The engine is a 6-cylinder, 4-stroke, direct injected, turbocharged, water cooled assembly with a cast iron block and
cylinder head.
Gears in the engine gear case are hardened helical type for strength and reduced noise, arranged to provide quiet,
smooth transmission of power.
The cylinder block and head are designed with internal passages formed as sets for lubrication and cooling. The
water pump and oil cooler are integrally mounted.
The fan belt is a poly type V-belt for improved performance.

Profile:
Adjusting engine valve and injectors
Valves and injectors must be correctly adjusted for the engine to operate efficiently. Valve and injector adjustment must be
performed using the values listed in this section. The table gives the adjustment limits for fixed timed engines.
Adjust the valves and the injectors at each 1500 hours or 1 year maintenance interval. If the valves and injectors have been
adjusted during troubleshooting or before the 1500 hours or 1 year scheduled maintenance interval, adjustment is not
required at this time.
Valve and injector adjustment limits
Valve and injector Adjustment Limits
“Top stop” Injector Preload : 0.6 ~ 0.7 N·m
Intake valve mm 0.35 0.014
Exhaust valve in 0.68 0.027
All overhead valve and injector adjustments must be made when the engine is cold, and stabilized coolant temperature is 60
°C (140 °F) or below.

8. Each cylinder has three rocker levers :



The long rocker lever (E) is the exhaust lever.
The center rocker lever is the injector lever.
The short rocker lever (I) is the intake lever.
Refer to the figure for valve rocker lever locations.

The crankshaft rotation is clockwise when viewed from the front of the engine.
The cylinders are numbered from the front gear cover end of the engine.
The engine firing order is 1–5–3–6–2–4
Figure 4
The engine firing order
The valves and injectors on the same cylinders are not adjusted at the same index mark on the accessory drive pulley on
fixed timed engines.
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 injectors.

WARNING
Do not pull or pry on the fan to manually rotate the crankshaft. To do so can damage the fan blades. Damaged fan
blades can cause premature fan failures which can result in serious personal injury or property damage.
The valve set marks are located on the accessory drive pulley. The marks align with a pointer on the gear cover.
Use the accessory drive shaft to rotate the crankshaft.

9. Figure 5
Rotation, crankshaft
The adjustment can begin on any valve set mark. In the following example the adjustment will begin on the ‘A’ valve set
mark with cylinder No. 5 valves closed and cylinder No. 3 injector ready for adjustment.
Rotate the accessory drive shaft clockwise until the ‘A’ valve set mark on the accessory drive pulley is aligned with the
pointer on the gear cover.
Figure 6
Position, valve mark
When the ‘A’ mark is aligned with the pointer, the intake and exhaust valves for cylinder No. 5 must be closed. If these
conditions are correct, cylinder No. 4 injector and cylinder No. 2 valves are ready to set.
Both valves are closed when both rockers are loose, and can be moved from side to side.

CAUTION
An over-tightened setting on the injector adjusting screw will produce increased stress on the injector train and the
camshaft injector lobe which can result in engine damage. Use torque wrench to tighten the adjusting screw.
Tightening torque : 0.6 ~ 0.7 N·m (5 ~6 lb·in)

Figure 12
Checking, clearance
Two different methods for establishing valve lash clearance are described below. Either method can be used, however, the
torque wrench method has proven to be the most consistent. It eliminated the need to feel the drag on the feeler gauge.
 Torque wrench method :

12. Use the inch pound torque wrench, (Part No. 3376592) (Normally used to set preload on top stop injectors) and tighten the
adjusting screw.
Tightening torque : 0.7 N·m (6 lb·in)
 Touch method :
Tighten the adjusting screw until a light drag is felt on the feeler gauge.

Hold the adjusting screw in this position. The adjusting screw must not turn when the locknut is tightened.

With torque wrench adapter (1) :
(Part no. St–669) 47 N·m (35 lbf·ft)
Figure 14
Tightening torque, locknut
After tightening the locknut to the correct torque value, check to make sure the feeler gauge will slide backward and forward
between the cross– 4head and the rocker lever with only a slight drag.
Figure 15
Checking, locknut torque
If using the touch method, attempt to insert a feeler gauge that is 0.03 mm (0.001 in) thick between the cross–head and the

13. rocker lever pad. The valve lash is not correct when a thicker feeler gauge will fit.
Figure 16
Checking, valve lash
Adjust the jacobs engine brake, if applicable, after adjusting the valves before rotating the accessory drive pulley to the next
index mark.
Refer to jacobs engine brake–adjustment following this procedure.
After adjusting the valves, rotate the accessory drive and align the next valve set mark on the accessory drive pulley with the
pointer on the gear cover.

Adjust the appropriate injector and valves following the injector and valve adjustment sequence chart.
Repeat the process to adjust all injectors and valves.
After adjusting all the valves and injectors, check the torque on the adjusting screw locknuts to make sure none were
overlooked.
