This thing is in there tighter than Dick's hatband, and it's dented so I would like to remove it to straighten it out.  I just haven't figured out how to do so without harming it further.

The only thing I would think of (coming from someone who hasn't done this) is to squirt some penetrating oil in the crevices on the inside and wait, and wait, to see if it will weaken and slide out. Maybe heat on the surrounding casting to expand it? Last resort would probably be the use of a drift punch the diameter of the cap.

Jamie,
I used a single sided razorblade taped into the seam to start it moving, next I use a thicker knife to open it up more... then heat gun on the cap only and a pot holder to grab and twist. worked for me on a BYM

Thanks Alec, you think like I do. I have already sprayed it down with Aero Kroil, and expansion with heat is always on my radar. In this case there is no real option to punch it out, as you would have to work through the bearing carrier and with the amount of force required to loosen it would punch a hole in the cap before it dislodged it. I'd be attacking a 1" cap with a 3/32" punch pin and a hammer.

William,

That sounds very workable, thanks for the advice.

Try this. Heat the cap with a heat gun to expand it slightly, then insert a WOOD dowel from the inside, through the bearing, and gently tap the dowel with a hammer. Sand the tip of the dowel to match the shape of the cap so you don’t distort it.
That’s how I remove them. They usually pop right off.

Thanks Lane. Yours, as well as all of the other responses I received, line up with what I think are good practices in general. I certainly appreciate all of the help.

Pop it off with a dowel from the back like Lane said, I've never even had to use heat. One swift hit with a hammer will pop it off without any damage

I’ve destroyed two of these because I thought I was crazy for asking something like this. Now I really wish I would have just asked so I wasn’t having to dimantle every old GE motor I find in search of these caps haha!
