BSA Tachometer drive thrust washer
A thrust washer for the tachometer drive, listed under the crankcase in the parts book.
PN · 70-9383
This is a thrust washer out of the tachometer drive train, listed in the crankcase section of the parts book. It's a small item that sits in the drive works that runs the tach off the engine, taking up end float so the drive gear or shaft doesn't wander side to side under load.
