TESTING AND ADJUSTING
6.
Make sure the top surfaces of injector follower
(5) and shoulder (6) are clean and dry.
7.
Put 6V3075 Dial Indicator (2) and 6V3118
Timing Fixture (4) in position on the injector to be
checked.  Make sure the angle of the timing
fixture is on the top surface of follower (5) and
the extension rod is on the top surface of injector
shoulder (6) as shown in illustration.
FUEL TIMING TOOLS IN POSITION
13.
Turn the adjustment screw until zero is read on
the dial indicator. Tighten the adjustment screw
locknut to a torque of 70 15 N-m (50 11 lb. ft.)
and check adjustment again. If necessary, do
this procedure again until the adjustment is
correct.
FUEL TIMING TOOLS IN POSITION
2. 6V3075 Dial Indicator (metric). 4.6V3118 Timing
Fixture. 5. Injector follower. 6. Shoulder on injector
body.
ADJUSTMENT OF FUEL TIMING
The dial indicator pointers must indicate 0.00

14.
Remove the timing bolt from the flywheel when
the fuel timing check is completed.
0.20 mm.
9.
If the dial indicator pointers indicate zero, or are
within the tolerance given in Step 8, no
adjustment is necessary. Proceed to Step 14.
10.
If the dial indicator pointers do not indicate 0.00

0.20 mm, do Steps 11 through 14.
Tools Needed:
6V3119 Rack Synchronizing Gauge.
11.
Loosen the push rod adjustment screw locknut
for the injector to be adjusted.
Injector synchronization is the setting of all
injector racks to a reference position so each injector

gives the same amount of fuel to each cylinder. This is
Timing Fixture (4) in position on the injector to be
done by setting each injector rack to the same position
adjusted.  Make sure that both edges of the
while the control linkage is in a fixed position (called the
angle of the timing fixture sets flat on the top
synchronizing position). The procedure for adjustment of
surface of follower (5), and the extension rod is
injector synchronization is as follows:
on the top surface of injector shoulder (6).
