Distributor

See Figures 1 through 12

REMOVAL



On the 8R-C and 18R-C, the distributor is on the right (passenger's) side. On all other engines, the distributor is located at the front of the engine on the left (driver's) side. To remove the distributor, proceed in the following order:

  1. Unfasten the retaining clips 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.  
  3. 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.
  4.  
  5. Disconnect the coil primary wire and the vacuum lines, mark which is which for installation.
  6.  
  7. 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.

INSTALLATION-TIMING NOT DISTURBED



  1. Insert the distributor in the block and align the 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 cap, primary wire, and vacuum line(s).
  8.  
  9. Install the spark plug leads. Consult the marks made during removal to be sure that the proper lead goes to each plug. Install the high tension wire if it was removed.
  10.  
  11. Start the engine. Check the timing and adjust it with the octane selector (if equipped), as outlined in Engine Performance and Tune-up .
  12.  

INSTALLATION-TIMING LOST



8R-C, 18R-C, 20R, 22R (1981-82), F and 2F Engines

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

  1. Determine the 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 on a vacuum gauge over the spark plug hole. This is important because the timing marks will also line up with the cylinder in the firing order in its exhaust stroke.
  2.  


CAUTION
On engines which have the spark plugs buried in the exhaust manifold, use a compression gauge or a screwdriver handle, not your finger, if the manifold is still hot.

Crank the engine until compression pressure starts to build up. Continue cranking the engine until the timing marks indicate TDC or 0 .

  1. Next, align the timing marks to the specifications given in the Ignition Timing column of the Tune-Up Specifications chart at the beginning of Engine Performance and Tune-up .
  2.  
  3. Temporarily install the rotor in the distributor without the dust cover. Turn the distributor shaft so that the rotor is pointing toward the No. 1 terminal in the distributor cap. The points should be just about to open.
  4.  
  5. Use a small screwdriver to align the slot on the distributor drive (oil pump driveshaft) with the key on the bottom of the distributor shaft.
  6.  
  7. Align the matchmarks on the distributor body and the block which were made during the removal. Install the distributor in the block by rotating it slightly (no more than one gear tooth in either direction) until the driven gear meshes with the drive.
  8.  

Oil the distributor spiral gear and the oil pump driveshaft end before distributor installation.

  1. Rotate the distributor, once it is installed, so that the point are just about to open or the projection on the pickup coil is almost opposite the signal rotor tooth. Temporarily tighten the pinchbolt.
  2.  
  3. Remove the rotor and install the dust cover. Replace the rotor and the distributor cap.
  4.  
  5. Install the primary wire and the vacuum line(s).
  6.  
  7. Install the No.1 spark plug. Connect the cables to the spark plugs in the proper order by using the marks made during removal. Install the high tension lead if it was removed.
  8.  
  9. Start the engine. Adjust the ignition timing and the octane selector (if equipped), as outlined in Engine Performance and Tune-up .
  10.  

22R (1983-88), 22R-E and 22R-TE Engine

See Figure 13

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 or a vacuum gauge over the spark plug hole. This is important because the timing marks will also line up with the cylinder in the firing order in its exhaust stroke.
  2.  


CAUTION
On engines which have the spark plugs buried in the exhaust manifold, use a compression gauge or a screwdriver handle, not your finger, if the manifold is still hot.

Crank the engine until compression pressure starts to build up. Continue cranking the engine until the timing marks indicate TDC or 0 .

  1. Follow Step 2 of the above procedure.
  2.  
  3. Check that the rocker arms on the No. 1 cylinder are loose. If not, turn the crankshaft one complete revolution (360°).
  4.  
  5. Temporarily install the rotor.
  6.

  1. Slowly insert the distributor into the cylinder block. The rotor should be pointing upward and the distributor mounting hole should be approximately at the center position of the bolt hole.
  2.  
  3. When the distributor is fully installed, the rotor should rotate to the position shown in the illustration.
  4.  
  5. Remove the rotor and the dust cap. Install the pinch-bolt and tighten it slightly.
  6.  
  7. Align on of the teeth on the signal rotor with the projection on the signal generator (pick-up coil).
  8.  
  9. Tighten the pinch-bolt to 14 ft. lbs. (19 Nm).
  10.  
  11. Install the dust cover and the rotor. Replace the distributor cap and wires and check the ignition timing.
  12.  

3VZ-E Engines

See Figures 14 and 15

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