I have a 2.5 HP Pentair pump that will not start on its own. It hums and if I turn the shaft with a wrench eventually it will slowly turn and start, runs fine from that point on. I have cleaned the impellor, very little debris. I need to repeat process everyday to get the pump going. After reading many threads on this issue, I suspect, bad capacitor, however, should the shaft require a wrench to turn? I cannot turn the shaft with my hand. Is it possible motor bearings are shot? If motor capacitor is problem, where can I find the part? Pentair only sells as an assembly. Thanks for any thoughts/guidance!!

Find a electric motor shop in your area. Depending how old your pump is you might be looking at a new one. There are motor shops out there that a reasonable though.
The bearings are failing. Otherwise you would be able to easily turn the shaft by hand. You need to replace the bearings, or have someone else do it for you. As maxepr1, a motor shop will do this quickly and affordably.
