can i get the large bearing on pump end of a p7-164302-24 motor ?
 Reply

A  Answered on 3/20/2017 by InyoPools Product Specialist Lennox H.

Hi, Ralph. The 304 Bearing is the bearing that is used on the shaft end and 203 Bearing on the opposite shaft end.

I have a Century Centurion (AO Smith) 7-164302-24 3/4 hp pool pump motor, serial number BW8-07, and I need bearings and shaft seal. Do you have those?
 Reply

A  Answered on 7/20/2016 by InyoPools Product Specialist Lennox H.

Hi Chandra, The 7-164302-23 motor uses the 203 Bearing (62032RS) one on either end. The shaft seals are specific to the pump housing, so we will need to know the model of that part.

?     Asked on 7/7/2016 by

The label on my Century Centurion motor is missing vital information. There is a part number but there are no CAT, HP or SF numbers. The part number is 7-193631-24. I found a matching motor using the 6 digit number in the middle. Does that mean it is an exact match or does the HP and SF still need to be identified? (the numbers were not obliterated in any way, they were not on the label to begin with) Thanks

Hi, Yes, this motor can be used as a replacement for the motor you have with p/n 7-193631-24.

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?
 Reply

A  Answered on 1/19/2012 by InyoPools Product Specialist Patrick P.

Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

Why should I purchase a Tune Up Kit?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

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.

Why do I need to purchase a new shaft seal?
 Reply

A  Answered on 1/12/2012 by InyoPools Product Specialist Patrick P.

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.

What is Service Factor?
 Reply

A  Answered on 1/11/2012 by InyoPools Product Specialist Patrick P.

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.

First turn off pump. Close filter and any connected lines. Turn circuit breaker off. Take picture of wiring for reference. Remove wiring and ground wire if installed. Remove four mount bolts then motor will be free.
