Crankshaft Thrust Washer Shim, Commando
Crankshaft thrust washer shim, 0.006″ thick.
This shim fits into the crankcases prior to fitting the bearing. It is used to reduce crankshaft end float. Clearly it will slightly reduce the bearing engagement, and so should probably not be used on racing or high performance engines.
For Norton Commando.
Made in England.
