I have a A.O. Smith SP1605-Z-1-MXBX Motor. At least that is what the label says. It is for a Hayward Max-Flow pool pump and was purchased in 2004. I need to replace the sealed bearing closest to pump assembly. I have measured this bearing at OD 36.5mm, ID 13.5mm and Thickness 8.5mm. I can't seem to find a bearing remotely close to these dimensions. The motor is a 3/4HP SF 1.0. Help.

Hi. ,I have a A.O. Smith PB4-60 Booster Pump and will be replacing the front and rear Motor bearings, do I need to go ahead and replace the shaft seals and rings while I am at it? Please advise the correct part numbers for this repair. Many Thanks

Inyo Answer

Answered on 11/03/2015 by Product Specialist Joe S.

Hello Marcia, the 203 bearing will be used in front and back of this motor. It is wise to change the shaft seal and all orings for the pump. Here is the link to the Polaris Booster Pump Parts

I have an AO Smith 1hp pump Model C48K2N143B1. I'm replacing the bearings and have so far pulled out the rear bearing. The bearing model # is 6203RSNCS. I can't seem to find this specific bearing. Will the front bearing be the same as well?

Inyo Answer

Answered on 10/09/2015 by Product Specialist Hector F.

Yes the front bearing will be the same for this motor and is the 5270-31.

I have a Hayward pump, I replaced the motor a few years ago with US motors 1hp for a In ground pool. I have a loud screaming noise and I believe I need to replace the bearings. I work on 40+ hp pumps at work, just never my pool pump. Curious if both bearings are 6203 ?

Hi Tim, We would need to know the model, part number of the motor or the part number off of the bearing that you have in order get you the correct replacement.

I have an AO Smith Centurion switchless, 1 HP pool pump/motor with a label that reads Sta-Rite #168452, model #PHK2RA6E-102L, self priming serial #001J09L. I need a replacement bearing and seal kit. Can you help?

Answered on 06/07/2015 by Product Specialist Lennox H.

Dan, Unfortunately the only way that we can find out what bearing is required for this motor is for you to take the motor apart and get the numbers off of the bearings.

   (5 out of 5 Stars) It was just what we needed to repair our pool pump.

The part was the right one and now our pump is much quieter. The shipping was faster then I thought it would be. It came in 3 days.
