What you are looking for is the pattern to be centered between the root of the tooth and the edge of the tooth with a rounded edge on the pattern and not a pointed edge on the pattern.
The pattern does come to a point at the root side of the tooth. Not at all bullet shaped. I did increase the pinion shim to .022. It was .018, not .016. How do I get rid of the sharp point? Back lash is set at .008-.010. The ring gear is marked .008 from Motive.
