On all four-cylinder engines, except the 20R and 22R, and the distributor is on the right (passenger's) side. On 20R and 22R engines and all sixes, 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:
- Unfasten the retaining clips and lift the distributor cap straight up. 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.
- 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.
- Disconnect the coil primary wire and the vacuum line(s). If the distributor vacuum unit has two vacuum lines, mark which is which for installation.
- Remove the pinch bolt and lift the distributor straight up, 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.
Timing Not Disturbed
- Insert the distributor in the block and align the matchmarks made during removal.
- Engage the distributor driven gear with the distributor drive.
- Install the distributor clamp and secure it with the pinch bolt.
- Install the cap, primary wire, and vacuum line(s).
- 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.
- Start the engine. Check the timing and adjust it and the octane selector, as outlined in .
If the engine has been cranked, dismantled, or the timing otherwise lost, proceed as follows:
- 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 thumb over the spark plug hole. This is important because the timing marks will also line up with the last cylinder in the firing order in its exhaust stroke. Crank the engine until compression pressure starts to build up. Continue cranking the engine until the timing marks indicate TDC (or 0).
- Next, align the timing marks to the specifications given in the Ignition Timing column of the Tune-Up Specifications chart at the beginning of .
- 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.
- 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.
- Align the matchmarks on the distributor body and the blocks 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.
Oil the distributor spiral gear and the oil pump driveshaft end before distributor installation.
- Rotate the distributor, once it is installed, so that the points are just about to open or the projection on the pickup coil is almost opposite the signal rotor tooth. Temporarily tighten the pinch bolt.
- Remove the rotor and install the dust cover. Replace the rotor and the distributor cap.
- Install the primary wire and the vacuum line(s).
- 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.
- Start the engine. Adjust the ignition timing and the octane selector, as outlined in .
