Note: If the timing pins cannot be installed in the camshaft, it may be necessary to loosen the rocker arm and the adjusting screws of the gas admission valve. 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 (4) .
Use a suitable lifting device. The weight of the camshaft drive gear is approximately 35 kg (77 lb). Position the camshaft drive gear (1) . Install washer (3) and bolt (4) . Tighten bolt (4) by hand.
Remove the crankshaft timing pin from the timing location.
Turn the flywheel backward about 20 degrees.Note: 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.Note: If you miss the location of the crankshaft timing pin, do not turn the flywheel. If you miss the location of the crankshaft timing pin, repeat Step 7 and Step 8.
In order to prevent the crankshaft from turning, engage the manual barring group. Tighten the locking guide to a torque of 270 25 N m (200 18 lb ft).
Remove the camshaft timing pin and the crankshaft timing pin.
Use Tooling (A) in order to tighten bolt (4) to a torque of 2000 275 N m (1480 200 lb ft).
Carefully hit bolt (4) with a rubber mallet. Repeat Step 11. Repeat this procedure until the torque does not change.
Loosen the locking guide on the manual barring group. Verify the relation between the crankshaft and the camshaft. This is done by installing the timing pins. If both of the timing pins cannot be installed, loosen bolt (4) and camshaft drive gear (1) . Repeat the installation procedure for the camshaft drive gear.
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.
Adjust the valve clearance and the fuel timing.End By: Install the magneto. Refer to Disassembly and Assembly, "Magneto - Install".
