The valves and the injectors on the same cylinder are

adjusted at the same index mark on the accessory drive

pulley.

One pair of valves and one injector are adjusted at each

pulley index mark before rotating the accessory drive to

the next index mark.

Two crankshaft revolutions are required to adjust all the

valves and the injectors.

Rotate the accessory drive in the direction of engine

rotation. The accessory drive will rotate clockwise on a

right hand engine, when looking at the front of the engine.

Align the ‘‘A’’ mark on the accessory drive pulley with the

pointer on the gear cover.

Check the valve rocker levers on cylinder No. 1 to see if

both valves are closed.

NOTE: Both 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 revo-

lution; 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 injector adjusting screw lock nut on cylinder

No. 1. Bottom the injector plunger by tightening and

loosening the adjusting screw 2.8 N•m [25 in-lb] three or

four times to remove the fuel.

NOTE: Do not bottom the plunger any tighter than 2.8 N•m

[25 in-lb] when removing the excess fuel.
