Okay, I finally took the electric motor (3/4 hp, capacitor start) off the
cement mixer. This is the motor that got flooded under water for about a
day or two (about 4 months ago).

Shaft will not turn. What's my next step? Tap on it with a soft mallet?
Try to take the end caps off? Move the shaft axially?

If you've done this, please advise. If you think it's a lost cause, tell
me.

Thanks, Ivan Vegvary
