Outer retaining plate for the cush drive assembly in the primary chaincase, part number 68-3283.
This is the outer retaining plate for the cush drive assembly in the primary chaincase, part number 68-3283. It sits behind the clutch, holding the rubber cush drive components in place on the shock absorber, and shows up in the clutch and primary chaincase figures in our records.

The cush drive itself takes up the shock of engagement and power pulses before that load gets to the gearbox, and this plate is what keeps that assembly located and squared up under the clutch. Catalog appearances for this number run from 1969 through 1972.
