Distributor

REMOVAL



See Figures 1 through 5

  1. Disconnect the negative battery cable.
  2.  
  3. Unfasten the retaining clips (only remove the coil wire if necessary) and lift the distributor cap straight off. It will be easier to install the distributor if the spark plug wiring is left connected to the cap. If the plug wires must be removed from the cap, mark their positions to aid in installation.
  4.  
  5. Remove the dust cover and mark the position of the rotor relative to the distributor body; then mark the position of the distributor body relative to the engine block.
  6.  
  7. Detach the harness assembly connector.
  8.  
  9. Remove the pinch-bolt and lift the distributor straight out, away from the engine. The rotor and body are marked so that they can be returned to the position from which they were removed. Do not turn or disturb the engine (unless absolutely necessary) after the distributor assembly has been removed.

INSTALLATIONTiming Not Disturbed



  1. Insert the distributor in the block and align ALL matchmarks made during removal.
  2.  
  3. Engage the distributor driven gear with the distributor drive.
  4.  
  5. Install the distributor clamp and secure it with the pinch-bolt.
  6.  
  7. Install the distributor cap and fasten the harness electrical connector.
  8.  
  9. If necessary, install the spark plug wires and coil wire.
  10.  
  11. Start the engine. Check the timing and adjust it if necessary.
  12.  

Timing Disturbed
  1. It is necessary to place the No. 1 cylinder in the firing position to correctly install the distributor. To locate this position, the ignition timing marks on the crankshaft front pulley can be used.
  2.  
  3. Remove the No. 1 cylinder spark plug. Turn the crankshaft until the piston in the No. 1 cylinder is moving up on the compression stroke. This can be determined by placing your thumb over the spark plug hole and feeling the air being forced out of the cylinder. Stop turning the crankshaft when the timing marks indicate TDC or 0 .
  4.  
  5. Oil the distributor housing lightly where the distributor bears on the cylinder block.
  6.  
  7. Install the distributor so that the rotor, which is mounted on the shaft, points toward the No. 1 spark plug terminal tower position when the cap is installed. Of course, you won't be able to see the direction in which the rotor is pointing if the cap is installed, so lay the cap on the top of the distributor and make a mark on the side of the distributor housing just below the No. 1 spark plug terminal. Make sure that the rotor points toward that mark when you install the distributor.
  8.  

On the VG30i and VG30E engines, align the mark on the distributor shaft with the protruding mark on the housing.

  1. When the distributor shaft has reached the bottom of the hole, gently move the rotor back and forth slightly until the driving lug on the end of the shaft enter the slots cut in the end of the oil pump shaft and the distributor assembly slides down into place.
  2.  

On the VG30i and VG30E engines, the distributor rotor tip should be in the 11 o'clock position.

  1. Fasten the distributor hold-down bolt.
  2.  
  3. Install the spark plug into the No. 1 spark plug hole.
  4.  
  5. Install the distributor cap and engage the harness electrical connector.
  6.  
  7. If necessary, attach the spark plug wires and coil wire.
  8.  
  9. Start the engine. Check the timing and adjust it if necessary.
  10.
