I have a Nidec B625 3/4 hp pool cleaner motor that is leaking oil or grease out the back. Is this from the bearings and does that mean the bearings need to be replaced? Is this something that would be covered under the 1 year warranty? Also, is the capacitor something that would be covered under the 1 year warranty?
Yes, this is typically covered by the manufacturer as long as it falls under the manufacturer warranty parameters. You can view the warranty card here.
Can the capacitor be change on this motor hum but won't run
Hi. The Start Capacitor - BC-124 can be replaced if it's bad. A bad capacitor can cause the motor to hum but won't run.
Will this o-173840-23 interchange with a Jandi Part 7-193633-24 pool pump
Unfortunately no. One motor is not as strong and designed for a booster pump.
I too have this exact same problem: pump motor will run for a few seconds then it will cut off. If I don't cut power it will try to start up again in a minute but it will only power up for a few seconds then cuts off again. The pump is a Century A O Smith Part # 0-173840-23.... but I doubt it is wired wrong as it has been working for many years. If I order this motor does it include instructions on how to put it in the casing. I have never done this before. Thanks
Kurt, The motor does not come with instructions but this guide may help.

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.
(5 out of 5 stars) Easy replacement with the identical same motor.
Reviewed By: Buddy from Fort Worth, TX ()
INYO gave free delivery for the booster pump. The booster pump arrived before the anticipated delivery date. The pump is the identical pump which I was replacing. This made for an easy replacement. I would recommend INYO to my friends and family. I will definitely use INYO Pools in the future.
