I am using a Cloyes 9-3635X9 timing set in my 351W rebuild that is using the reconditioned factory crank. I am running into an issue where the gear that goes on the crank won’t go on all the way. I can get the gear slid on until it is about .25” past the end of the crank snout but that is as far as I can get. Tapping it on with a hammer doesn’t sound like a good idea and I was wondering if any one has any tricks. The factory set slid off without issue. I don’t think it is the keyway because when I get the gear slid on as far as I can by hand, I can turn the gear ever so slightly and feel it move up to the keyway in both directions. I can try heating up the gear to get it to go on, but I am concerned that if I need to make any adjustment when I degree my cam, I won’t be able to get it back off. Any ideas?
