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?

I have a Hayward super pump rated at 2.0 hp. It is too powerful for my filter. Can I switch motors to step down the pressure I am getting from the pump?

Hi Robert, You could step down motor's but you would just need to make sure that you replace your impeller with the same HP as the new motor. You may view the Hayward Super Pump Impeller's on our Hayward Super Pump Parts Breakdown Page.

My original water feature pump, 16 years old & exposed to elements, stopped working and figured the motor is toast...and it is.
It is an A.O. Smith, Model # K48K2N104, Ser 8F02.
This motor looks like it may replace this motor.
Am I correct?

Yes, this is a correct replacement motor for your model K48K2N104 motor.

The direct replacement would be the Century Motors B227SE. Century 3/4 HP Up Rate Motor - B227SE Any additional parts related to the motor change would be specific to the pump manufacturer/model.
