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. 43).
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).

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.
(6) 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.
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove vacuum line at vacuum pump (Fig.
44).
NOTE: Observe position of driver on rear of pump.
(3) Remove vacuum pump and seals (Fig. 44)
(4) Clean all sealing surfaces.
