Document Title Adjusting engine valve and injectors Function Group 214 Information Type Service Information Date 2014/7/1 0
Profile Profile Profile 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

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.

• 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.

Figure 3 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 153624
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. Injector and valve adjustment sequence

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.
10
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.
Figure 7 Position, valve Loosen the injector
adjusting screw locknut 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 correctly

spring retainer washer touches the top stop screw.
Figure 9 Adjustment, injector
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 Nm (5 6 lbin)

• 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

• 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 Nm (6 lbin)
• Touch method
• Tighten the adjusting screw until a light drag is
  felt on the feeler gauge.

• Figure 13
• Adjusting, valve clearance
• Hold the adjusting screw in this position. The
  adjusting screw must not turn when the locknut is
  tightened. Tighten the locknut.
• Tightening torque
• Without torque wrench adapter 61 Nm (45

• With torque wrench adapter (1) (Part no.
  St669) 47 Nm (35 lbfft)

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
crosshead and the
14
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
brakeadjustment 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.
Figure 17 Marking, 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. Injector and valve

• Fuel filling pump, description
• The pump outlet is plumbed directly to the fuel
  tank to reduce the risk of introducing
  contamination.
• The master switch must be in the ON position to
  operate the fuel filling pump.

CAUTION
The filter at the end of fuel filling pump inlet
hose is a strainer, and will not filter
impurities from the fuel. When filling use CLEAN
fuel only!
CAUTION
Do not operate the fuel filling pump without fuel
or for extended periods of time.
CAUTION
Drain the fuel from the suction hose before
putting it in the storage compartment.
CAUTION
In case of the pump has been disassembled,
assemble the pump so the that the sharp portion
of the vane faces the counterclockwise direction.
