Next, crank the engine over several times. Before pulling the distributor out, make sure the rotor is
in the position that lines up with the original removal mark. Then pull the distributor out and inspect
the gear pattern shown on the grease. The proper mesh will leave an even pattern in the middle of
the gear. Adjust the slip collar to obtain the correct mesh.
INSTALLING THE DISTRIBUTOR
1. With the slip collar adjustment set, install the gasket and O-rings (if necessary).
Note: Do not use the O-rings unless the block has been modified as in Figure 1.
2. Apply a liberal amount of the supplied lubricant to the distributor gear.
3. Install the distributor making sure that the rotor comes to rest pointing at the fixed mark. If the
distributor will not fully seat with rotor pointing to the marked position, you may need to rotate the oil
pump shaft until the rotor lines up and the distributor fully seats.
4. Position and tighten the hold-down clamp onto the distributor.
5. Install the distributor cap. It is recommended to use a drop of Blue Loctite to the distributor
cap hold down bolts.
6. Install the spark plug wires one at a time to ensure correct location.
