Starter Shafts and Actuating Mechanism for Sportster →1980 and Big Twin →1988

Between starter motor and clutch

A whole series of parts ensure that the rotating power of the starter motor reaches the clutch. Within the starter housing sits the starter shaft and on it the pinion with a sleeve, plus a gear that provides the reduction of the speed. The bushing runs in bearings and, of course, it takes a whole lot of small parts to keep it all together and working nicely and smoothly.
