View Full Version : Pump Motor damaged during bearing replacement

I have a Hayward FloMax pump driven by a 1HP AO Smith motor. [ C48K2N143B1] While pulling the old bearings off, with a three fingered tool, believe it or not, I bent the threaded end of the rotor shaft. OK, when it wouldn't come off I whacked it. It is very slight but the impeller is not perfectly square in the new seal. Wobble does not interfere with the housing but still not a true fit. I have not tried it but believe the seal will not function properly and/or be damaged. I have searched locally and on the internet for a replacement rotor but can not find one. The motor runs as new. [with out the pump attached] I hate to spring for $285.00 if there is a new or used part available. It is not a wound rotor. Solid as an anvil. Am I the only dummy who has done this?:o

Any suggestions appreciated.

I will answer my own question, then go on to better things. According to a, very experienced, local pool man, there is no such thing as a replacement rotor unless you get lucky and find someone replacing an entire motor that can be salvaged. Additionally, he recommends that it is not economically advantageous to even try to repair these motors. It seems that one will invariably have some sort of problem, such as I, and after the cost of new parts, already spent, you more than likely will end up buying a new motor.

For what it's worth; I found the shaft was not bent but the threads were damaged. I put a die to the threads and may be out of trouble.

Thanks for your attention,Bob

You aren't the first to bend a shaft and you won't be the last to bite the bullet and buy new.

Thanks for the comment. It did, somewhat, restore my confidence. Thought I had lost it.
