Cleaning and Inspection
IMPORTANT: Do not use grease dissolving solvents to clean electrical components,
planetary gears, or drive. Solvent will damage insulation and wash the lubricant out
of the 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 direc-
tion and must not slip in cranking direction. Check pinion teeth. Check spring for tension
and drive collar for wear. Replace if necessary.
2. Check that brush holders are not damaged or bent and hold brushes against commuta-
tor. Check brushes for wear.
3. Inspect armature commutator. If badly grooved or out-of-round, turn down and undercut
commutator.
4. Inspect all roller bearing surfaces for wear. Check that bearings roll freely. If any rough-
ness is felt, replace bearing.
5. Inspect planetary gear assembly. Gears must mesh easily and roll freely with no binding.
