Step 7

Put the distributor gasket in place (if one is used).

Place the distributor in the engine with the rotor

pointing in the same general direction as the original

distributor. Put the distributor hold down clamp in

place and tighten slightly.

Step 8

Turn the engine crankshaft in the direction of rotation

two full turns until the timing mark lines up (again)

with the TDC mark on the timing tab. Remove the

distributor hold down clamp and remove the distri-

butor from the engine.

Step 9

Check the mating pattern on the distributor drive gear.

The mating pattern centerline must be within 1/16”

(0.0625”) of the gear tooth’s centerline (figure 3).

Step 10

If the mating pattern centerline is above the gear

tooth’s centerline or more than 1/16” below the gear

tooth’s centerline, loosen the flange screw, move the

flange, tighten the flange screw and repeat steps 6-9.

Step 11

Clean off the gear marking compound on the distri

butor drive gear. Tighten the set screws. Put a small

amount of RTV silicone on the bottom of the flange at

the split (figure 4) to prevent oil and vapors (blow-by)

from leaking. Proceed to the distributor instructions.

Step 4

Place the distributor in the engine with the rotor

pointing in the same general direction as the original

distributor. It is not necessary to have the distributor

gasket in place at this time.

NOTE: The distributor shaft tongue must be

fully engaged into the oil pump drive. It may be

necessary to turn the oil pump drive, or turn the

engine crankshaft in the direction of rotation two

full turns until the timing mark lines up (again)

with the TDC mark on the timing tab, to allow the

distributor shaft tongue to fully engage into the oil

pump drive.

Step 5

Lift the distributor 0.010-0.030”. Slide the flange down

to rest on the intake manifold. Tighten the flange

screw. Remove the distributor from the engine.

Step 6

Coat the teeth of the distributor drive gear with gear

marking compound (White Lead; High Spot Blue™;

Prussian Blue™). Camshaft/moly lube may be used

instead of gear marking compound.
