OK, I'm sure this is a novice question for this forum.
I'm working on an engine, and I need to remove a woodruff key to pull a seal off a shaft. I've worked at prying it out and have avoided the hammer for fear of damaging the shaft bearings. I know they are installed with a slight interference fit, but this thing won't budge. It's a stainless shaft and stainless key.
So what's the trick to removing woodruff keys? I've thought of shrinking it with dry ice or liquid nitrogen, although I have no idea where I'd get liquid nitrogen.
