Removing Wheel cup/spacer from 1950's C-Man grinder

[87Pomona]

I began to break down my 1950's Craftsman grinder today for th resto and I ran into a small problem. The wheel cup/spacers are I believe stuck on the shaft.

Has anyone ever ran into this problem? How did you manage to remove them?

A couple of pictures of the cups/spacers

You could get it off with a gear puller but you want to be care full not to break it. Soak it in penetrating oil to loosen it up a little.

I had the same problem on a 3 phase grinder, very close fit on the cup. I think I tapped the steel cup with a hammer and walked it down.

Wow I have never seen lights built into the guards before!

a good penetrating oil. After it soaks, tap with a rubber mallet carefully around the cup while gently using a pry bar behind it to walk it off.

X2, that's awesome!

This is what I did with my buddies 30's B+D model, came right apart after a few minutes.

The cup looks to be made from aluminum. If so, try applying some heat from a heat gun. The cup will expand more than the steel shaft and should loosen right up.

Well oil/rubber mallet and heat havent worked. Let it soak in PB blaster overnight.

The cup spins freely from the spindle, maybe this early model grinder had a different kind of cup setup?

I forgot to mention when I place a prybar behind the cup and push, it'll move the cup and spindle forward. As soon as I let go it'll move back, kinda like spring action.

^^^ What he said. With a little luck maybe even a cheap HF gear puller could be up to the job.

Use heat and penetrant then use the gear puller but go easy. The key to using a gear puller is to put moderate pressure on the screw and then give it a tap. Tighten a little more and then another tap.

I would not pry it!! That spring pressure could be the centrifical switch and you could break that assembly trying to pry the spindle to the side.
