When I was restoring VoM record player, the shaft of the large sprocket was frozen shut. I could not rotate it with anything, and using the sprocket itself as a lever mad the sprocket rotate around the flared shaft it was secured on.

I used an immense amount of heat by my Milwaukee gun. And then a hammer to knock it out. It took a very serious effort. And the stuff that held it....it was like supercement. No glue could match it.

Heat, heat and then some more heat. As long as you don't melt it.
