While the crankshaft is turned clockwise (as seen from the front of the engine), push on the timing pin (A) until it slides into the groove (slot) in the fuel injection pump camshaft. 3. Remove screw (1) and washer (2) from the end of the engine camshaft. 4. Remove automatic timing advance (3).Install Automatic Timing Advance
1. If the timing mark on the crankshaft and the timing mark on the camshaft gear are not in alignment, turn the crankshaft clockwise (as seen from the front of the engine)until the marks are in alignment.2.

CAMSHAFT REMOVED FOR PHOTO ILLUSTRATION4. Install screw (4) and tighten it to a torque of 70 5 lb. in. (6.9 0.6 N m). Put marks (stake) on the screw in two places with a hammer and punch.
Put marks (stake) on screw (4) carefully. Too much force pushes the shaft extension into the camshaft and takes away all end clearance.
5. After marks are put on (stake) on the screw (4), the end clearance for the gear and weight assembly must be .003 to .037 in. (0.08 to 0.94 mm). This end clearance will prevent binding against the washer, camshaft end, or camshaft gear.end by:a) install timing gear cover and oil pump
