Print

Service consists of inspection or replacement of the distributor cap, rotor and spark plug wires. Removal and installation of the distributor assembly is covered in Engine & Engine Overhaul of this repair guide. Ignition coil testing, removal and installation is also covered in Chapter 3 of this manual.

  1. Disconnect the negative battery cable.
  2.  
  3. The distributor cap is held on by two screws. Release them with a screwdriver and lift the cap straight up and off, with the wires attached. Inspect the cap for cracks, carbon tracks, or a worn center contact.
  4.  
  5. Pull the ignition rotor straight up to remove. Replace it if its contacts are worn, burned, or pitted. Do not file the contacts.
  6.  

To install:
  1. If removed, press the rotor firmly onto the shaft. It only goes on one way, so be sure it is fully seated.
  2.  
  3. Inspect the plug wires for cracks or brittleness. Replace them one at a time to prevent crosswiring, carefully pressing the replacement wires into place. The cores of electronic wires are more susceptible to breakage than those of standard wires, so treat them gently.
  4.  

Check the spark plug cable routing and always make sure the plug wires are in the correct plug wire bracket.

  1. Install the distributor cap and tighten the two screws.
  2.  
  3. Disconnect the negative battery cable.
