Note: When installing the distributor for the ﬁrst time, it is recommended to place the switches in

the locked-out timing position. This will assist you in setting the timing curve by ensuring

that the total timing is correct.

1. Remove the existing distributor cap without disconnecting any of the spark plug wires.

2. With the cap off, crank the engine until the

rotor is aimed at a ﬁxed point on the engine

or ﬁrewall. Note this position by making a

mark (Figure 5).

3. Place the distributor cap back on and

note which plug wire the rotor is pointing

to. MARK THE SPARK PLUG WIRES and

remove the distributor cap.

4. Disconnect the wiring from the distributor.

5. Loosen the distrib utor hol d down clamp

and slide the clamp out of the way.

6. Lift the distributor out of the engine. Note

that the rotor rotates as you lift the distributor

out. This is due to the helical cut gear and

should be taken into consideration when

installing the new distributor.

7. Install the O-ring and apply a liberal amount

of the supplied lubricant to the distributor

gear.

8. Install the distributor making sure that the rotor comes to rest pointing at the ﬁxed mark. If the

distributor will not fully seat with the 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.

9. Position and tighten the hold down clamp onto the distributor.

10. Install the distributor cap and spark plug wires one at a time to ensure correct location. A wire

retainer is supplied to secure the wires in place. Align the mounting bosses and use the supplied

1.5" self-tapping Phillips screws to hold the retainer in place.

11. Proceed to wiring the distributor as shown in Figures 6 and 7. Review the starting and tuning tips

information and install the Timing Tape as shown on page 7 before starting the engine.
