FIRING ORDER
To avoid confusion, replace spark plug wires
one at a time.
1974-84 HEI
housing does not sit properly on the block,
the oil pump shaft is not engaging with the
distributor shaft. In this case, you can do one
of two things:
a. Remove the distributor and turn the
oil pump driveshaft with a long screw
driver to align the pump driveshaft slot with
the "blade" of the distributor shaft. This is
done strictly by visual approximation.
b. Apply downward pressure on the dis
tributor housing (NOT the rotor) and have
someone "tap" the ignition key to slowly
turn the engine over until the distributor
falls into its proper position. After doing
this, it is recommended that you recheck
the timing by repeating steps 1 and 2.
5. On conventional ignitions, after proper
positioning is assured, turn the distributor
housing so that the points are just opening.
6. Install the distributor hold-down bolt
and plate. Snug down the retaining bolt.
7. Connect the vacuum advance hose, tach
drive cable, and injection drive cable, on ve
hicles equipped with these items.
8. Connect all wiring and adjust the igni
tion timing as previously outlined.
9. Install the ignition shielding.
H.E.S. COMPONENT REPLACEMENT
Distributor Cap
1. Disconnect the feed, module, and ta
chometer wiring from the drivers side of the
distributor cap. Do so by releasing the wiring
connector retaining tabs and carefully pulling
downward on the connectors.
2. Locate the locking tabs of the spark plug
wire retaining ring (on the distributor cap).
Move each of the two locking tabs outward to
release the retaining ring. With the plug wires
still attached to the ring, pull the ring and
wires off of the distributor cap and move the
assembly out of the way.
3. Release the distributor cap hold-down
screws (push downward and counterclock
wise) and lift the cap assembly off of the dis
tributor.
4. Remove the coil cover from the distrib
utor cap (4 fasteners).
5. Push the spade terminals upward and
out of the distributor cap.
6. Remove the four coil screws and lift the
coil, spring, carbon contact, and rubber
washer out of the distributor cap.
7. Reverse the previous steps to assemble,
using a new cap. Lubricate the rubber washer
with dielectric lubricant during assembly.
