Distributor

REMOVAL



  1. Unfasten the retaining clips or remove the retaining screws and lift the distributor cap straight off. It will be easier to install the distributor if the wiring is left connected to the cap. If the wires must be removed from the cap, mark their positions to aid in installation.
  2.  

While it is possible to remove and install the distributor without setting up No. 1 to TDC by marking the rotor's position in relation to the distributor body, it is good practice to always set the engine with cylinder No. 1 at TDC of the compression stroke. This is the best point of reference.

  1. Remove the dust cover and mark the position of the rotor relative to the distributor body; then mark the position of the body relative to the cylinder head.

  1. 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, such as for engine rebuilding), after the distributor has been removed. The relationship between the position of the distributor and the position of the engine is critical if the spark is to be sent to the proper place at the proper time.

  3. Remove the distributor O-ring, discard and install a new one. Apply a light coat of engine oil on the O-ring.

INSTALLATION



Timing Not Disturbed
  1. If the crankshaft timing mark and notch on the distributor body were not aligned at removal but alignment marks were made on the rotor, distributor body and cylinder head before removal, align these matchmarks on the distributor with the rotor. Position the distributor to align with the mark made on the block. Insert the distributor in the block, taking care NOT to damage the drive gear at the bottom or to knock all the marks out of alignment.
  2.  
  3. Tighten the pinch-bolt to 14 ft. lbs. (19 Nm).
  4.  
  5. Install the distributor cap and wires. Check the ignition timing.
  6.  
  7. Check the idle speed.

Timing Disturbed

If the engine has been cranked, dismantled, or the timing otherwise lost, proceed as follows:

  1. Determine Top Dead Center (TDC) of the No. 1 cylinder's compression stroke by removing the spark plug from the No. 1 cylinder and placing your finger over the spark plug hole. Turn the engine (with a wrench on the crank pulley bolt) until the timing marks align at 0 degrees. A definite compression can be felt pressing against your finger. Doing this is most important, because the timing marks also align during the exhaust stroke, but no compression will be felt. If the distributor is installed incorrectly (180 degrees out of time), the engine may be damaged, if it starts at all.
    1. To verify that the timing is correct, remove the cylinder head cover. With a wrench on the crankshaft balancer center bolt turn the crankshaft pulley clockwise until the notch on the pulley aligns with the 0 mark on the timing chain cover.
    2.  
    3. Look at the backs of the camshaft drive gears. Verify that the timing marks with one and two dots are in a straight line on the head surface. If not, turn the crankshaft exactly one full turn (360 degrees).
    4.  
    5. Locate the notch marks on the distributor end next to the drive gear. Align groove on the housing with the protrusion on the drive gear.

On engines which have the spark plugs buried into the cylinder head, use a compression gauge.

  1. Install the rotor. Position the rotor so it is at the No. 1 cylinder firing position.
  2.  
  3. Install a replacement O-ring on the distributor body and lightly oil. Slowly insert the distributor into the cylinder block aligning the center of the flange with the bolt hole in the cylinder head.
  4.  
  5. Tighten the pinch-bolt to 14 ft. lbs. (19 Nm).
  6.  
  7. Install the distributor cap and wires. Check the ignition timing.
  8.  
  9. Check the idle speed.
