The document provides instructions for installing a distributor on an engine where the engine was not disturbed or was disturbed. For an undisturbed engine, it instructs to lubricate the O-ring, install the distributor ensuring the gears engage and marks align, and then connect other parts and check ignition timing. For a disturbed engine, it provides steps to locate top-dead-center, position the distributor rotor, then follow the same installation steps as an undisturbed engine.

1. INSTALLATION
Engine Not Disturbed
1. Using engine oil, lubricate the O-ring.
2. Install or connect the following:
o Distributor
NOTE: Be sure to engage the distributor drive gear or tangs with the camshaft gear or
slot. Align the mark that was made on the distributor housing with the mark that was
made on the cylinder head.
o Distributor hold-down bolt(s)
o Electrical connector(s)
o Distributor cap
o Negative battery cable
3. Start the engine and check or adjust the ignition timing.
Engine Disturbed
1. Remove or disconnect the following:
o Spark plug wire from the No. 1 cylinder spark plug
o Spark plug from the No. 1 cylinder
2. Press a thumb over the spark plug hole.
3. Using a wrench on the crankshaft pulley, rotate the crankshaft until pressure is felt at
the spark plug hole, indicating the piston is approaching TDC on the compression stroke.
Continue rotating the crankshaft until the crankshaft pulley mark aligns with the timing
cover indicator.
4. Place the distributor rotor in position so that it aligns with the No. 1 spark plug wire
tower on the distributor cap.
5. Using engine oil, lubricate the O-ring.
6. Install or connect the following:
o Distributor
NOTE: Be sure to engage the distributor drive gear or tangs with the camshaft gear or
slot. Align the mark that was made on the distributor housing with the mark that was
made on the cylinder head.
o Distributor hold-down bolt(s)
o Electrical connector(s)
o Distributor cap
o Spark plug in the No. 1 cylinder and connect the spark plug wire
o Negative battery cable
7. Start the engine and check or adjust the ignition timing.
