Are there different thicknesses of snap rings that retain the bearing on the input shaft? I just measured the bearing surface on an 18 spline input shaft and it was about .800" from the front gear surface to the snap ring groove. This would place the inner bearing race .026" into the snap ring groove.

Snap ring groove is approximately .118" wide. Which would make the .097" snap ring the closest match for my application. Ideally I would need one that is .104" thick to match the bearings I got from Brewers.

The snap ring installed with the original bearing was .091" thick.
