INSTALLING THE DISTRIBUTOR
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. Note
this position by making a mark (Figure 9).
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. D i s c o n n e c t t h e w i r i n g f r o m t h e
distributor.
5. Loosen the distributor hold-down
clamp, slide the clamp out of the way
and lift the distributor out of the engine.
6. Install the supplied O-ring seal in the
groove on the distributor land. Apply a
thin layer of oil to the housing O-ring.
7. 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.
8. Position and tighten the hold-down
clamp onto the distributor.
9. Install the rotor and distributor cap. It is
recommended to use a drop of Blue
Loctite on the distributor cap hold down
bolts.
10. Install the spark plug wires from the old cap
one at a time to ensure correct location.
