1968 Mustang Distributor Disassembly and Reassembly

  1. Remove the rotor.
  2. Disconnect the primary and condenser wires from the breaker assembly. Remove the points and condenser from the distributor.
  3. Remove the “E” clip that holds the vacuum advance to the breaker sub-plate. Then remove the screws that hold the vacuum advance unit to the distributor.
  4. Pull the primary wire into the distributor. You may need to use a small screwdriver to help get the grommet loose.
  5. Remove the spring clip, the flat washer and the spring washer that holds the breaker plate to the sub plate. Then remove the sub plate retaining screws and remove both plates from the distributor.
  6. Mark one of the distributor weights and its brackets. Also mark one of the weights and its pivot pin. Then carefully remove the weight springs.
  7. Lift the lubricating wick form the cam assembly. Remove the cam assembly retainer and lift the cam assembly from the distributor shaft. Remove the thrust washer.
  8. Remove the weight retainers and lift the weights out of the distributor.
  9. If the gear and shaft are to be used again, mark them so they can be easily reassembled. Then drive out the gear retaining roll pin and remove the gear. NOTE THE GEAR AND SHAFT MUST BE REPLACED AS A UNIT!
  10. Remove the shaft collar roll pin. Invert the distributor and press the distributor shaft out of the collar and distributor housing.

After cleaning and checking each part reassemble in reverse order. Be sure the marked spring assembly is placed in the correct location
