Brushes & Springs
- Measure brush length and replace if less than specification. See MINIMUM BRUSH LENGTH SPECIFICATIONS . Check brush springs for corrosion or damage. Ensure spring tension is sufficient to press brushes against commutator.
- Check condition of brush holders, spring clips and insulation between positive and negative holders. Repair or replace as required. Ensure Brushes move freely in holders. Before installing new brushes, buff commutator end of brush with emery cloth.
