What is Service Factor?

A  Answered on 1/11/2012 by InyoPools 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.

Why do I need to purchase a new shaft seal?

A  Answered on 1/12/2012 by InyoPools 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.

Why should I purchase a Tune Up Kit?

A  Answered on 1/12/2012 by InyoPools 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.

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?

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

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 will be buying this motor, but I don't see a go-kit for a 3/4 HP motor. What should I by??

A  Answered on 1/9/2015 by InyoPools Product Specialist Brian M.

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.

Old pump motor was getting very loud

Written on 6/10/2020 by Guest

Replacing the motor was pretty straightforward, 6 bolts attach motor assembly to the pump housing, and 4 bolts attach the motor to the motor assembly. The how to guide on inyopools cover's every detail and with the time to read that first it still doesn't take very long. Maybe 1.5 hours

Motor Stopped Working, needed to be replaced

Written on 7/3/2019 by Guest

I called Customer Service at INYP Pools and they helped me find the right replacement pump to order along with the correct gasket replacement kit. I received both and am happy to report that everything was installed correctly and now my pump works fine.

The only issue I did encounter was with the installation of the ceramic bushings. The bushing/washer included in the kit was generic and didn't appear to fit correctly. I ordered a OEM Pentair one and it fit properly. This was the first time I've done this type of repair and it'll be much easier the next time now that I know what I'm doing.
