The set up games begin: I was not as lucky as I had hoped. After snugging caps down with original shims I had no back lash you could not turn ring or pinion at all.
This means I need to use the aftermarket shims that came with my rebuild kit. To increase back lash You need to move the ring gear away from the pinion by taking out shims from the left side and adding the exact amount to the right. A micrometer comes in handy here. Of course if you have too much backlash you would do the opposite.
Almost all ring and pinions call for .006-.010. The Motive gears I'm using call for .007-.009
