What is Service Factor?
Reply
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?
Reply
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?
Reply
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?

If this motor is installed without the two speed switch, and hooked up to an existing single speed timer will it function as a single speed motor?
Reply
Yes, without the switch it will stay at high speed the whole time.

(4 out of 5 stars) Great replacement motor
Reviewed By: JTM1 from Houston, TX ()
Pros: Price, availability
Cons: packaging, limited knowledge of customer service
Had my motor go out on me recently-called over to Warehouse Pool Supply (now taken over by Leslie's). First they told me they didnt sell the motor I needed (even though I had purchased one from Warehouse 3 years prior). They were generally unhelpful and their price would have been $330 higher (plus tax) over Inyopools price. They were only interested in trying to sell me a new variable speed pump and chemicals that I didn't need. Inyopools had the exact motor I was replacing, it was in stock and 3 day ground shipping was free. I was able to manage my pool without the main filter pump to allow me to wait to install it. It arrived just as promised and was an exact fit up..My pool was back up and running perfectly a couple hours later.
