Description

Starter Drive for the starter motor on the VM turbo diesel engine.

The drive carries the pinion and overrunning (one-way) clutch on the starter armature shaft. When the starter is energised the pinion is thrown forward to mesh with the flywheel ring gear and crank the engine; once the engine fires the one-way clutch lets the pinion overrun so the starter is not driven back. It is renewed when the pinion teeth are worn or chipped, or when the clutch slips or fails to engage.
