Emerson Air Compressor Rear Bell Removal

[asallwey]

My air compressor motor hummms. I put new caps on but it won't start, just hums. So I'm trying to pull the rear end bell to check the switch and clutch. I pulled the 4 bolts and was able to move the bell about 1/2". It will wiggle L-R, but won't come off. I tried tapping on it with my dead blow but it doesn't seem to move. It seems like something is really holding it, but I don't see anything. Can't bring myself to just wale on it yet. The motor is 10-15 y/o, and was outside under cover. It ran for a number of years, but not the last couple. But after I moved it inside 2 weeks ago it did pump up, but wouldn't restart. Then with no air it still wouldn't restart, just hum.

Any suggest for pulling the bell off?

Does the rotor on the motor spin freely? Should be able to remove a bell end .

It did before I started moving the rear bell. I have to remove the pulley as I noticed it moved in about what the rear move out. I suppose the shaft is galled into the rear bell. Should know later today.

Removed the pulley (nice challenge), then the front bell. The rotor / rear bell will move about 1/2", then feels stuck. Not ready to force it yet, but I will keep poking at it.
