I have a Powermatic 66 from the early 90’s. Today I started it up and I tripped the circuit. Never happened before. However, once I fixed the breaker I tried to turn on the saw, it did not move but shimmied. I noticed that the blade and\or motor wanted to move but it wouldn’t get moving and just hummed. I checked the belts and they are fine. Do any of you have an idea on what is wrong. Hopefully the motor is fine!

Take the belts off and see if the motor will start with no load.

Likely a bad capacitor. Sometimes a motor with a capacitor on its
last legs will get going if you spin the sheave by hand. No big
deal to live with in a lathe but for a table saw no good. Capacitors
aren’t expensive.

Loren gives good advice. The other thing that may have happened is that the centrifugal switch that disengages the run windings and reconnects the start windings may have stuck in the run position.

Yes and yes on the above advice. Been there on both accounts but not the same machine.

Leave the Powermatic on the curb and I will be by to pick it up. Problem solved.
