Description

Thrust Washer – Mainshaft – 0.130 Inch is a gearbox internal component positioned at the 3rd gear location on the mainshaft in the Series 1, Series 2, and Series 3 manual gearbox assembly.

The thrust washer controls axial end-float of the 3rd gear on the mainshaft, maintaining correct gear positioning and preventing excessive lateral movement during gear engagement. It is a precision-ground flat washer measuring 0.130 inches (130 thou) in thickness, and forms part of the selective-fit shim stack used to set mainshaft end-float to the correct tolerance during gearbox rebuild.
