HELP Removing stuck driven comet pulley

[Hansona15]

Jackshaft bearings were bad on my vintage Trike and wore out the jack shaft. After several attempts of while trying remove on the trike. I cut the shaft in half( it was be anyways) removed everything off the driven including the spring and slide. The pulley is seized on the shaft I have applied moderate heat and some pressure in the press. It appears that everything that is being used to applies pressure is iron and strong. Trying to avoid breaking or damaging anything. Is it safe to assume I can wrench down on my 6 ton press and pop the shaft loose?

If the key rolled it might never come off. Drivers are cheap enough. I’d go to town with some heat and just push on it.

What do mean by rolled key?

What do mean by rolled key?

the key way that holds the driven in place on the jack shaft started to roll over and wedges into the key slot. So instead of sitting flat it’s sitting more towards a diamond shape in the slot.

That sounds like something I would be able to see. Key way looks straight with the naked eye. Thoughts?

Just popped the key way out with a starting punch!!

Might as well turn loose with your press. At this point what have you got to lose? If the shaft comes out, great. If it doesn't then you are buying a new driven. As it sits right now, pretty useless. BTW, nice press, very handy tool.

Thanks, I threw it in the freezer for about an hour pulled it out hit it with the torch. Put it on the bench vise to give it some good vibrations striking the back side of the jack shaft. She popped loose and I pushed her the rest of the with the press. The press takes up room on the bench but comes in handy quite often.
