Re: oil pump cam gear
Mine is a 8CM but the engine is tore down for rebuild. Cam's oil pump gear is loose and sloppy on the stub. Builder said don't risk fixing it, so I got a new cam.
If yours is tight you should be ok. I'd like to Zap my new cam gear with a spot weld of some 7018. But I'm not going to. Gene |

Re: oil pump cam gear
I would NOT weld it....The cam is cast iron and the gear is steel..The gear is carburized and welding heat will draw the temper.
I pin the gear on race engines by drilling on the parting line and tapping for a 8-32 set screw..Loctite the screw and peen over the edge of the hole after it is in. |
