Just installed my new SB solid roller cam with a Milodon gear drive and after everything is buttoned up, I found it has 0.015 end play/float. The Mopar bible says 0.010 max. Anyone else had this amount? Am I stressing about nothing?
Cheers Macka
That's WAY too much. The way you correct that is by machining the back side of the hub in a lathe. That will take up what is essentially cam thrust.
FWIW, I been using that gear drive for decades and I keep the thrust down to .005 max and like it at about .003. It has that roller thrust bearing. It doesn't need all that play.
Also, look down the lifter bores and I'd bet when you correct the end play, the lobe will be more centered in the lifter bore.
I'd fix that.
