PLATE AS 4890093 - Caterpillar

Illustration 4 g03711142
Install thrust washers (10) and bolts (9) that fasten the camshaft to the engine.
If the camshaft is out of time more than 18 degrees (approximately 1/2 of the timing pin is out of the groove), the valves can make contact with the pistons. This will cause damage to the engine. Refer to Testing and Adjusting, "Camshaft Timing" for more information.
Illustration 5 g03711143
Remove timing pin (16) from the storage position on the side of the engine.
Turn the camshaft until timing pin (16) can be installed through the cylinder block and into groove (17) that is in the camshaft.
Repeat Steps 15 and 16 for the camshaft on the opposite side of the engine.

Use the following procedure in order to install camshaft drive gears (8).
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 (8) 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 (7).
Install the bolt and timing ring (11). 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 18.h and 18.i until the Mark has turned at least 90 degrees.

Remove the timing pins from the camshafts. Install timing pins (16) in the original locations.
Illustration 10 g03710997
Install the gaskets and covers (6) over the camshaft drive gears on both sides of the engine.
Illustration 11 g03711376
