Brush Holder: Testing and Inspection
CLEANING
CAUTION: Do not wash the starter drive because the solvent will wash out the lubricant and cause the starter drive to slip.
Wipe field coils, armature, commutator and armature shaft with a clean cloth. Wash springs, shims, thrust washer, trip collar, locking collar and
brush end housing assembly in solvent, and dry the parts.
INSPECTION
1. Check brushes for free movement in brush holders. Inspect brushes for excessive wear. Where brush leads are insulated, make sure insulation is
not burned or worn.
2. The brushes should be well seated to commutator, that is, contacting commutator over at least 60 percent of brush contact area. If not, fit brushes
to commutator with fine sandpaper until desired seating area is obtained. Do only one brush at a time. Clean brushes and commutator with
compressed air. Make sure no abrasive particles from sandpaper are embedded in the contact area of brushes.
3. Mark each brush and brush holder with which it was seated to permit assembly in the same position.
