INFORMATION SYNTHETIC RUBBER
Many '0' ring seals, flexible pipes and other similar
items which appear to be natural rubber are made of
synthetic materials called Fluoroelastomers. Under
normal operating conditions this material is safe, and
does not present a health hazard. However, if the
material is damaged by fire or excessive heat, it can
break down and produce highly corrosive Hydrofluoric
acid which can cause serious burns on contact with
skin. Should the material be in a burnt or overheated
condition handle only with seamless industrial gloves.
Decontaminate and dispose of the gloves immediately
after use.
If skin contact does occur, remove any contaminated
clothing immediately and obtain medical assistance
without delay. In the meantime, wash the affected
area with copious amounts of cold water or limewater
for fifteen to sixty minutes.
RECOMMENDED SEALANTS
A number of branded products are recommended in
this manual for use during maintenance and repair
work.
These items include:
HYLOMAR GASKET AND JOINTING COMPOUND
and
HYLOSIL RTV SILICON COMPOUND.
They should be available locally from garage
equipment suppliers. If there is any problem obtaining
supplies, contact the following company for advice
and the address of the nearest supplier.

Tel 01942 824242USED ENGINE OIL
WARNING: Prolonged and repeated
contact with engine or motor oil will result
in the removal of natural fats from the
skin, leading to dryness, irritation and dermatitis.
Used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Adequate means of skin protection and washing
facilities should be provided.
Handling precautions
1.Avoid prolonged and repeated contact with oils,
particularly used engine oils.
2.Wear protective clothing, including impervious
gloves where applicable.
3.Do not put oily rags in pockets.
4.Avoid contaminating clothes, particularly
underwear, with oil.
5.Overalls must be cleaned regularly. Discard
unwashable clothing and oil impregnated
footwear.
6.First aid treatment must be obtained immediately
for open cuts and wounds.
7.Use barrier creams, before each work period, to
help the removal of oil from the skin.
8.Wash with soap and water to ensure all oil is
removed (skin cleansers and nail brushes will
help). Preparations containing lanolin replace the
natural skin oils which have been removed.
9.Do not use gasoline, kerosene, diesel fuel,
petrol, thinners or solvents for washing the skin.
10.If skin disorders develop, obtain medical advice.
11.Where practicable, degrease components prior
to handling.
12.Where there is a risk of eye contact, eye
protection should be worn, for example, goggles
or face shields; in addition an eye wash facility
should be provided.
Disposing of used oils
Environmental protection precaution
It is illegal to pour used oil onto the ground, down
sewers or drains, or into waterways.
Dispose of used oil through authorised waste disposal
contractors. If in doubt contact your Local Authority for
advice on disposal facilities.

SPECIFICATION
The specification details and instructions set out in
this Manual apply only to a range of vehicles and not
to any one. For the specification of a particular vehicle
purchasers should consult their Dealer
The Manufacturer reserve the right to vary their
specifications with or without notice, and at such times
and in such manner as they think fit. Major as well as
minor changes may be involved in accordance with
the Manufacturer's policy of constant product
improvement.
Whilst every effort is made to ensure the accuracy of
the particulars contained in this Manual, neither the
Manufacturer or Dealer, by whom this Manual is
supplied, shall in any circumstances be held liable for
any inaccuracy or the consequences thereof.SPECIAL SERVICE TOOLS
The use of approved special service tools is
important. They are essential if service operations are
to be carried out efficiently, and safely. Where special
tools are specified,only these tools should be used
to avoid the possibility of personal injury or
damage to the components.Also the amount of time
which they save can be considerable.
Every special tool is designed with the close
co-operation of Land Rover, and no tool is put into
production which has not been tested and approved
by us. New tools are only introduced where an
operation cannot be satisfactorily carried out using
existing tools or standard equipment. The user is
therefore assured that the tool is necessary and that it
will perform accurately, efficiently and safely.
Special tools bulletins will be issued periodically giving
details of new tools as they are introduced.

INFORMATION PREPARATION
1.Before removing a component, clean it and its
surrounding areas as thoroughly as possible.
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 after
comparing it with a 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.

