REMOVAL AND INSTALLATION
REMOVAL
1. Disconnect the primary wire at
the
coil.
Disconnect the
vacuum
advance line at
the
distributor.
Remove the distributor cap.
2. Scribe a mark on the distribu-
tor body
and
engine block indicating
the position of the body in the block,
and scribe another mark on the dis-
tributor body indicating the position
of the rotor. These marks can be used
as guides when installing the dis-
tributor in
a
correctly timed engine.
3. Remove the distributor hold
down bolt and clamp. Lift the dis-
tributor out of the block.
Do not rotate the crankshaft
while the diStributor is removed,
or it will be necessary to time the
engine.
INSTALLATION
1. If the crankshaft was rotated
while the distributor was removed
from the engine, it will be necessary
to time the engine. Rotate the crank-
shaft until No. 1 piston is on TDC
after the compression stroke. Align
the TDC mark on the timing pointer
with the timing pin on the crankshaft
damper. Position the distributor in
the block with the rotor at the No. 1
firing position.
Make sure
the oil
pump inter-
mediate shaft
properly
engages
the distributor
shaft.
It may be
necessary to crank the engine
with the starter,
after
the
dis-
tributor drive
gear is partially
engaged, in
order to
engage the
oil pump intermediate shaft.
