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. Install the gasket using plenty of the supplied lubricant.
8. 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.
9. 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.
10. 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.
11. Reconnect the wiring lead from the distributor to the
ignition switch. At this time you can begin timing.
