I have a Hayward TriStar 2-speed SP32152EE 1.5HP pump that has an AOSmith/Century motor on it, Motor is part# 7-K56AA14A04-05 (see image below). Pump is starting to whine pretty badly and I want to overhaul it if possible with bearings & seals but I can’t find the correct info for those parts. I did look in the INYO reference here but didn’t see it.
Can anyone tell me which parts I need?
Thanks!
FYI I contacted Century (RegalBeloit) and they couldn’t/wouldn’t provide the info. They told me to contact Hayward.
I contacted Hayward, and a very helpful guy named Scott replied almost immediately with:
The bearing size for the shaft end is 304 and the other side
is 203.
Below are the part numbers for the bearings and seals.
304 Bearing - Part Number 5270-36
203 Bearing - Part Number 5270-31
Tri-Star Seal Kit - Part Number GOKIT81
Unfortunately the Hayward guy was wrong. I decided to just pull them and measure them before ordering and I’m glad I did. They are both 203 17mm x 40mm x 12mm double sealed bearings. So from your store they are both the 203 Bearing.
So to reiterate, you need 2 each of the 203 17 x 40 x 12mm bearing for this motor part#.
Thank you for the feedback, Paul. There are cases where A.O. Smith/Century changed the bearings from year to year in the same motor. It is always a good idea to pull the bearings to confirm.
