  1. Detach the vacuum hoses at the distributor.
  2.  
  3. Disconnect the coil wire and remove the distributor cap.
  4.  
  5. Disconnect the condenser wire.
  6.  
  7. Bring No. 1 cylinder to top dead center (TDC) on the compression stroke by rotating the engine so that the rotor points to the No. 1 spark plug wire tower on the distributor cap and the timing marks are aligned at 0. Mark the rotor-to-distributor relationship. Also matchmark the distributor housing-to-crankcase relationship.
  8.  
  9. Unscrew the distributor retaining screw on the crankcase and lift the distributor out.
  10.  

To install:
  1. If the engine has been rotated since the distributor was removed, bring the No. 1 cylinder to TDC on the compression stroke and align the timing marks on 0. Align the match-marks and insert the distributor into the crankcase. If the matchmarks are gone, have the rotor pointing to the No. 1 spark plug wire tower upon insertion.
  2.  
  3. Replace the distributor retaining screw and reconnect the condenser and coil wires. Reinstall the distributor cap.
  4.  
  5. Retime the engine.
  6.  

Distributor Driveshaft
  1. On carbureted engines, remove the fuel pump.
  2.  
  3. Bring the engine to TDC on the compression stroke of No. 1 cylinder. Align the timing marks at 0.
  4.  
  5. Remove the distributor.
  6.  
  7. Remove the spacer spring from the driveshaft.
  8.  
  9. Grasp the shaft and turn it slowly to the left while withdrawing it from its bore.
  10.  
  11. Remove the washer found under the shaft.
  12.  


CAUTION
Make sure that this washer does not fall down into the engine.

To install:
  1. Make sure that the engine is at TDC on the compression stroke for No. 1 cylinder with the timing marks aligned at 0.
  2.  
  3. Replace the washer and insert the shaft into its bore.
  4.  

Due to the slant of the teeth on the drive gears, the shaft must be rotated slightly to the left when it is inserted into the crankcase.

  1. When the shaft is properly inserted, the offset slot in the drive shaft of Type 1 and 2/1600 engines will be perpendicular to the crankcase joint and the slot offset will be facing the crankshaft pulley. On Type 3, the slot will form a 60 angle with the crankcase joint and the slot offset will be facing the oil cooler. On Type 4 engines, and Type 2/1700, 2/1800 and 2/2000 engines, the slot should be about 12 out of parallel with the center line of the engine and the slot offset should be facing outside the engine.
  2.  
  3. Reinstall the spacer spring.
  4.  
  5. Reinstall the distributor and fuel pump, if removed.
  6.  
  7. Retime the engine.
