I have a Hayward Super Pump that's maybe 5-7 years old. It didn't sound so bad last year, but after this really cold winter (which damaged various pipes around my house), it sounds rough now and has small amounts of air trickling in the return pipes of the pool since opening it (as well as air/cavitation in the forward area of the pump.)
So after reading a bit, I opened it up to check for debris in the impeller area and found basically none. Impeller and diffuser are in good shape.
The shaft spins freely about 90% of the time, but does seem to catch/slow down a bit every so often, like maybe the bearings aren't so good.
So since I put it back together, I noticed a leak under the impeller region. I can't be certain it wasn't there before because the cement it sets on was wet when I first noticed the smoke and smell. Maybe the leak was there all along or maybe I mucked it up.
So what is the diagnosis, and what should I do that isn't too hard or too expensive? Is it the bearings, the seal, and do you think the motor is OK enough to refurb it (ie. is the sound and smoke coming from the bearings and the added stress to the motor) or should I just get the whole back half replaced?
Need to order something soon before it all goes to pot.
