motor - B855? There is no information on our current motor but I know the model number on the pump is WF -28 C (Purex triton WhisperFlo) The only thing I can tell is that the attached aftermarket pump is 2.0 HP. Would this work with my pump and is it energy efficient?
Hi, Destiny. The EE option to the B855 motor would be the B842 motor. I will have the same THP as the B855 motor nut uses less energy.

I am wiring the new motor in using the existing 220V setup: 12 ga. copper wires from a previous very old motor. The green is ground but the other 2 are red and purple which are the "hot" wires. Does it matter which ones I put onto the L1 or L2 terminals? The old motor did not have a L1 or L2 labeled terminal block.
Good afternoon Jim, The green is your ground and that will go to the green screw. The other two wires are your hot leads and they will go to L1 and L2 doesn't which one's there both hot with the same voltage.

Neal, Are you referring to parts for the pump or parts for the motor?
Do gaskets come with the pump or must I order them separately ?
Hi James, Gaskets for the pump does not come with the motor, you will have to purchase them separately. You will also have to know the manufacture and model of the pump housing that the motor connects to in order to locate the correct pump gaskets, o-rings and shaft seal.
I have the A.O. Smith Motor 7-193995-07, which all the specs are the same on the motor that I am looking at, but my motor has --- HP instead of saying what the HP is. The Jandy Stealth pool pump says 2.5 hp. Does this motor work with my pool pump, as it is a 2.0 HP motor?
Hi Lynn, This B843 motor will be the correct replacement motor for p/n 7-193995-07 that is mounted to your Jandy Stealth pump. This is a "full rate" motor, what that means is the it's rated a 2 HP but has a service factor of 1.3. When you multiply the rated hp by the service factor you get the total hp of that motor, which would be 2.6 HP.
How can I specify the almond color? Is there a different part number?
The almond colored motor is Pentair part number 071316S. Please Note: The lead time for the almond colored motor is 2-3 weeks.
I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?
Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.
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.

My family and I recently moved into a house that has a pool that has not been used in about 20 years. Of course the pool had a number of issues after sitting so long, one of which was a bad motor. Since all of the pool's equipment sits out in the open, most of the identifying marks were weather faded and unreadable. Therefore, I contacted a customer service rep at INYO who was able to provide all of the correct part numbers, based on my descriptions of the parts. The rep also recommended a couple of videos that would be the most applicable to my situation, and after viewing those, I was able to replace the pump motor and perform a tune up on the pump in about an hour. One of the most helpful things the rep told me was that the motor comes without any accompanying equipment, including a power cord. I found this very helpful because it clued me in to the fact that I also needed to order all the extra items I needed, rather than finding out when I opened the box. This saved me the trouble of having to place a second order, and then having to wait a couple of more days for those parts to come in. At any rate, I wired up the motor according to the included wiring diagram and followed the information I obtained from the videos on everything else and when I was done, the whole thing fired right up and has been running without any problems ever since.
