HOW TO INSTALL THE DISTRIBUTOR
1. Disconnect the trigger wire from the coil (-) terminal.
Locate the spark plug wire on the original distributor
cap that that is used to set engine timing. See a
service manual for this location. Mark the distributor
cap and distributor housing at this spark plug wire
position.
2. Turn the engine crankshaft in the direction of rotation
until the timingmark lines up with the top dead center
(TDC) mark on the timing tab. See a service manual
for these locations.
3. Remove the distributor cap from the distributor. Do
not remove the sparkplug wires or coil wire at this
time. Make sure the rotor blade points to the mark
made on the distributor housing (from Step 2). If it
does not, repeat Step 2 until the timing mark lines
up (again) with the TDC markon the timing tab.
NOTE: Once you are finished with Step 3, DO NOT turn the
crankshaft until the new distributor is installed.
4. Note the direction that the rotor is pointing. If you
are replacing a vacuumadvance distributor, note the
direction the vacuum chamber is pointing. Remove
the distributor hold down clamp and remove the
distributor fromthe engine.
5. 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 distribu-
tor 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.
6. 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.
7. 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.
8. 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.
9. Reconnect the wiring lead from the distributor to the
ignition switch. At this time you can begin timing.
