Check the valve rocker levers on cylinder No. 5 to see if

both the intake and exhaust valves are closed.

NOTE: Both the intake and exhaust valves are closed when

both rocker levers are loose and can be moved from side to

side. If both valves are not closed, rotate the accessory drive

one complete revolution; and align the ‘‘A’’ mark with the

pointer again.

If the valve rocker lever adjusting screws have been loos-

ened and not yet adjusted, watch the valve push tubes

as the engine rolls upon the ‘‘A’’ mark. Both valve push

tubes will have moved to the downward (valve closed)

position if the engine is on the correct stroke.

Loosen the lock nut on the injector adjusting screw on

cylinder No. 3. Tighten the adjusting screw until all the

clearance is removed from the injector train.

Tighten the adjusting screw one additional turn to cor-

rectly seat the link.

Loosen the injector adjusting screw until the injector

rocker lever is loose or has a small amount of lash. When

the rocker lever is loose, the STC injector tappet is touch-

ing the top of the injector.

Place STC tappet adjusting tool, Part No. 3823348, on

the upper surface of the STC injector top-cap. Rotate the

tool around the tappet until the tool’s locating pin is in-

serted into one of the four holes in the top of the tappet.
