This is the part we are discussing here:

The shaft end play is determined by the distance of the 27mm "bulge" and the 17mm shoulder. The shaft is trapped between the two bearings to control the end play (the in and out movement). It so happens that Yamaha sells hardened 20mm shims just for this very purpose, Yamaha part #90201-20276.

Enjoy.

Would this shim control lateral movement of the rear wheel?
