Apply Tooling (D) to the mating surface of the flywheel housing. Refer to Illustration 7.
Use the following procedure to install camshaft drive gears (6).
Clean the taper of the camshaft and the tapered bore of the camshaft gear with a lint free cloth saturated with solvent to remove oil. Clean the parts again with a lint free alcohol wipe to remove any residue. The alcohol wipe will dirty after cleaning the parts. Clean the parts again with a lint free alcohol wipe until no residue is left on the alcohol wipe.Note: The taper of the camshaft and the tapered bore of the camshaft gear must be clean, dry, and free of residue before assembly.
Ensure that the camshaft timing pins and the timing pin for the flywheel are installed.
Place camshaft drive gears (6) in position. Remove the backlash by rotating the gears in the opposite direction of camshaft rotation.Note: For "Standard Rotation" engines, turn the camshaft drive gears COUNTERCLOCKWISE. For "Reverse Rotation" engines, turn the camshaft drive gears CLOCKWISE.
Install bolt (4) and plate (5) for the camshafts.
Install bolt (3) and the timing ring for the camshafts. Ensure that the hole in the timing ring is properly seated on the locating pin.
Tighten bolt (4) and bolt (3) to a torque of 360 N m (265 lb ft).
Place a Mark on the bolts.
Place a driver against the retaining plate of the camshaft gear. Strike the driver solidly with a hammer 3 to 4 times.
Tighten bolt (4) and bolt (3) again to a torque of 360 N m (265 lb ft).
