- Loosen the distributor cap hold-down screws or, if equipped with spring clips, gently pry them away from the cap. Lift the cap straight off the distributor to prevent damage to the rotor points and spring.
- Wipe the distributor cap with a clean, damp cloth and dry with compressed air or a lint-free cloth. Inspect the cap for cracks, broken carbon button, carbon tracks, dirt or corrosion on the terminals. Replace the cap if it is worn or damaged.
- Position the distributor cap on the distributor base, noting the square alignment locator. Tighten the hold-down screws or reposition the spring clips.
- Reconnect the spark plug wires, if removed. Be sure to route them in their original locations and to connect them to the proper terminals.
See Figures 4, 5, 6 and 7
- Remove the distributor cap, as previously described.
- Loosen the rotor hold-down screws, if equipped, and lift the rotor straight off the distributor base assembly. If there are no hold-down screws, the rotor is a friction fit, and must be carefully pulled straight off the distributor shaft. Be sure to use steady, even effort, to avoid injury or damage to the rotor.
- Wipe the rotor with a clean, damp cloth and dry with compressed air or a lint-free cloth. Inspect the rotor for cracks, carbon tracks, burns, damaged points or spring. Replace the rotor if it is worn or damaged.
- Position the distributor rotor with its round and square locator pins (if equipped) matched to the distributor shaft plate and tighten the hold-down screws. For rotors without locator pins and screws, align the rotor with the bevel on the distributor shaft and push it firmly onto the shaft, with steady, even pressure.
- Apply a coating of silicone dielectric compound to single point rotors. Be sure to only apply it to the metallic tip of the rotor which extends to the side. Do not apply any of this grease to the raised portion of the rotor contact which presses against the carbon button in the distributor cap. Also, do not apply grease to any portion of a multipoint rotor.
- Reinstall the distributor cap, as previously described.
