Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Do not turn the crankshaft or the camshaft while the camshaft gear is removed. If the front gear group is not correctly timed during installation, interference can occur between the pistons and the valves, resulting in damage to the engine.
Note: Refer to Engine News, 27, March 2006, "Sealing and Installing the Flywheel Housing" for more information.
Ensure that the mating surfaces of the flywheel housing and the engine block are clean. Both mating surfaces must be clean, dry, and free of any oil before Tooling (F) is applied.

Apply a 6.0 mm (0.25 inch) bead of Tooling (F) to the mating surface of the flywheel housing. Refer to Illustration 1.

Install Tooling (D) into the cylinder block.
Install Tooling (C) and a suitable lifting device on flywheel housing (16). The weight of flywheel housing (16) is approximately 235 kg (518 lb).
Lift the flywheel housing into position onto Tooling (D).
Install bolts (17) and the hard washers that secure the flywheel housing to the cylinder block. Remove Tooling (D) and install remaining bolts (17) and the hard washers.Note: Refer to Parts Manual for the correct positions for bolts that secure the flywheel housing to the cylinder block.
Tighten bolts (17) evenly. Tighten the 1/2 - NC bolts to a torque of 135 20 N m (100 15 lb ft). Tighten the 5/8 - NC bolts to a torque of 270 40 N m (200 30 lb ft).
Tighten plugs (15) to a torque of 70 15 N m (50 11 lb ft).
Install the crankshaft rear seal and the wear sleeve. Refer to Disassembly and Assembly, "Crankshaft Rear Seal and Wear Sleeve - Install".

Use the following procedure to install camshaft drive gear (11) and camshaft drive gear (14).
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 gear (11) and camshaft drive gear (14) 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 (9) and plate (10).
Install bolt (12) and ring (13). Ensure that the hole in the ring is properly seated on the locating pin.
Tighten the bolt to a torque of 360 N m (265 lb ft).
Place a mark on the bolt.
Place a driver against the retaining plate of the camshaft drive gear. Strike the driver with a hammer, three times, or four times.
Tighten the bolt again to a torque of 360 N m (265 lb ft).
Repeat Steps 11.h and 11.i until the mark has turned at least 90 degrees.