INFORMATION JOINTS AND JOINT FACES
1.Always use correct gaskets where they are
specified.
2.Use jointing compound only when
recommended. Otherwise fit joints dry.
3.When jointing compound is used, apply in a thin
uniform film to metal surfaces; take great care to
prevent it from entering oilways, pipes or blind
tapped holes.
4.Remove all traces of old jointing materials prior
to reassembly. Do not use a tool which could
damage joint faces.
5.Inspect joint faces for scratches or burrs and
remove with a fine file or oil stone; do not allow
removed material or dirt to enter tapped holes or
enclosed parts.
6.Blow out any pipes, channels or crevices with
compressed air, fit new 'O' rings or seals
displaced by air blast.FLEXIBLE HYDRAULIC PIPES, HOSES
1.Before removing any brake or power steering
hose, clean end fittings and area surrounding
them as thoroughly as possible.
2.Obtain appropriate plugs or caps before
detaching hose end fittings, so that ports can be
immediately covered to exclude dirt.
3.Clean hose externally and blow through with
airline. Examine carefully for cracks, separation
of plies, security of end fittings and external
damage. Reject any hose found faulty.
4.When refitting hose, ensure that no unnecessary
bends are introduced, and that hose is not
twisted before or during tightening of union nuts.
5.Containers for hydraulic fluid must be kept
absolutely clean.
6.Do not store brake fluid in an unsealed
container. It will absorb water, and fluid in this
condition would be dangerous to use due to a
lowering of its boiling point.
7.Do not allow brake fluid to be contaminated with
mineral oil, or use a container which has
previously contained mineral oil.
8.Do not re-use brake fluid bled from system.
9.Always use clean brake fluid to clean hydraulic
components.
10.Fit a cap to seal a hydraulic union and a plug to
its socket after removal to prevent ingress of dirt.
11.Absolute cleanliness must be observed with
hydraulic components at all times.
12.After any work on hydraulic systems, inspect
carefully for leaks underneath the vehicle while a
second operator applies maximum pressure to
the brakes (engine running) and operates the
steering.

INFORMATION COTTER PINS
1.Fit new cotter pins throughout when replacing
any unit.
2.Always fit cotter pins where cotter pins were
originally used. Do not substitute spring
washers: there is always a good reason for the
use of a cotter pin.
3.All cotter pins should be fitted as shown unless
otherwise stated.
NUTS
1.When tightening a slotted or castellated nut
never loosen it back to insert cotter pin or locking
wire except in those recommended cases where
this forms part of an adjustment. If difficulty is
experienced, alternative washers or nuts should
be selected, or washer thickness reduced.
2.Where self-locking nuts have been removed it is
advisable to replace them with new ones of the
same type.
NOTE: Where bearing pre-load is involved
nuts should be tightened in accordance
with special instructions.
LOCKING WIRE
1.Fit new locking wire of the correct type for all
assemblies incorporating it.
2.Arrange wire so that its tension tends to tighten
the bolt heads, or nuts, to which it is fitted.SCREW THREADS
1.Both UNF and Metric threads to ISO standards
are used. See below for thread identification.
2.Damaged threads must always be discarded.
Cleaning up threads with a die or tap impairs the
strength and closeness of fit of the threads and
is not recommended.
3.Always ensure that replacement bolts are at
least equal in strength to those replaced.
4.Do not allow oil, grease or jointing compound to
enter blind threaded holes. The hydraulic action
on screwing in the bolt or stud could split the
housing.
5.Always tighten a nut or bolt to the recommended
torque value. Damaged or corroded threads can
affect the torque reading.
6.To check or re-tighten a bolt or screw to a
specified torque value first loosen a quarter of a
turn, then re-tighten to the correct value.
7.Oil thread lightly before tightening to ensure a
free running thread, except in the case of
threads treated with sealant/lubricant, and
self-locking nuts.
UNIFIED THREAD IDENTIFICATION
1. Bolts
A circular recess is stamped in the upper surface
of the bolt head.
2. Nuts
A continuous line of circles is indented on one of
the flats of the hexagon, parallel to the axis of
the nut.
3. Studs, Brake Rods, etc.
The component is reduced to the core diameter
for a short length at its extremity.

LUBRICATION PRACTICE
Use a high quality oil of the correct viscosity range and service classification in the engine during maintenance and
when topping up. The use of oil not to the correct specification can lead to high oil and fuel consumption and
ultimately to damaged components.
Oil to the correct specification contains additives which disperse the corrosive acids formed by combustion and
prevent the formation of sludge which can block the oilways. Additional oil additives should not be used. Always
adhere to the recommended servicing intervals.
WARNING: Many liquids and other substances used in motor vehicles are poisonous. They must
not be consumed and must be kept away from open wounds. These substances, among others,
include anti-freeze windscreen washer additives, lubricants and various adhesives.
