seems like all new cams today r not radioused on the gears to prevent whittling away the bronze teeth. i have experianced this for the last 10 years with my ols 480 inch hemi to todays 440. cant sell bronze gears if they r radiased to be compatible with them. but good for u.
That’s the onelike this 1..

OIL PUMP DRV SHAFT W/ TREATED STEEL GEAR
BIG BLOCK 1045 STEEL SHAFT W/ HARDENED TIP & TREATED STEEL GEAR
$178.95
We now offer the chemically treated (melonized) steel gear mounted on our custom made 1045 steel shaft for big block engines.
The "treated" iron gear is a lifetime gear that can be used with any cam. The shafts are made exclusively for us and are available separately by ordering part #6220. The shaft and gear are assembled and pinned here in our shop.
High volume, or high pressure oil pumps are not recommended as they accelerate wear on any cam gear and oil pump drive gear.
Any new (or cleaned) cam - roller, billet, cast, flat tappet, or what have you...cleaned means no residue from the old gear.
people R having this problem where as melonized gears R being made for these applications,,companys have gone so far as to make plastisied gears for roller cams, i have had this problem on no less than 4 differant blocks, 1 of them was a 67 hemi...seems the cam manf today dont radious the teeth like they did in previous years,,,the cam/bronze gear i pulled out of my hemi block from back in the day mated itself to the cam gear and never wore anymore since then....its not from bad factory machining location process's,,,,the last motor i had in my 1971 barracuda, i ysed the dremel tool on it, wore in to a certain depth and no more....trying to get away from that...looking to see what other people r doing.
yeah,,,,and did it help the narative.........meanings the same unless u have nothing to contribute but spell check.....
could be,,the older cam that came out of the motor mated itself to the gear and never wore more than that, i did touch the tops of the teeth with my dremel stone before i installed it (compo cams) so i will run it some more and keep an eye on it. its just that with every roller cam i have used in the last 10+ years i go thru the same thing. 1 was so bad i had to to pull the cam back out and radious the teeth because in a short period of time the gear was more than half gone! seems like the cam manf left out a final step in cam grinding these days ?
yes,,end play is set at .003. milodon gear drive full cover. comp cams roller with milodon bronze drive gear, with new replacement bronze shaft bushing.
only 1's without "excessive" wear were an older unit that came in 2 differant motors all runing high volume oil pumps and the newer units that i put a good radious on the teeth with the dremel. the teeth on these new cams r sharp. i have a crane roller in the new short block that needs the teeth smoothed, and yes all engines r running high volume pumps. all external pickups. there's a reason its the expendable part in the system but it doesn't have to be that expendable. just curious what others r running. thanks. if that 200.00 hughes gear would work, i would use it.....
