Installation of the camshaft timing pin
(1) Timing pin
(2) Camshaft
Install timing pin (1) through the timing pin hole and into the hole in camshaft (2). If the timing pin does not go into the hole in the camshaft, the engine is not in time and the camshaft position must be adjusted. Refer to "Camshaft Timing Adjustment" for the procedure.Camshaft Timing Adjustment
Table 1
Required Tools Qty
6V-6080 Torque Multiplier Gp 1
5P-1748 Socket 1 Note: Before you perform any timing adjustments, check the timing in order to ensure that an adjustment is necessary. Refer to "Camshaft Timing Check" for the procedure.If the camshaft is not timed with the crankshaft, the camshaft drive gear must be removed and the camshaft must be rotated. Perform the following procedure.
Put the No. 1 cylinder in the Top Center Position of the compression stroke and install the crankshaft timing pin. Refer to Testing and Adjusting, " Finding the Top Center Position for the No. 1 Cylinder" and Testing and Adjusting, "Crankshaft Position for Valve Lash Setting ". Remove all of the valve covers from the side of the engine that requires adjustment.

(1) Bolts
(2) Rocker arm shaft
Loosen bolts (1) that hold rocker arm shafts (2) until all of the rocker arms are free from the valve bridges. Note: For Vee engines, the gas tubes must be removed from the rear of the engine in order to remove the camshaft drive gear covers. Before you work on the fuel system, make sure that the main gas supply is OFF. Purge any remaining gas from the fuel system.

(7) Washer
(8) Plate
Use the following procedure to loosen camshaft drive gears (4):
Use the 6V-6080 Torque Multiplier Gp and the 5P-1748 Socket to loosen bolt (6).
Remove bolt (6) and washer (7). Remove bolts (5) and plate (8).
Put washer (7) between the camshaft and plate (8). Install bolt (6) finger tight.
Install bolts (5) finger tight.
Sudden movement of camshaft drive gear can occur when the camshaft drive gear is pulled off the taper of the camshaft. To prevent possibly personal injury, be sure that the bolt is installed (finger tight) to restrict the movement of the camshaft drive gear when the camshaft drive gear is pulled off of the taper of the camshaft.
Tighten bolts (5) evenly in order to pull camshaft drive gear (4) off the taper of the camshaft.

Installation of the camshaft timing pin
(9) Camshaft timing pin
Install the crankshaft timing pin. Remove camshaft timing pin (9) from the storage location.
Put camshaft timing pin (9) in the timing pin hole, and turn the camshaft until the timing pin goes into the hole in the camshaft.
After the camshaft is timed with the crankshaft, use the following procedure to tighten camshaft drive gear (4):
Remove bolts (5) and (6), plate (8) and washer (7).
Install washer (7) and bolt (6). Tighten bolt (6) by hand.
Remove the crankshaft timing pin and the camshaft timing pin.
Operate the prelube pump and turn the flywheel in the opposite direction of normal rotation for a minimum of 20 degrees.
Operate the prelube pump and turn the flywheel in the direction of normal engine rotation until the crankshaft timing pin can be reinstalled in the crankshaft. This procedure holds the backlash in the timing gears in the direction of normal engine rotation.
If the crankshaft timing pin location is missed, do not turn the flywheel in the opposite direction in order to install the
