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.

Yes, this is the correct replacement motor for your pump. You will also need a Jandy Stealth Shaft Seal when you replace your motor. We put together this Video on How to Replace a Pool Pump Motor which you may find helpful when you tackle this project.
