STARTER MOTOR REPAIR (CONT).
CLEANING/INSPECTION/REPAIR:
Dry cleaning solvent is potentially dangerous. Avoid repeated and prolonged
breathing of vapors and skin contact with the liquid. Do not use near open flame,
arcing equipment, or other ignition source. Always wear eye protection and
protective clothing.
Death or serious injury could occur if compressed air is directed against the skin.
Do not use compressed air for cleaning or drying unless the pressure is/has been
reduced to 30 psi (2.11 kgcm2) or less. When working with compressed air always
use chip guards, eye protection, and other personal protective equipment.
1.
Clean starter components with dry cleaning solvent. Dry with compressed air.
2.
Inspect field frame, lever housing and nose housing for cracks.
3.
Inspect brushes for wear and cracks.
4.
Inspect drive for worn broken or missing teeth.
5.
Inspect commutator on armature for evidence of wear, arcing, or burning.
6.
Repair is limited to the replacement of damaged components.
TEST:
1.
Using ohmmeter, check that field coils are not grounded to field frame. Check field coils at three positions.
2.
Check for continuity between solenoid terminals "S", "M", and 'G". Replace solenoid ifcircuit is open.
3.
Check armature for short circuits, opens, and grounds. Minor shorts can be repaired by cleaning out area between
armature plates. If armature indicates an open or ground, replace.
