If it was up to me, YES.So, what do you figure? Is this motor worth restoring or not?
Will you use that motor in 5 years?
Keep the motor. No brainer
Open up the old motor and change out the bearings as a learning exercise. The. New bearings on. 1/2 hp to 3/4 motor should be about $20. - great learning![]()

Hey Craig,
if you push, pull or twist the outer casing on those bearings do you notice any movement between the outer and inner race? When you rotated them, any gritty or harder to turn spots? If you have cleaned them out, will they spin and go for a long time or just a revolution or two and then stop? Any signs of corrosion or pitting on the balls? Any signs of the bearing spinning in the outer housing?
Recommend replacing them with sealed bearings. So on the race of the bearing will be some numbers - when you get new bearings ask for xxxx 2RS for example.
make sure to gently clean off the centrifugal switch contacts before re-assembly.
Notice that your motor is open to atmosphere (the slots on the back plate). That would be a typical drip proof type motor - that fan on the shaft draws air across for cooling. It will also draw oil and swarf and other crap. - if you recall from my lathe post I removed a bunch of swarf and a drywall screw from the old motor. I now have a shield that keeps the swarf at bay but allows proper air flow.
Craig, while you have the motor apart for new bearings, I would address the rotor shaft as well. That is some chewed-up, sad looking piece...
pulleys will fit better as well. Turn it between centers on your lathe to clean up all the chowder marks. You will either have to sleeve the pulley or the shaft to make up the difference.
