Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Refer to Engine News, 27, March 2006, "Sealing and Installing the Flywheel Housing" for more information.
Ensure that the mating surface of the flywheel housing and the engine block are clean. Both mating surfaces must be clean, dry, and free of any oil before Tooling (D) is applied.
Illustration 1 g01258819
Apply a 6.0 mm (0.25 inch) bead of Tooling (D) to the mating surface of the flywheel housing. Refer to Illustration 1.
Illustration 2 g00588658
Typical example
Use Tooling (B) and a suitable lifting device to the top of flywheel housing (2). The weight of flywheel housing (2) is approximately 210 kg (460 lb).
Position flywheel housing (2) on the engine.
If the dowel pins were removed from flywheel housing (2), install the dowel pins and ensure that the dowel pins are properly seated.

Install the bolts and the hard washers for flywheel housing (2). Refer to Illustration 3 for the proper locations of the bolts. 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).
Remove Tooling (B).
Install the crankshaft rear seal and the wear sleeve. Refer to Disassembly and Assembly, "Crankshaft Rear Seal and Wear Sleeve - Install".
Place the camshaft timing pins in position. Place the timing bolt in the flywheel with the No. 1 piston at the top center position on the compression stroke.

Use the following procedure in order to install camshaft drive gears (4).
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 in order 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 (4) 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 the bolt and plate (5).
Install the bolt and timing ring (3). Ensure that the hole in the timing 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 gear. Strike the driver solidly with a hammer 3 to 4 times.
Tighten the bolt again to a torque of 360 N m (265 lb ft).
Repeat Steps 10.h and 10.i until the Mark has turned at least 90 degrees. Note: Refer to the Disassembly and Assembly, "Camshaft - Install" for more information.
Remove the timing pins from the camshafts and the flywheel.
