Starter Brush: Testing and Inspection
Brush and Brush Holder
1. Check the brushes for free movement in brush holders. Inspect the brushes for excessive wear. Where the brush leads are insulated, make sure the
insulation is not burned or worn.
2. The brushes should be well seated to the commutator, that is, contacting the commutator over at least 60 percent of the brush contact area. If not,
fit the brushes to the commutator with fine sandpaper until the desired seating area is obtained. Do only one brush at a time. Clean the brushes and
commutator with compressed air. Make sure no abrasive particles from the sandpaper are embedded in the contact area of the brushes.
3. Mark each brush and the brush holder with which it was seated to ensure assembly in the same position.
