An exploded view of the starter is shown above. The starter uses a
gear type engagement, similar to an automobile. Energizing the starter
motor causes the helix on the starter to drive a pinion gear into eng
agement with a ring gear. The pinion gear then cranks the engine.

When the starter motor is energized, the pinion gear should move out
on its helix to engage the ring gear. If the motor drive does not re
act properly, inspect helix-and pinion gear for freedom of movement.
If sticking or binding occur, the condition must be corrected. Pinion
must move freely on its helix. DO NOT LUBRICATE DRIVE ASSEMBLY.
