INSTALLATION
(1) Install oil pan. Apply a continuous 3 mm bead
of Silicone Sealer to oil pan, install within 10 min-
utes.
(2) Install oil pan bolts and torque bolts to 11 N´m
(8 ft. lbs.).
(3) Install oil drain plug tighten to 79 N´m (58 ft.
lbs).
(4) Lower vehicle.
(5) Fill engine with proper amount of oil.
(6) Connect battery cable.
OIL PUMP
REMOVAL
(1) Raise vehicle on hoist.
(2) Remove right splash shield.
(3) Remove both accessory drive belts. Refer to
Group 7, Cooling.
(4) Remove pump shaft support bracket assembly.
(5) Remove vibration damper. Refer to Vibration
Damper Removal in this section.
NOTE: Crankshaft damper nut is left handed
thread.
(6) Remove front cover. Refer to Timing Gear
Cover Removal in this section.
(7) Remove oil pump.
INSTALLATION
(1) Install new O-ring and lubricate with clean
engine oil.
(2) Install oil pump and tighten retaining screws
to 27.5 N´m (240 in. lbs.).(3) Install front cover. Refer to Timing Gear Cover
Installation in this section.
(4) Install pump shaft support bracket assembly.
CAUTION: Correct torque on the vibration damper
nut is important or engine damage can occur.
(5) Install vibration damper. Torque nut to 441
N´m (325 ft. lbs.)

OIL PUMP PRESSURE RELIEF VALVE
REMOVAL
(1) Remove oil pan.
(2) Remove clip retaining relief valve.
(3) Remove relief valve cap, spring, and plunger
(Fig. 50).
(4) Check relief valve spring length. Relief valve
spring free length is 57.5mm (2.263 in.). If spring
length is less or spring is distorted it must be
replaced.
(5) Check plunger for scoring, replace if necessary.
INSTALLATION
(1) Thoroughly clean all components and relief
valve pocket in cylinder block.
(2) Fit plunger, spring and cap into block.

REMOVAL AND INSTALLATION (Continued)

(14) Gauge reading should be at 0.60 mm. If not,
the pump must be rotated for adjustment:
(a) Loosen the three injection pump mounting
nuts at the mounting flanges. These flanges are
equipped with slotted holes. The slotted holes are
used to rotate and position the injection pump for
fuel timing. Loosen the three nuts just enough to
rotate the pump.
(b) Rotate the pumpclockwise(as viewed from
front) until .60 mm is indicated on the dial indica-
tor gauge.
(c) Tighten the three pump mounting nuts to 30
N´m (22 ft. lbs.) torque.
(d) Recheck the dial indicator after tightening
the pump mounting nuts. Gauge should still be
reading 0.60 mm. Loosen pump mounting nuts and
readjust if necessary.
(15) Remove dial indicator and adapter tools.
(16) Install access plug and washer to rear of
injection pump.
(17) Install plug at timing gear cover.
(18) Remove dial indicator from valve stem.
(19) Install valve spring and keepers.
(20) Install rocker arm assembly and tighten nuts.
(21) Install and connect the four high±pressure
fuel lines to the fuel injection pump. Also connect
fuel lines at the fuel injectors. For procedures, refer
to High±Pressure Fuel Lines in this group.
(22) Install electrical connector at engine coolant
temperature sensor.
(23) Connect electrical connector at fuel shutdown
solenoid.(24) Connect the main engine wiring harness to
the glow plugs.
(25) Connect the fuel timing solenoid pigtail har-
ness to the engine wiring harness.
(26) Connect the overflow valve/banjo fitting (fuel
return line assembly). Replace copper gaskets before
installing.
(27) Connect the rubber fuel return and supply
hoses to metal lines at pump. Tighten hose clamps to
2 N´m (20 in. lbs.) torque.
(28) Install generator assembly.
(29) Install engine accessory drive belt. Refer to
Group 7, Cooling System for procedures.
(30) Install negative battery cable to battery.
(31) Start the engine and bring to normal operat-
ing temperature.
(32) Check for fuel leaks.
FUEL INJECTORS
Four fuel injectors are used on each engine. Of these
four, two different types are used. The fuel injector used
on cylinder number one is equipped with a fuel injector
sensor (Fig. 47). The other three fuel injectors are iden-
tical.
Do not place the fuel injector equipped with
the fuel injector sensor into any other location
except the cylinder number one position.
REMOVAL
(1) Disconnect negative battery cable at battery.
(2) Thoroughly clean the area around the injector
with compressed air.
(3) Remove the fuel drain hoses (tubes) at each
injector (Fig. 48) being serviced. Each of these hoses
is slip±fit to the fitting on injector.
(4) Remove the high±pressure fuel line at injector
being removed. Refer to High±Pressure Fuel Lines in
this group for procedures.
(5) Remove the injector using special socket tool
number VM.1012A. When removing cylinder number
