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 8).
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 distributor hold 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 gasket and apply a liberal amount
of the supplied lubricant to the distributor
gear. (The supplied O-rings can only be
used if the block has been modified as
shown in Figure 9.)
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. Page 8 shows how to set the rev limiter and
connect the tachometer.
