REMOVAL



See Figures 1 through 6

  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.  

Set cylinder No. 1 to TDC of the compression stroke. For all engines except 2R-E, set the timing mark at 0. On 2R-E, set the timing mark at 5 degrees.

  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 block.

  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. Align the 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.
  8.  

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°, except on the 2R-E. On the 2R-E, align the mark at 5°. A definite compression can be felt pressing against your finger. Doing this important; the timing marks also align during the exhaust stroke, but no compression will be felt.
  2.  

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

  1. Install the rotor. Position the rotor so it is at the No. 1 cylinder firing position.
  2.  
  3. Slowly insert the distributor into the cylinder block.
  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.
  10.
