shot peening a distributor gear for a roller camshaft

Yes to removing the gear from shaft.
However, the pin is a pain to remove at least
for my elderly hands.

I do not think shot peening would do the job on the gear.

Did certain years have pins, to be able to remove the gear. The two that I have do not have a pin, that I can see. Anyway to tell if they may or may not be melonized?

Maybe a lot of heat and a press?
