I'm in the same boat as you right now. I have the same motor on my Hayward superpump. I'd like to try replacing the bearing, but I can't seem to find what the bearing size/type that I need to replace.

I talked to a pool guy who has done some repairs for me, and he said he usually just replaces the motors on the pump when the bearing goes bad.

That seems like a waste to me, but I might have to do that unless I can find out what the bearing is that I need.

If I find anything out I will let you know.
