REMOVAL and INSTALLATION
See Figures 1 and 2
- Disconnect the negative battery cable.
- Disconnect the wiring harness at the distributor and the vacuum line at the distributor vacuum advance unit.
- Remove the distributor cap.
Mark the distributor body in reference to where the rotor is pointing. Mark the distributor hold-down bracket and cylinder head for a reinstallation location point.
- Remove the hold-down bolt and the distributor from the cylinder head. Do not rotate the engine after the distributor has been removed.
If the engine was not rotated proceed as follows:
- Align the reference marks on the distributor housing to the distributor hold-down bracket.
- Install the distributor into the offset slot in the camshaft, then the hold-down bolt.
- Connect vacuum hoses and electrical connectors to the distributor.
- Install the distributor cap, then connect the battery negative cable. Check and/or adjust the ignition timing.
If the engine was rotated while the distributor was removed, place the engine on TDC of the compression stroke to obtain the proper ignition timing.
- Remove the No. 1 spark plug.
- Place thumb over the spark plug hole. Crank the engine slowly until compression is felt. It will be easier to have someone rotate the engine by hand, using a wrench on the crankshaft pulley.
- Align the timing mark on the crankshaft pulley with the 0 degrees mark on the timing scale attached to the front of the engine. This places the engine at TDC of the compression stroke.
- Turn the distributor shaft until the rotor points to the No. 1 spark plug tower on the cap.
- Install the distributor into the engine. Be sure to align the distributor-to-engine block mark made earlier.
- Install the No. 1 spark plug. Connect all vacuum hoses and electrical connectors to the distributor.
- Install distributor cap, then connect the battery negative cable.
- Check and/or adjust ignition timing.
