Stuck keystock on crankshaft

Anybody have tips for removing a stuck keystock on the engine crankshaft?

Update: a 3/16" pin punch and a hammer popped it off eventually.


Drill a hole if you can in the end, and use a slide hammer. Alternatively weld an old set of vice grips to it and use a slide hammer.

Some heat might work, but you might hurt the shaft if it’s too much and make it eccentric. I’ve used a tig welder to get a little heat into things before, maybe just tack across the top. I don’t know if a pencil tip torch would be too much.

A chisel might work from the end, angling up, but be super careful.

Woo! Good job!! Disregard above. :smiley:

I was going to suggest that, but I assumed you’d already tried it or you wouldn’t be posting the question, lol. :joy:

Haha to be fair, I had tried it! Trying it again and again and again is what worked.

When you reinstall the key and pump put some copper anti seize on the shaft, key, and groove. Will make it easier to remove everything next time.


Just an add-on question to this thread- if you are removing a pump and putting the exact same model pump back onto the engine, is it necessary to remove the keystock in this situation?
