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. MALLORY IGNITION 550 MALLORY WAY , CARSON CITY , NV 897012 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.
