I know that tension roll pins are normally larger than the hole they are to driven into, and the spring tension holds them in place. They also come in longitudinally slotted (split) and spiral wound.
Theoretically you should use specifically designed roll pin punches for removal and/or installation. They have a small nipple or tit on the end.
My question is since tension roll pins are hollow doesn't the nipple or tit tend to expand them, when the punch is struck with a hammer? The method seems counterintuitive to me.
Google wasn't any help, or I asked wrong.
