I am not sure how yours is set up, but try some WD-40, heat or my favorite, if you are able to apply pressure (clamp or something) and give it a good whack that usually works.

Once you have the WD-40 and heat applied a few good sharp blows on the puch should bring it out.

I agree with them, heat usually does a great job with anything stuck.

Yes, the wax thing works! Plus, if there is any give at all in the shaft the pin is in, that dissolves 1/2 or more of the strike force. If you can somehow back up the shaft or whatever part with a block of sorts, it will greatly increase the force to the pin.

I have some of those at work that I have to remove from centrifuge drive motor shafts. The company that makes the machines supplied a press that fits over the shaft and you screw fine thread bolts into it to push the pins out. It takes a lot of force to remove those if they are stuck. With a press all the force is going into pushing out the pin. As Daniel said above, you need to keep the shaft from moving so all the force goes into moving the pin. Heat can make a huge difference. A thermal cycle or 2 will sometimes break the bond and a stuck pin will come out with a more normal amount of force. Good luck with them.

What ever you do, make sure your punch is sharp, meaning good square face with sharp edges and the proper size. You dont want mushroom over the pin or bend it.

:ditto: And, that's one set of tools you don't want to go cheap on. Walk away from the made in china cheap
chisel/punch set. Just a waste of money.

Interesting...What exactlly is happening here?
Does the liquid wax work into the very tight spots to loosen them, or does the wax dissolve the rust?

Wax wicks its way in to lube the pin or what ever it is you want to free up.

When I cause or find one with a mushroomed head I use a cut off wheel in a die grinder or a hand held disc grinder to cut it off flush with the shaft.

Wish i had one of those when I was doing that regularly. You should have seen some of the ways we came up with to get them out.

It was specifically for a Beckman Spinchron or GS6 centrifuge. The first one they sent stripped out the threads in the press after only a couple of uses. The next one was larger with more thread length and hardened. Most of those machines are retired now but I've still got a few in use.
