MSD Pro billet distributor replacement for SBC Gear

racer913 · 08-18-2020, 03:49 PM

I'm replacing gear and roll pin on SBC, I was able to pull gear off by hand. Snug but not pressed on is this a pressed on fit to not completely rely on pin for strength ? New gear is on way so can't check new gear fit

thank you

Never seen a SBC dist. gear that was pressed on. Snug fit and the roll pin secures it.

X2--but they should not be real sloppy either --kind of a gentle tap with a SMALL rubber mallet to help it slide on--dont BEAT IT ON--just a little harder than hitting it with your fist--some go on real easy and some are "snug" --if need be try a scotchbrite pad to "polish" the shaft --dont go ballistic here

i.ve seen some manufactures offer .492 " & .500 " id sizes gears for chevs .. check what you have

also spend a dime and put in a new roll pin and gasket too-- then check your tooth engagement depth and make sure that the distributor has not bottoming out when you tighten the bolt that is too far down

Not to mention using the correct type of gear for the cam - plain old cast iron, melonized, bronze, composite all have different cam cores they are compatible with.

is there not a referance dot on the gear? can be installed either way?
