contact pattern

When I set up gears and I really don't have a starting point such as you are doing ( since you really don't know how thick the shims are that were behind the large race). I make large shim amounts like .010-.015, either adding or taking away until I can tell I'm heading in the right direction. You know the thickness of the shim behind the bearing, it stands to reason that if you pulled out pieces of a shim or shims that were sticking out from under the race that the pinion was closer to the ring gear than just the shim behind the bearing would put it. Am I making sense to you? Yukon gear makes some good installation manuals. Here is a link.
