Contact breaker points - removal and refitting

1. When significant pitting or burning of the contact faces has occurred, the contact set should be renewed. It is not an expensive item and is worth renewing as a preventive measure at alternate service intervals, even if apparently still in good condition.

Removal

2. Undo the two distributor cap retaining screws, lift off the cap and withdraw the rotor arm from the distributor shaft (see illustration).

Removing the rotor arm

3. Move the contact breaker arm spring blade away from the plastic insulator and slip the low tension and condenser lead terminals off the insulator (see illustration).

Refitting

5. Locate the new contact set on the baseplate and refit the retaining screw.

6.Move the contact breaker spring blade away from the insulator, fit the low tension and condenser leads and allow the spring blade to slip back into place. Make sure that the leads and the blade locate squarely in the insulator.

7. Check and adjust the contact breaker points gap or dwell angle, then refit the rotor arm and distributor cap.
