(5) Remove the belt pulley/vibration damper (Fig.
47).
NOTE: If grooves can be felt in the belt pulley/vibra-
tion damper during inspection, the pulley/damper
must be replaced.
(6) Inspect hub at belt pulley/vibration damper for
wear grooves.
(7) Replace front crankshaft seal.
INSTALLATION
NOTE: Align parallel key, fix in place with grease.
Turn to ensure the slot is aligned with parallel key
in crankshaft.
NOTE: Front crankshaft seal must be replaced
before installing the belt pulley/vibration damper.
(1) Position the belt pulley/vibration damper.(2) Install crankshaft center bolt and washer.
Tighten bolt in two stages. M8.8 bolt to 200N´m (148
lbs. ft.) then 90É, M10.9 bolt to 325N´m (240 lbs. ft.)
then 90É.
(3) Remove the retaining lock for the crankshaft/
ring gear (Fig. 47).
NOTE: Inspect accessory drive belt for wear.
Replace as necessary.
(4) Install accessory drive belt (Refer to 7 - COOL-
ING/ACCESSORY DRIVE/DRIVE BELTS - INSTAL-
LATION).
(5) Install the additional A/C compressor drive belt
(if equipped).
(6) Install the coolant module (if equipped with the
additional A/C compressor).
(7) Reconnect negative battery cable.
WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS IN OPERATION. DO NOT STAND IN A
DIRECT LINE WITH THE FAN. DO NOT PUT YOUR
HANDS NEAR THE PULLEYS, BELTS OR FAN. DO
NOT WEAR LOOSE CLOTHING.
(8) Start vehicle and inspect for leaks.
VACUUM PUMP
DESCRIPTION
The vacuum pump is operated by a slotted exten-
sion attached to the vacuum pump shaft. The vac-
uum pump shaft slotted extension fits into, and is
driven by, the exhaust camshaft gear.
The vacuum pump is a constant displacement,
vane-type pump. Vacuum is generated by vanes
mounted in the pump rotor. The rotor is located in
the pump housing and is pressed onto the pump
shaft.
The vacuum pump rotating components are inter-
nally lubricated.
The vacuum pump is not serviceable and must be
replaced as a unit. Do not disassemble or attempt to
repair the pump.
OPERATION
Vacuum pump output is transmitted to the Heater,
Electronic, Vacuum, Air Conditioner (HEVAC) and
speed control, systems through a supply hose. The
hose is connected to an outlet port on the pump hous-
ing and uses an in-line check valve to retain system
vacuum when vehicle is not running.
Pump output ranges from a minimum of 8.5 to 25
inches vacuum.
The pump rotor and vanes are rotated by the pump
drive gear. The drive gear is operated by the exhaust
camshaft gear.

(7) Connect a scan tool, select from Main Menu,
System Select, Engine, System Tests, Fuel Quantity
Test, Engine Cranking Test and follow the screen.
(8) After ten seconds, a maximum of 2.5 ml
(between2&3graduation lines) may be reached in
the inner vials. If the level has exceeded the 2.5 ml,
replace that affected cylinder's injector, clear the
memory using the scan tool, empty the test vials, and
retest.
RUNNING TEST
NOTE: If an injector is found to be out of specifica-
tion, repeat this test procedure after the injector
replacement. Hydraulic flow will take the path of
least resistance and multiple failures may be identi-
fied. Engine temperature must be above 80É C
(176ÉF) to perform the running test.
Perform this test with the engine at operating tem-
perature. This test will assist in determining a defec-
tive or internally leaking injector(s) is present by
measuring the amount of fuel return.
(1) Turn the ignition off.
(2) Remove the engine cover (Refer to 9 - ENGINE
- REMOVAL).
(3) Disconnect the fuel return hoses at the top of
the injectors.
(4) Pinch off the fuel return line at the banjo bolt
fitting of the fuel rail.
(5) Install the test vials onto the injectors and
secure with the return hose clips (Fig. 2).
(6) Connect a scan tool, select from Main Menu,
System Select, Engine, System Tests, Fuel Quantity
Test, Engine Running Test and follow the screen.
(7) After ten seconds, a maximum of five gradua-
tion lines (40 ml) of the large test vial may bereached. If the level has exceeded the five graduation
line, replace that affected cylinder's injector, clear the
memory using the scan tool, empty the test vials, and
retest.
STANDARD PROCEDURE
STANDARD PROCEDURES - CLEANING FUEL
SYSTEM COMPONENTS
CAUTION: Cleanliness cannot be overemphasized
when handling or replacing diesel fuel system com-
ponents. This especially includes the fuel injectors,
high-pressure fuel lines, fuel rail, and fuel injection
pump. Very tight tolerances are used with these
parts. Dirt contamination could cause rapid part
wear and possible plugging of fuel injector nozzle
tip holes. This in turn could lead to possible engine
misfire. Always wash/clean any fuel system compo-
nent thoroughly before disassembly and then air
dry. DO NOT wire brush injector nozzles when
cleaning. Cap or cover any open part after disas-
sembly. Before assembly, examine each part for
dirt, grease or other contaminants and clean if nec-
essary. When installing new parts, lubricate them
with clean engine oil or clean diesel fuel only.
STANDARD PROCEDURES - DRAINING WATER
FROM FUEL FILTER
Connect a hose to the Water in Fuel (WIF) drain
and place it in a clearly marked and suitable con-
tainer. Open the WIF drain by turning counterclock-
wise (Fig. 3). Turn the ignition key on for 20 seconds
(Refer to low pressure fuel pump operation). Repeat
the procedure until all water is removed, close the
drain and remove the hose.
