Use clean 15W-40 oil to lubricate the ball end of the push rods.

NOTE: The injector push rods (1) are larger in diameter than the valve push rods (2).

Install the push rods into the corresponding numbered location.

Inspect the adjusting screw. The contact area must be smooth with an even seating pattern.

If parallel scratches are found in the contact area, the adjusting screw must be replaced. This condition is normally found with worn push rods that will also require replacement.

CAUTION  If the adjusting screws protrude beyond the maximum listed below, the push rods can be damaged when the housing capscrews are tightened. Do not attempt to install the rocker lever shaft assemblies again without resetting the lash.

Loosen the rocker lever adjusting screws so there is a maximum of 32.0 mm [1.25 in] from the top surface of the lever and the ball end of the adjusting screw.

Install the rocker lever cover gasket. The rocker lever cover gaskets can be used again if not damaged.
