INFORMATION FUEL HANDLING PRECAUTIONS
The following information provides basic precautions
which must be observed if fuel is to be handled safely.
It also outlines the other areas of risk which must not
be ignored.
This information is issued for basic guidance only, and
in any case of doubt, appropriate inquiries should be
made of your local Fire Officer or Fire Department.
Fuel vapour is highly flammable and in confined
spaces is also very explosive and toxic and when
diluted with air becomes a readily ignitable mixture.
The vapour is heavier than air and will always fall to
the lowest level. It can readily be distributed
throughout a workshop by air current, consequently,
even a small spillage of fuel is very dangerous.
Always have a fire extinguisher containingFOAM CO
2
GAS,orPOWDERclose at hand when handling fuel,
or when dismantling fuel systems and in areas where
fuel containers are stored.
WARNING: lt is imperative that the battery
is not disconnected during fuel system
repairs as arcing at the battery terminal
could ignite fuel vapour in the atmosphere.
Always disconnect the vehicle battery BEFORE
carrying out work on the fuel system.
Whenever fuel is being handled, transferred or
stored, or when fuel systems are being dismantled
all forms of ignition must be extinguished or
removed, any lead lamps used must be flame
proof and kept clear of spillage.
No one should be permitted to repair components
associated with fuel without first having had fuel
system training.Hot fuel handling precautions
WARNING: Before commencing any
operation requiring fuel to be drained from
the fuel tank, the following procedure must
be adhered to:
1.Allow sufficient time for the fuel to cool, thus
avoiding contact with hot fuels.
2.Vent the system by removing the fuel filler cap in
a well ventilated area. Refit the filler cap until the
commencement of fuel drainage.
Fuel transfer
WARNING: Fuel must not be extracted or
drained from any vehicle while it is
standing over a pit.
The transfer of fuel from the vehicle fuel tank must be
carried out in a well ventilated area. An approved
transfer tank must be used according to the transfer
tank manufacturer's instructions and local regulations,
including attention to grounding of tanks.
Fuel tank removal
AFUEL VAPOURwarning label must be attached to
the fuel tank upon removal from the vehicle.
Fuel tank repair
Under no circumstances should a repair to any tank
be attempted.

INFORMATION PREPARATION
1.Clean components and surrounding area prior to
removal.
2.Blank off any openings exposed by component
removal using greaseproof paper and masking
tape.
3.Immediately seal fuel, oil or hydraulic lines when
separated, using plastic caps or plugs, to
prevent loss of fluid and entry of dirt.
4.Close open ends of oilways, exposed by
component removal, with tapered hardwood
plugs or readily visible plastic plugs.
5.Immediately a component is removed, place it in
a suitable container; use a separate container for
each component and its associated parts.
6.Before dismantling a component, clean it
thoroughly with a recommended cleaning agent;
check that agent is suitable for all materials of
component.
7.Clean bench and provide marking materials,
labels, containers and locking wire before
dismantling a component.
DISMANTLING
1.Observe scrupulous cleanliness when
dismantling components, particularly when
brake, fuel or hydraulic system parts are being
worked on. A particle of dirt or a cloth fragment
could cause a dangerous malfunction if trapped
in these systems.
2.Blow out all tapped holes, crevices, oilways and
fluid passages with an air line. Ensure that any
O-rings used for sealing are correctly replaced or
renewed, if disturbed.
3.Use marking ink to identify mating parts, to
ensure correct reassembly. If a centre punch or
scriber is used they may initiate cracks or
distortion of components.
4.Wire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
5.Wire labels on to all parts which are to be
renewed, and to parts requiring further
inspection before being passed for reassembly;
place these parts in separate containers from
those containing parts for rebuild.
6.Do not discard a part due for renewal until it has
been compared with the new part, to ensure that
its correct replacement has been obtained.INSPECTION-GENERAL
1.Never inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an incipient
failure.
2.When a component is to be checked
dimensionally against figures quoted for it, use
correct equipment (surface plates, micrometers,
dial gauges, etc.) in serviceable condition.
Makeshift checking equipment can be
dangerous.
3.Reject a component if its dimensions are outside
limits quoted, or if damage is apparent. A part
may, however, be refitted if its critical dimension
is exactly limit size, and is otherwise satisfactory.
4.Use 'Plastigauge' 12 Type PG-1 for checking
bearing surface clearances. Directions for its
use, and a scale giving bearing clearances in
0,0025 mm steps are provided with it.

DESCRIPTION AND OPERATION MANIFOLDS AND EXHAUST SYSTEM
Description
The exhaust systems fitted on all models with the
300Tdi engine comprise three sections; front pipe
assembly, intermediate silencer assembly, and tail
pipe and silencer assembly. All sections, including
silencers, are manufactured from luminised steel to
give the system a durable working life under all
conditions. Special clamps are provided to ensureleak proof jointing between the various sections,
which are supported by flexible rubber mountings.
Catalytic convertor
When fitted, the catalytic converter is integral with the
front pipe assembly, which also incorporates a flexible
joint. The catalyst forms part of the engine emission
control that can also include an EGR valve system
