19FUEL SYSTEM
2
DESCRIPTION AND OPERATION DESCRIPTION
General
The fuel delivery system comprises a fuel tank, fuel pump, fuel pressure regulator, five injectors and a fuel filter.
The system is controlled by the ECM, which energises the fuel pump relay and controls the operation and timing
of each injector solenoid.
Unlike other Diesel engines, the Td5 has no injection pump. The diesel direct injection system receives fuel at
pressure from a two stage fuel pump located in the fuel tank. The system incorporates a fuel return to the fuel
pump, via a fuel cooler attached to the inlet manifold, and a fuel filter. A fuel pressure regulator is located in a
housing on the rear of the cylinder head. The regulator maintains the fuel delivered to the injectors at a constant
pressure and returns excess fuel back to the fuel filter and pump via the fuel cooler.
A fuel filter is positioned on the chassis longitudinal, below the RH rear wheel arch. The fuel feed and return to and
from the engine passes through the filter. The filter also incorporates a water sensor, which illuminates a warning
lamp in the instrument pack.
A moulded fuel tank is located at the rear underside of the vehicle between the chassis longitudinals. The tank
provides the attachment for the fuel pump and the fuel gauge sender unit, which is located inside the tank.
Fuel Tank and Breather
The fuel tank and breather system is a major part of the fuel delivery system. The fuel tank and breathers are
located at the rear of the vehicle between the chassis longitudinals.
Fuel Tank
The moulded fuel tank is made from High Molecular Weight (HMW) High Density Polyethylene (HDPE), and is
manufactured using a proportion of recycled plastic.
The tank is held in position by a metal cradle which is secured to the chassis cross members by four bolts, two
holding the front of the cradle in position, two holding the rear. The fuel tank has a useable capacity of 75 litres
(16.5 gallons).
An aperture in the top surface of the tank allows for the fitment of the fuel pump and fuel gauge sender unit, which
is retained with a locking ring. A reflective metallic covering is attached to the tank with three scrivets to shield the
tank from heat generated by the exhaust system.
Fuel Tank Breather System
The fuel tank filler tube incorporates a tank vent which allows air and fuel vapour displaced from the tank when
filling to vent to atmosphere via the filler neck.
A breather spout within the tank controls the tank’Full’height. When fuel covers the spout it prevents fuel vapour
and air from escaping from the tank. This causes the fuel to’back-up’in the filler tube and shuts off the filler gun.
The position of the spout ensures that when the filler gun shuts off, a vapour space of approximately 10% of the
tanks total capacity remains. The vapour space ensures that the Roll Over Value (ROV) is always above the fuel
level and vapour can escape and allow the tank to breathe.
The ROV is welded to the top surface of the tank. It is connected by a tube to the filler tube, which in turn is
connected to the atmospheric vent pipe. The ROV allows fuel vapour to pass through it during normal vehicle
operation. In the event of the vehicle being overturned the valve shuts off, sealing the tank and preventing fuel
from spilling from the atmospheric vent pipe.

OVERHAUL
83.Position dial gauge centrally on pinion end face
with stylus registering on lowest point on one
differential bearing bore. Note dial gauge
deviation from zeroed setting.
84.Repeat on other bearing bore. Add together
readings, then halve sum to obtain mean
reading. Note whether stylus has moved up or
down from zeroed setting.
Example 1
Reading obtained LH side.............. + 0.1524mm
Reading obtained RH side............. - 0.0762mm
Add + 0.1524mm - 0.0762mm = + 0.0762mm
Divide by 2 (0.0762 divided by 2)= 0.0381mm
Therefore subtract 0.0381mm from shim thickness
behind pinion inner bearing track.
Example 2
Reading obtained LH side............. + 0.1524mm
Reading obtained RH side............ - 0.2032mm
Add + 0.1524mm - 0.2032mm = + 0.0508mm
Divide by 2 (0.0508 divided by 2)= 0.0254mm
Therefore add 0.0254mm from shim thickness behind
pinion inner bearing track.
Pinion height setting block LRT-54-503
85.Where stylus has moved down (85a), amount is
equivalent to thickness of shims that must be
removed from under pinion inner cup to bring
pinion down to nominal position. Where stylus
has moved up (85b), amount is equivalent to
additional thickness of shims required to bring
pinion up to nominal position.
Ensure that height marked 30.93 mm is used for this
differential.

OVERHAUL 86.Before adjusting shim thickness, check pinion
face marking and if it has a plus (+) figure,
subtract that from shim thickness figure obtained
in previous instruction. Alternatively if pinion has
a minus (-) figure, add amount to shim thickness
figure.
87.Adjust shim thickness under pinion inner cup as
necessary, by amount determined in instructions
85 and 86.
88.Recheck pinion height setting instructions 82 to
84. If setting is correct, mean reading on dial
gauge will agree with figure marked on pinion
end face. For example, with an end face marking
of +3, dial gauge reading should indicate that
pinion is 0.003 in (0.0762 mm) below nominal.
89.When pinion setting is satisfactory, temporarily
remove pinion outer bearing.
90.Fit a new collapsable bearing spacer, flared end
outward, to drive pinion and refit outer bearing.
91.Fit pinion oil seal.
92.Fit oil seal gasket.
93.Fit pinion oil seal, lipped side first, using general
purpose grease or, where available, a
molybdenum disulphide based grease on seal
lip, usingLRT-51-002to drift in seal.
94.Fit coupling flange and plain washer and loosely
fit a new flange nut. SecureLRT-51-003to
coupling flange, using slave fixings.
95.Alternately tighten flange nut and check drive
pinion resistance to rotation until following
figures are achieved, as applicable:
A.Assemblies re-using original pinion bearings:
17,3 to 34,5 kgf cm.
B.Assemblies with new pinion bearings: 34,5 to
46,0 kgf cm.
NOTE: Once the bearing spacer has
started to collapse the torque resistance
build-up is rapid, therefore check
frequently, using a spring balance, to ensure the
correct figures are not exceeded, otherwise a new
collapsable bearing spacer will be required.
