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.

Hello Stan. The A.O. Smith 3/4 HP E.E. Square Flange Full Rate Motor is an exact replacement fit for the Sta-Rite Max-E-Pro 3/4 HP Full Rate Energy Efficient, Model P6E6D-205L. When replacing the motor, we strongly recommend replacing the Shaft Seal. If you would like to replace all your pump seals, we have the Tune Up Kit Sta-Rite Max-E-Pro available as well.

What shaft seal do I need? I'm replacing an A.O. Smith motor (QC1072) that is coupled to a WhisperFlo Model WFE-3.
Thanks

The correct shaft seal you would need is the PENTAIR SHAFT SEAL ASSEMBLY OEM (071734S) or the Generic Seal, Pump 1000 (psr 1000). The first is the manufacturer's version, the latter is the generic.

Hit the old motor capacitor with a hammer a couple times, then ordered an identical replacement motor.
Received in a good amount of time. Unhooked the old, connected the new, and checked my wiring, hit the power switch and, drat, it hummed and smoked. Power off, Contacted INYO support, they suggested a few things. But seriously, it turned fine via a screwdriver at the end of the motor... Well, took it all apart and put it back together again. I swear, same as before, but this time it powered on it started right up and purred nice and quiet. That was over 2 months ago. Still running nice and quiet. Thanks!

Purrs and starts up like it's supposed to. This was an exact replacement of my previous motor that ran for 7 years. In 2004 I bought a Sta-Rite Max-E-Glas Pump, High Head, EE, Full Rated, 3/4 HP, 115/230v (PE5D-181L). In May of 2013 I bought a new motor: A.O. Smith 3/4 HP E.E. Square Flange Full Rate Motor (QC1072), 5321-1 (AOSQC1072) So, now, I hope to get at least another 7 years out of this one. 10 would be nice. Working great after the first 2 months.

Excellent replacement motor fit perfect. Arrived in very quick time. perfect! It was not clear to me that the "Go Kit" would be included. I thought I read it may be shipped from another vendor and arrive at a different time. Tracking order was a good benefit also.
