MAINTENANCE VEHICLE EXTERIOR
CHECK/ADJUST HEADLAMP ALIGNMENT
Check/adjust headlamp and auxiliary alignment.
CHECK FRONT WHEEL ALIGNMENT
Use recognised wheel alignment equipment to
perform this check and adjustment.
See STEERING,
Adjustment, Front Wheel Alignment
REMOVE WHEELS, CHECK TYRES
Check tyres (including spare) for compliance with
manufacturers' specification.
Check visually for cuts, lumps, bulges, uneven tread
wear and tread depth. Check road wheels for
damage.
Check/adjust tyre pressures.
CHECK/TIGHTEN TOWING BRACKET FITTINGSINSPECT BRAKE PADS FOR WEAR, CALIPERS
FOR LEAKS AND CONDITION
Check thickness of brake pads, fit new pads if
minimum thickness is less than 3,0mm. Check brake
pads for oil contamination. If new brake pads required.
See BRAKES, Repair, Front Brake Pads
or.See BRAKES, Repair, Rear Brake Pads
WARNING: When renewing brake pads, it
is essential that only genuine components
with correct grade of lining are used.
Always fit new pads as complete axle sets, NEVER
individually or as a single wheel set. Serious
consequences could result from out of balance
braking due to mixing of linings.
Refit road wheels
Fit road wheels in original hub position. Secure in
position with wheel nuts, do not fully tighten wheel
nuts at this stage, lower vehicle and finally tighten
wheel nuts to correct torque.
Alloy wheels:
130 Nm.
Steel wheels:130 Nm.

REPAIR Timing belt fitting and tensioning
NOTE: It is important that belt tensioning
is carried out carefully and accurately. The
following procedure involves tensioning
the belt twice to ensure that it is equally tensioned
between each gear. New and original belts are
tensioned to different figures.
28.Ensure timing marks are correctly aligned, pin
from special tool LRT-12-045 is correctly
inserted in injection pump gear and timing tool
LRT-12-044 (LRT-12-085 if EDC) is fitted to
flywheel housing with pin located in flywheel slot.
Or if automatic: Timing tool LRT-12-044 is fitted
to engine backplate and pin located in ring gear.
29.Fit belt observing rotational marks made during
removal. Feed belt over gears keeping it tight on
drive side.
30.Fit idler pulley.
31.Slacken injection pump gear retaining bolts.
32.Adjust belt to correctly sit in gears.
33.Slacken belt tensioner securing bolt to finger
tight.
34.Insert 13 mm square drive extension bar in
tensioner plate.
NOTE: Belt tensioning should be carried
out using a dial type torque meter having a
range not exceeding
60 Nm.The torque
meter should be used in the almost vertical
position.
35.Apply a tension of
14 to 16 Nmfor a new belt or
11 to 13 Nmfor an original belt. When tension
is correct tighten clamp bolt.
36.Tighten injection pump gear bolts.
37.Remove pin from injection pump gear.
38.Disengage timing pin from timing slot in flywheel
or ring gear.
39.Rotate crankshaft one and three quarter turns in
a clockwise direction; then continue rotation until
timing pin in timing tool can be engaged with slot
in flywheel or ring gear.
40.Disengage timing pin.
41.Insert pin from special tool LRT-12-045 in
injection pump gear and through into pump
flange.
42.Slacken injection pump gear retaining bolts.
43.Slacken tensioner and retension belt.
44.Tighten injection pump gear retaining bolts.
45.Remove pin from injection pump gear.
46.Remove timing tool and refit plug.
47.Fit front cover plate using new gaskets.

groove in new housing and seal assembly.
9.Fit new assembly, with former/guide in-situ, over
crankshaft flange, this action will eject
former/guide.
10.Secure assembly to cylinder block with five bolts
tightened to correct torque, removing slave studs
individually and inserting bolts.
11.Refit flywheel.

4.Remove flywheel.See Flywheel
5.Remove bearing bush.
NOTE: The bearing bush can be removed
by using one of the following methods.
Method 1.
Obtain a short length of steel rod of a diameter having
a good slide fit in the bore of the bush. Pack the bore
with grease and insert the steel rod into the end of the
bore, give a sharp blow with a hammer and the
grease should drive out the bush. It is recommended
that the bush and rod be covered by a suitable cloth
or rag to prevent grease from splashing.

REPAIR
CAUTION: Ease timing belt off gears using
fingers only. Metal levers may damage the
belt and gears. Do not rotate engine with
timing belt removed and cylinder head fitted.
Timing belts must be stored and handled with
care. Always store a timing belt on its edge with a
bend radius greater than 50 mm. Do not use a
timing belt which has been twisted or bent double
as this can fracture reinforcing fibres. Do not use
an oil contaminated timing belt. Although the belt
has a service life of 96,000 miles, 160,000 km, an
existing belt should only be refitted if it has
completed less than 48,000 miles, 80,000 km.
