General description
1. Although it is possible to remove the traction relay without removing the starter from the car, we still recommend removing the starter (Chapter 9).
Brushes
Removal
2. Remove the rear cover of the starter by unscrewing the small mounting bolt (photo).
3. To remove the brush for inspection, push back the spring with a small screwdriver and unscrew the wire mounting screw. Then remove the brush from the guide (photo).

4. In most cases, the brushes have wear limit marks in the form of grooves engraved on them; if these marks are no longer visible, the brushes are considered worn. If there are no marks, measure the height of the brush protrusion from the brush holder. The manufacturer does not specify any values, but the height should be at least 1(1 mm (photo).
5. If the brushes are badly worn, they should be replaced as a matched set.
6. If the brushes are still serviceable, clean them with a cloth dampened with solvent. Make sure that the brushes are evenly spring loaded and press firmly against the commutator rings. If there is any doubt about the condition of the brushes and springs, compare them with new components.
Installation
7. Install in the reverse order of removal.
Traction relay
Removal
8. Unscrew the nut of the lower terminal at the end of the traction relay, and carefully bend the conductive plate from the contact post (photo).
9. Remove the two bolts securing the traction relay to the bracket on the drive side.
10. Release the plunger of the traction relay from the starter drive lever, then remove the traction relay, noting the spring (photo).
Installation
11. Install in the reverse order of removal. Clean the solenoid, plunger and starter/solenoid contact surfaces, and lubricate the plunger/starter drive lever with multi-purpose grease (Duckhams LB10).
