Brass shavings from distributor gear and new billet cam

<< < (2/3) > >>

masracingtd1167:
Take a look at the cam gear and make sure there are no sharp edges . It looks like something was cutting into the gear also make sure the distributor is not bottoming out on the oil pump shaft . When you run a steel billet cam you have t use a bronze gear .

FEDNV:
I have checked the cam gear even before I installed it and it had no sharp edges either before or after taking it out.  It is the same magneto, we just changed cams and distributor gear.  Could it being a used gear have an alignment issue as it may have been warn by the previous cam?

AWAG:
I am far from an expert but it looks to me like all the wear is below center on the distributor gear. Like the distributor is to high. If you only ran one gasket make sure the distributor isn't bottoming out on your oilpump shaft.

BK:
I think Spud had a post on hear or his website re; distributor gear wear and which gear to use and not use. If your driving the oil pump with the distributer pressure will have an affect on how the gear wears.
