Joe,
A screaming bearing on those motor many times only means the bearing is dried out. Try dripping a
few drops of a heavy motor oil into the well that is at the base of the gear on top of the motor. With luck this heavy oil will soften the dried lube in the bearing after running it for a few minutes. I have used this method several times and have never had to replace the bearing.

But for the most part the old girl is up and running again. One more rescued machine.
