  1. Disconnect the negative battery cable.

  3. Label and disconnect the spark plug wires from the distributor cap.

Depending on the reason for removing the distributor cap, it may make more sense to leave the spark plug wires attached. This is handy if you are testing spark plug wires, or if removal is necessary to access other components and wire play allows you to reposition the cap out of the way.

  1. Matchmark the distributor cap with the distributor housing for installation reference.
  2.  
  3. Remove the two attaching screws securing the cap to the distributor. Remove the cap from the distributor.
  4.  
  5. Remove the attaching screw from the rotor. Remove the rotor from the distributor shaft.
  6.  

To install:
  1. Align and install the rotor on the distributor shaft. Tighten the attaching screw securely.
  2.  
  3. Align and install the distributor cap on the distributor housing. Tighten the attaching screw securely.
  4.  
  5. Lubricate the spark plug wire terminal ends with dielectric grease and connect the wires to their proper terminals on the distributor.

  7. Connect the negative battery cable.

INSPECTION



Clean the distributor cap and rotor. Carefully check all surfaces for cracks, carbon tracks, burns or other physical damage. Make sure the carbon button is free of damage. Check the cap terminals for dirt or corrosion. Check the rotor blade and spring closely for damage. Replace components as necessary.
