Note: If the timing pins can not be installed in the camshaft, it may be necessary to loosen the rocker arm adjustment screws and the fuel injector adjustment screws. This is done so that the camshaft can be turned.
Install camshaft timing pin (6) in the camshaft.
Install the timing pin in the crankshaft.

Put plate (5) in position on camshaft drive gear (1). Install bolts (2) .
Apply Tooling (B) to the threads of bolt (3) .
Attach a suitable lifting device to camshaft drive gear (1). The weight of camshaft drive gear (1) is approximately 35 kg (77 lb). Place camshaft drive gear (1) in position on the camshaft. Install washer (4) and bolt (3). Tighten bolt (3) by hand.
Remove the crankshaft timing pin from the timing location.
Turn the flywheel backward about 20 degrees.
If the crankshaft is turned more than 20 degrees, interference between the pistons and the valves may occur.
Turn the flywheel in the direction of the 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 the normal engine rotation.
If you miss the location of the crankshaft timing pin, do not continue to turn the flywheel in the same direction. If you miss the location of the crankshaft timing pin, repeat Step 7 and Step 8.
Remove the camshaft timing pin and the crankshaft timing pin.
Use Tooling (A) in order to tighten bolt (3) to a torque of 2000 275 N m (1480 200 lb ft).
Strike plate (5) with a punch and a hammer. The punch must be made of brass or bronze. This will seat the gear on the tapered drive shaft. Repeat Step 11. Repeat this procedure until the torque does not change.
Verify the correct camshaft timing. Refer to Testing And Adjusting, "Camshaft Timing".
Remove the crankshaft timing pin and the camshaft timing pin. Return the pins to the correct storage locations.
Install the rear camshaft inspection cover on the side of the engine.End By: Install the governor drive. Refer to Disassembly and Assembly, "Governor Drive - Install".
