The red shim serves as nothing more than a spacer between the outer race of the lower bearing in the brass gear and the outer race of the bearing that is mounted inside the housing. Critical to have as it stops the two bearings from binding but has nothing to do with load or pre load. The only bearing that provides load adjustment in the entire system is the outer conical bearing ad it’s tightness. Over tightening will cause drag and wear the bearing quicker. Too loose and you’ll get end float of the shaft and it won’t run true in the housing.

How this clears things up
