Adjusting Timing:
(14) Remove the oil filler tube (Fig. 53) and
adapter elbow from the front of the timing gear hous­
ing.
Fig. 58 Oil Filler Tube
(15) Loosen the injection pump shaft nut (use the
barring tool to keep the engine from rotating). Before
removing pump nut or washer, place a magnet to the
end of the injection pump shaft (Fig. 54). This will
prevent the nut or washer from falling into the tim­
ing gear cover which will require engine disassembly
for recovery.
(16) Position a magnet to the end of the injection
pump shaft. Install the special bearing and thrust
washer kit #6862 (Fig. 55) over th^ injection pump
shaft in this order: 1 thrust washer-1 bearing-1
thrust washer. The thrust washer/bearing kit is used
to prevent the pump gear from rotating on the pump
shaft when tightening the pump nut (step 22). Rein­
stall pump shaft nut allowing some clearance be­
tween the thrust washers. Do not tighten nut at this
time.
(17) Slowly rotate the engine clockwise until reach­
ing the required lift setting on the dial indicator (re­
fer to charts figure 51 or 52). The injection pump
should rotate with the engine since the injection
pump gear is still locked to the injection pump shaft.
(18) With the injection pump at the correct plunger
lift setting, use special gear puller tool #L-4407A to
pull the injection pump gear off the taper of the in­
jection pump input shaft. Leave the gear puller in­
stalled (Fig. 56). After the gear has been pulled,
ensure the lift setting has not changed.
(19) Rotate the engine 20 to 30 degrees counter­
clockwise, then rotate the engine back clockwise to
TDC (Fig. 57). This removes backlash from the
geartrain.
(20) Loosen, but do not remove the gear puller tool
bolts. Using the gear puller, rotate to pump gear
counterclockwise by hand (Fig. 58), while pushing

the gear onto the pump shaft. This will remove back­
lash between the injection pump and camshaft gears.
(21) Hand tighten the pump shaft nut (Fig. 59).
Remove the gear puller (Fig. 59).
(22) Tighten the pump shaft nut to 15 N-m (11 lb.
ft.) torque to seat the gear to the pump shaft taper
(Fig. 60).
(23) Remove injection pump shaft nut. Use a mag­
net on the end of the shaft while removing (Fig. 54).
(24) Remove special bearing and thrust washers
#6862 from pump shaft. Use a magnet on the end of
the shaft while removing.
(25) While preventing the engine from rotating
with the barring tool, tighten the shaft nut to 195
N-m (144 lb. ft.) torque (Fig. 60).
(26) Repeat steps 12 and 13 to verify that the final
timing setting is correct. If the setting is not correct,
repeat steps 15 through 25.
