I've got a Hayward RS 2000 pump with an AO Smith single speed, round flanged motor. Unfortunately, the motor was overheating, and when I opened it up, it seemed like the rear bearing was welded to the shaft, it was so stuck. Even using a set of bearing pullers, I just couldn't get the thing removed, and I think I did some damage to the threaded end of the motor while I was working on it, so I'm not sure the centrifugal switch will screw back in. So I'm looking for a new motor. Should I be looking at a direct HP replacement, or should I think about downgrading to a 1 HP?
