Re: Pump Issues
Usually you can get to the rotor by pulling the rear cover where the power line goes in. I'm thinking that if it were jammed bearings it would have popped the breaker. Did the thermal cutout in the motor trip? There usually is one that could be either a manual reset or one that closes again when it cools down.
When the motor is cool try putting power on it again. If the bearings or something else is preventing rotation you will hear a loud hum and after a few seconds the circuit breaker in the house should trip.
If you hear a low level hum then possibly the centrifugal starter switch contacts are crummy or the starting capacitor is open. Here's my reasoning.
If something is preventing rotation then the starting winding will be in the circuit and pulling a very high current. That would make the loud hum. If something in the starting circuit is open then only the running winding would be in the circuit drawing much less current but the motor wouldn't start. Eventually it would heat up and the thermal cutout would open. The most common problem is the centrifugal switch contacts getting crummy and not making contact. That switch is usually on the back end of the motor accessable when you remove the cover where the power line enters. That switch closes until a certain speed is reached then it opens.
Here's a link to a thread that gives more info.

I don't know how many times over the years that blasted switch has been the culprit and a simple cleaning with a small flat file or fine sandpaper has saved $$$.
Hope it's something simple.
