Distributor: Service and Repair

Removal
1. Remove distributor cap and position aside, then disconnect and plug diaphragm assembly hoses.
2. Disconnect distributor electrical connector from engine wiring harness.
3. Rotate engine to align stator assembly pole and any armature pole.
4. Mark position of distributor in engine and position of rotor on distributor housing for installation reference.
5. Remove distributor hold-down bolt and clamp, then lift distributor out of engine. Do not crank engine after distributor has been removed.

Installation
1. If engine was not cranked after distributor was removed, proceed as follows:
a. Position distributor in engine, aligning housing to block marks and rotor to housing marks made during removal. Armature and stator assembly poles should also align if distributor is fully seated. Crank engine if necessary to fully seat distributor in block.
b. Install distributor hold-down bolt and clamp. Do not tighten at this time.
c. Install distributor cap and wires and Torque screws to 18-23 inch lbs., then connect distributor electrical connector to engine wiring harness.
d. Set ignition timing, then Torque distributor hold-down bolt to 17-25 ft. lbs.
e. Connect diaphragm assembly hoses.
2. If engine was cranked after distributor was removed, proceed as follows:
a. Remove No. 1 spark plug and crank engine until compression pressure is felt in No. 1 cylinder. Slowly rotate engine until correct initial timing mark on crankshaft damper aligns with timing pointer.
b. Position distributor in engine with rotor at number one firing position and armature and stator assembly poles aligned. Ensure oil pump intermediate shaft properly engages the distributor shaft. It may be necessary to crank engine after distributor drive gear is partially engaged in order to engage the oil pump intermediate shaft and fully seat distributor in block.
c. Install distributor hold-down bolt and clamp. Do not tighten at this time.
d. Install distributor cap and wires and Torque screws to 18-23 inch lbs., then connect distributor electrical connector to engine wiring harness.
e. Set ignition timing, then Torque distributor hold-down bolt to 17-25 ft. lbs.
f. Connect diaphragm assembly hoses.
