Removal begins with disconnecting the cable from the negative terminal of the battery. Next, remove the distributor cap cover (if equipped) and note the position of the raised "1" on the distributor cap. This marks the location for the number one cylinder spark plug wire terminal. Disconnect the main electrical connector and ground connector from the distributor. Remove the distributor cap. Using a socket and breaker bar on the crankshaft pulley bolt, rotate the engine until the rotor is pointing toward the number one spark plug terminal. Make a mark on the edge of the distributor base directly below the rotor tip and inline with it. Also, mark the distributor base and cylinder head to ensure that the distributor can be reinstalled correctly. Remove the distributor hold-down bolt, then pull the distributor straight out to remove it. For installation, insert the distributor into the engine in exactly the same relationship to the block that it was in when removed. To mesh the helical gears on the camshaft and the distributor, it may be necessary to turn the rotor slightly. Make sure the distributor is seated completely and the alignment marks made previously are aligned. If not, remove the distributor and reposition it. If the crankshaft has been moved while the distributor is out, locate Top Dead Center (TDC) for the number one piston and position the distributor and rotor accordingly. Loosely install the hold-down bolt. Install the distributor cap and tighten the screws securely. Plug in the electrical connectors. Reattach the spark plug wires to the plugs (if removed). Connect the cable to the negative terminal of the battery. Check and, if necessary, adjust the ignition timing and tighten the distributor hold-down bolt securely. Reinstall the distributor cap cover (if equipped).
