I’m rebuilding the gripper assembly on a very dirty SP-20. The pins are jammed in the holes due to the previous owner’s habit of just shooting WD-40 around the pins instead of lubricating them with graphite powder or grease. I’ve tried pulling them out, but they seem glued in there. I don’t think bent pins are the problem, because every pin is affected. Any suggestions?

Yep. It worked exactly as advertised. Thanks for directing me to that link, Paul.
Alex’s idea worked wonders. I baked my gripper assembly for 10 minutes at 300, two times, and then tapped with a rubber mallet and the pins came out. The miracle of 2010 so far!
