I replaced my old motor with a new on of these. It hums and then kicks on after about 5 seconds. COuld it be the capacitor already since its brand new?
Replacing a B127 (part# 0-164302-24) motor type CX frame S56J. Your video on replacing pool motors says to short the capacitor. Tech (Lennox) says not to worry about it.
Just curious as to why you don't have to discharge the capacitor. Is it strictly for this motor?
Apologies if overkill but I just trying to cover all my bases. Thanks!
Hi, Mike. Due to the design of the B127 motor, you do not need to discharge the capacitor.
I am looking to replace a B127 (part# 0-164302-24) motor type CX frame S56J. Do I need to short out the capacitors to remove the electrical wires?
Hi, Mike. You do not need to short out the capacitor when replacing the complete motor.
Will this pump replace my current pump?
See attached picture...
Also, I reached inside the filter basket to see if the impeller felt okay. I can move the impeller with my fingers and it seemed to wiggle around a bit. Is that normal or could I have an issue with the entire pump not just the motor?
This B127 is the drop-in replacement for your current B127. As for the impeller, there is not much I can tell from that description. The best way to figure out of a part in the pump is broken, is to open it up and inspect it.
I am looking to replace a B127 (part# 0-164302-24) motor type CX frame S56J (attached spec). is this the correct replacement?
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?
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)
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?
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?
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?
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?
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.

received motor within a week of ordering, assembled it into my existing pump head and everything fit together with no problems, I have not had time yet to finish wiring it so don’t know how it runs as of now but so far so good.
