Becoming an vintage story around here, but I have several bronze gears on my desk as paper weights and letter openers (sharp teeth...yanked them before FUBAR hit). Had a sold roller for a year, not hardened cam gears at the time (2003-4) so bronze gears was it application-wise. A very disposal item in such applications (save the cam). Finally went to a solid flat tappet...nice iron gear has lasted since 2004 (I still have the habit of pulling the damn thing and checking twice a year). And yes...high output
oil pump.
The polymers were just coming out...
Do NOT forget to drain every damn
oil line, including the
oil cooler (get it flushed, then do it again, and then do it again).
