removing palnut and regular nut on lower end of
distributor shaft. (CAUTION—Do not lose Woodruff key in shaft). Then remove hold-down screw in
advance arm, lift distributor out.
Distributor Installation Note—When installing distributor, first turn crankshaft to #1 cylinder firing
position (#1 piston on compression, ignition timing
mark on flywheel in center of inspection hole in
right front face of housing), turn distributor shaft
until rotor is at #1 segment in distributor cap (see
diagram) with contacts Just opening, Install distributor on engine and tighten hold-down screw in
advance arm. With oil pan removed, install drive
gear on lower end of distributor shaft (CAUTION
make certain that Woodruff key in place), being
careful not to disturb relative position of distributor
shaft and crankshaft when meshing gears, install
regular nut and palnut on distributor shaft. Check
Ignition Timing.
