Hi, just curious when you use a bronze gear on a billet roller cam, and a bronze sleeve to support the gear, what is supposed to keep them from wearing against each other?
Oil
I ran one(Milidon gear on a Pioneer bushing) on my old pump gas car with no wear problems for over 3000 miles and hundreds of 1/4 and 1/8 mile races
I recently had a Mopar brand oil pump drive with bronze gear wobble horribly in the block, It was bad enough to make the distributor move around when running or on the starter
Bad parts are out there so make sure yours is not one of them
