Frozen shaft in model E cylinder machine

[ambrola]

First off, you have to pull the Dog out. Then you can remove the pulleys or at least see the end of the shaft. I would remove the dog, then try the brass punch and knock it out? The Dog is marked in red. You can just grab it with some pliers and pull it out.

The mandrel shaft needs to be pulled out first, before the rest of it can come apart.
This center bearing gear (you point out)will not pull out. It is not like the end support bearing on a model A or B.
It is a support with a gear and pivot / bearing on the end. The mandrel shaft must be pulled out a couple of inches before the belt pulley and clutch can be removed.
Then the support, gear, pivot(one piece) is pushed in, to be removed.
After removing all set and regular screws, the next step is to get the mandrel shaft out.

You are right Larry. I forgot which model we were working with. If he keeps turning the shaft, it should move enough to get it out. Last thing, put it in the freezer over night and see if that will shrink the pot metal a little. It has worked for me many times on stuck reproducers? After looking at the picture again, it looks like the pulleys should come off. Slide them up on the shaft and wiggle them around. They are hard to remove when everything is out of the way sometimes.

Success!!

Copious soaking with muriatic acid overnight had absolutely no effect. Time for brute force.

Scored the bearing in several places with the Dremel. Then went at it with a hammer & sharpened screwdriver until I managed to bust away most of it. Then back to wood block & hammer against visegrips until it sl-o-w-ly budged then finally came out.

Whew!

Thanks everybody for all your help and advice.

Next, miniature hacksaw blade to remove the rest of the bearing; then to Mr. Sitko to see about parts.
