REMOVAL AND INSTALLATION
DISTRIBUTOR
Removal
1.
Remove distributor cap. Position it and igni-
tion wires to one side.
2. Disconnect and plug diaphragm assembly
hose(s).
3. Separate distributor connector from wiring
harness.
4. Rotate engine to align stator assembly pole
and any armature pole.
5.
Scribe a mark on distributor body and engine
block to indicate position of distributor in en-
gine, and position of rotor.
6.
Remove distributor holddown bolt and clamp.
7. Remove distributor from engine. Do not rotate
engine while distributor is removed.

.
Rotate engine until No. 1 piston is on com-
pression stroke.
Align timing marks for correct initial timing.
Install distributor with rotor pointing at
number one terminal position in cap, and
armature and stator assembly poles
aligned.
Make sure oil pump intermediate shaft
properly engages distributor shaft. It may
be necessary to crank engine after distrib-
utor gear is partially engaged in order to
engage oil pump intermediate shaft and
fully seat distributor in block.
If it was necessary to crank engine, again
rotate engine until No. 1 piston is on com-
pression stroke and align timing marks for
correct initial timing.
Rotate distributor in block to align arma-
ture and stator assembly poles and verify
rotor is pointing at No. 1 cap terminal.
Install distributor holddown bolt and
clamp; do not tighten.
2.
If engine was not rotated while distributor was
removed and original distributor is being
replaced:
a. Position distributor in engine with rotor and
distributor aligning with previously scribed
mark. Armature and stator assembly poles
should also align, if distributor is fully seat-
ed in block and properly installed. Crank
engine if necessary to fully seat distributor
in block.
b. Install distributor holddown bolt and
clamp; do not tighten.
3. If engine was not rotated while distributor was
removed and new distributor is being
installed:
a. Position distributor in engine with rotor
aligned with previously scribed mark. If
necessary, crank engine to fully seat
distributor.
b. Rotate engine until timing marks for cor-
rect initial timing align and rotor is pointing
at No. 1 one cap terminal.
c. Rotate distributor in block to align arma-
ture and stator assembly poles.
d. Install distributor holddown bolt and
clamp; do not tighten.1
4.
If in steps 1-3 above the armature and stator
assembly poles cannot be aligned by rotating
distributor in block, pull distributor out of block
enough to disengage distributor gear and ro-
tate distributor shaft to engage a different dis-
tributor gear tooth and re-install distributor.
Repeat steps l-3 as necessary.
5. Connect distributor to wiring harness.
6. Install distributor cap and -ignition wires.
Check that ignition wires are securely con-
nected to distributor cap and spark plugs.
7. Set initial timing to specification.
8.
Tighten distributor holddown bolt to
specification.
9. Recheck initial timing. Readjust if necessary.
IO. Connect diaphragm assembly hose.
