Remove the rear camshaft covers from both sides of the engine. Timing Check Procedure
Refer to Testing and Adjusting, "Finding the Top Center Position for the No. 1 Piston". Note: When the timing bolt is installed, it is not necessary to remove the No. 1 valve cover in order to find the compression stroke. Both of the rear camshaft covers must be removed in order to check the timing.
When the timing bolt is installed in the flywheel, look at the rear end of the camshaft. If the timing ring is visible, then the No. 1 piston is on the compression stroke. If the timing ring is not visible, then feel the back of the camshaft for the groove. If the groove is at the back of the camshaft, the flywheel must be turned by 360 degrees. Turning the flywheel for 360 degrees will put the No. 1 piston on the compression stroke.

Installation of timing pins (typical example)

(3) RH Camshaft
Remove timing pins (2) from the storage positions after the timing bolt is installed in the flywheel. The engine must be on the No. 1 piston is on the compression stroke.
Install timing pins (2) through timing holes (1) in the engine block. Install timing pins (2) into the groove in camshaft (3) on each side of the engine. In order to time the engine correctly, the timing pins must fit into the groove of each camshaft.
If timing pins (2) do not engage in the grooves of both camshafts, the engine is not in time. One camshaft or both camshafts must be adjusted.
Both camshafts are adjusted in the same manner. Refer to "Adjustment Procedure" for the procedure to put the camshafts in time with the crankshaft.
If a camshaft is out of time more than 18 degrees (approximately 1/2 the diameter of timing pin out of groove), the valves can make contact with the pistons. This will cause damage that will make engine repair necessary.
Adjustment Procedure
Note: The timing must be checked before the timing adjustments are made. See "Timing Check Procedure" for the procedure.After the Timing Check procedure is complete, the timing bolt will be engaged in the flywheel. The No. 1 piston will be at the top center (TC) position.

(5) Bolt
Remove all of the valve covers on the side for the camshaft adjustment. Loosen bolts (1) that hold rocker shafts (2) to the valve cover bases until all rocker arms are free from the injectors and the valves. Note: The above procedure must be done before camshaft drive gear (3) is pulled off the camshaft taper.
Remove the covers from the flywheel housing.
