HOW TO INSTALL THE DISTRIBUTOR
1. If the distributor to be replaced has not already been
removed from the engine, remove its cap. Do not
remove the spark plug wires at this time.
2. Crank the engine slowly until the rotor blade aims at a
fixed point on the engine or firewall. Note this point for
future reference.
3. Unplug all external connectors coming from the
distributor.
4. Now put the existing cap back on and note and mark
which spark plug wire the rotor (blade) is pointing at.
Then number the wires according to cylinder and
remove the wires. If in doubt you can leave the wires
connected to the old cap and transfer them to the new
cap and distributor later in the process (see point # 9).
5. Loosen and remove the distributor hold-down bolt and
clamp. Lift the old distributor out. At this point the rotor
may spin and move from its position. This
is because of the distributor gear.
6. Lower the new distributor into position. The rotor
should be aimed at the same fixed point as was the
rotor from the old distributor. After the new distributor
has been lowered into place, you may find that it
hasn't seated firmly against the intake manifold. This
indicates that the lower end of the distributor shaft is
not properly aligned with the oil pump drive rod. Do not
attempt to force the distributor into position.
7. Reinstall the hold-down clamp and thread the bolt just
enough to exert a very slight pressure against the
distributor. If the distributor was not firmly seated,
manually rotate the engine until the distributor drops
down into place.
8. With the distributor properly seated, tighten the
hold-down bolt just enough so that the distributor is
held in place, but can still be rotated with a little effort.
9. Remove the plug wires one at a time from the old cap
and install them in the corresponding positions of the
new cap. After all wires have been transferred, verify
that the wire in the terminal post that is aligned with the
rotor leads to number one cylinder. If you are unsure of
cylinder number position or firing order, this information
can be found in the service manual that covers your
particular engine. Put on the distributor cap.
10. Reconnect the wiring lead from the distributor to the
ignition switch. At this time you can begin timing.
