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.

My pump is a sta rite #P2RA E(E MAYBE A 5) 1246 code #1L926. What motor is required?

Hello Tony - Your model number did not bring up a match. The USQ1152 would be the correct motor for the P2RA5F-182L.

1) Turn breaker off and remove old motor from pump housing.
2) I had excessive wear on my diffuser and decided to change it out since I was changing the motor.
3) replace all O- rings and shaft seals.
4) Install new motor and ensure all nuts/screws are tightened to manufactures specifications.
5) Ensure wiring is correct, for voltage as old motor- mine was 220 volts so I wired it accordingly.
6) once everything is installed, turn breaker on and ensure there are no leaks.

Very easy procedure just many steps as you don’t want to rush through it. Make sure you don’t lose any of the washers or nuts and bolts. The new motor uses your existing hardware. Great product and great company with fast shipping. Will buy my products from them in the future.

After confirming the correct replacement frame and horsepower requirements with INYO Pool Products, the correct motor arrived quickly. In my case, it was a simple break-down of the components (after deenergizing the circuit at the breaker panel); removing the motor, impeller, and diffuser from the pump housing using basic hand tools. I was careful to keep track of all fasteners and where they would reattach. It was simply a matter of attaching the new motor to the existing frame and reattaching the impeller and diffuser in the reverse order. From the external electrical disconnect box I replaced the water-tite flex conduit and connected power to the new motor, following the enclosed diagram. Once all connections were made and confirmed that Allen fasteners were tightened on the pump, I reset the breaker and turned the pump on using the external disconnect switch. The pump is now working better than ever.

(5 out of 5 stars) Excellent Pump Moter Replacement
Reviewed By: PoJo from Clarence, NY ()
Pros: Awesome fit - excellent replacement
Cons: none
Tip to get the impeller off the old pump moter: use a 7/16" open ended wrench - it slides in near the capacitor on the electrical side... rotate the impeller until the wrench slides into place at the end of the shaft and then one person holds the motor and the wrench while a 2nd person loosens the impeller off with bare hands by turning the impeller counter clock-wise.
