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.

Can you direct me to the proper hi low switch for this motor?
Reply
Unfortunately the manufacturer does not offer the switch for the 2 speed 220v motors any longer. If you already have a 220 volt timer (on/off) you would need an Intermatic T106R to switch from high to low speed. If you do not have a timer currently you would need the T10604R which is a 220v on/off timer and a high/low timer.

Which the tune-up kit is the correct one for WATERWAY 48F Executive Pump, 2-speed, 4.5HP, 230Volt, 12.0A/3.5A - 3421821-1A ?

Hi Danny, There is not a Tune Up Kit for the Waterway Executive 48 Pump, you will have to purchase the Shaft Seal (PSR-1000) and Volute O-ring (805-0261) separately.

I have the older version of this pump, the Emerson T55MWCCE-1208. What capacitors (start and running) can I order from you to replace the ones I have. After reading on your web site here it sounds like I have a bad capacitor.
Thanks
Tom

The bearings we carry are for Century/A.O. Smith motors not Emerson motors. The BN62 would be the replacement motor for that motor though.
