All overhead (valve and injector) adjustments must be

made when the engine is cold (any stabilized coolant

temperature at 60°C [140°F] or below).

Each cylinder has three rocker levers:

• The exhaust rocker lever (1).

• The injector rocker lever (2).

• The intake rocker lever (3).

The two levers closest to the center of each rocker hous-

ing are the intake rocker levers. The two levers closest to

the ends of the rocker housing are the exhaust rocker

levers.

The valves and the injectors on the same cylinder are not

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,ona

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.
