To install:

Replace the O-rings on the coupling shaft or ignition system performance may suffer. Lubricate the O-rings and the end of the camshaft.


WARNING
Don't try to fully seat the distributor using the distributor retainers. If the distributor will not seat by hand, it's not properly aligned with the camshaft. Rotate the crankshaft until the engine is at the number 1 cylinder TDC (camshaft sprocket pin at the 9 o'clock position). Rotate the distributor coupling until the camshaft sprocket pin slot aligns with the distributor base timing mark. Install the distributor using hand pressure to fully seat the distributor.

  1. Install the distributor assembly into position with the driveshaft in the end of the camshaft. Rotate the distributor coupling until the camshaft sprocket pin slot aligns with the camshaft sprocket pin. Slide the distributor onto the end of the camshaft until fully seated on the engine front cover.
