Cleaning and Inspection

IMPORTANT: Do not use grease dissolving solvents to clean electrical compo-
nents, planetary gears or drive clutch. Solvent will damage insulation and wash the
lubricant out of the clutch drive and gears. Use clean rags and compressed air to
clean components.
1. Test over-running clutch action of drive. Pinion should turn freely in over-running di-
rection and must not slip in cranking direction.
2. Inspect pinion teeth for wear.
3. Inspect spring for tension and drive collar for wear.
4. Check that bearings roll freely. If any roughness is felt, replace bearing.
5. Inspect planetary gear assembly. Gears must mesh easily and roll freely with no bind-
ing.
