CONNECTOR
After removing the coil, check the condition of the
arc seal (1981 shown, other years similar)
Ignition Coil
Perform steps 1, 2, 4, 5, and 6 of the previous
distributor cap replacment procedure. Install
the new coil, being sure to use the dielectric
compound supplied with most coils to lubri-
cate the rubber washer.
Ignition Rotor
Remove the distributor cap as previously
outlined. Loosen the rotor retaining screws
(most screws will stay attached to the rotor)
and lift the rotor off of the mainshaft assem-
bly. During installation, note the locations of
the different locating "dowels" (2) on the un-
derside of the rotor. These dowels help to
prevent incorrect rotor installation by allow-
ing the rotor to be installed in only one way.
Vacuum Advance Unit (if so equipped)
1. Remoy/e the distributor cap and rotor as
previously outlined.
2. Disconnect the hose from the vacuum
advance unit.
3. Remove the two vacuum advance unit
retaining screws and pull the unit outward.
4. Rotate the unit to disengage the oper
ating rod from the distributor.
5. Reverse the previous steps to install.
Module
1. Remove the distributor cap and rotor as
previously outlined.
2. Carefully disconnect the wiring from the
module.
3. Remove the two module retaining
screws and lift the module out of the distrib
utor housing.
4. Apply a light coating of silicone dielec
tric compound to the distributor housing in
the module mounting area before installing
the new module. The silicone compound is
used to transfer heat from the module to the
