There was a guy I know who once pressed a gear on a cam with out
heating it Or useing a bolt. The gear cam off in a Very short time. I to once had this issue Back in the early 80s and The Motor never even seen 100 miles before the gear cam off. If a Alum gear was used and Reinstalled onto another cam The Gear can walk off the cam In No time Flat.
I have also known guys to Just Heat the gear and Freeze the cam
and get away with it. BUT this is not the case when Reuseing a Alum gear.espcaily if the Gear has not been heated. What happens is the gear Is shaved by the Cam. and it now becomes a loose fit.
God doesn't like ugly.
