I assume you removed the distributor gear to disassemble it? Did you have to use any sort of tool to remove or install it? I have a junkyard remote TFI distributor I recently acquired and that cam gear won't budge.
i actually didn’t pull the gear. I mostly focused on the top end just for the sake of cleaning/painting. The gear and shaft got a good cleaning but stayed intact for the most part. I didn’t really have much concern with regards to the bearings inside.
I mostly didn’t touch it due to horror stories I’ve heard with that gear. I already busted my alternator fiddling with it
