INFORMATION INTRODUCTION
This workshop manual covers vehicles from 1995
model year onwards. Amendments and additional
pages will be issued to ensure that the manual
covers latest models. Amendments and additions
will be identified by the addition of a dated footer
at the bottom of the page.
This Workshop Manual is designed to assist skilled
technicians in the efficient repair and maintenance of
Land Rover vehicles.
Individuals who undertake their own repairs
should have some skill and training, and limit
repairs to components which could not affect the
safety of the vehicle or its passengers. Any
repairs required to safety critical items such as
steering, brakes, suspension or supplementary
restraint system should be carried out by a Land
Rover Dealer. Repairs to such items should
NEVER be attempted by untrained individuals.
WARNINGS, CAUTIONSandNOTESare given
throughout this Manual in the following form:
WARNING: Procedures which must be
followed precisely to avoid the possibility
of personal injury.
CAUTION: This calls attention to
procedures which must be followed to
avoid damage to components.
NOTE: This calls attention to methods
which make a job easier or gives helpful
information.
DIMENSIONS
The dimensions quoted are to design engineering
specification. Alternative unit equivalents, shown in
brackets following the dimensions, have been
converted from the original specification.REFERENCES
References to the left or right hand side in the manual
are made when viewing the vehicle from the rear.
With the engine and gearbox assembly removed, the
water pump end of the engine is referred to as the
front.
To reduce repetition, some operations covered in this
Manual do not include reference to testing the vehicle
after repair.
It is essential that work is inspected and tested after
completion and if necessary a road test of the vehicle
is carried out particularly where safety related items
are concerned.
REPAIRS AND REPLACEMENTS
When replacement parts are required it is essential
that Land Rover parts are used.
Attention is particularly drawn to the following points
concerning repairs and the fitting of replacement parts
and accessories: Safety features embodied in the
vehicle may be impaired if other than Land Rover
parts are fitted. In certain territories, legislation
prohibits the fitting of parts not to the vehicle
manufacturer's specification. Torque spanner values
given in the Workshop Manual must be strictly
adhered to. Locking devices, where specified, must be
fitted. If the efficiency of a locking device is impaired
during removal it must be replaced with a new one.
Certain fasteners must not be re-used. These
fasteners are specified in the Workshop Manual.
POISONOUS SUBSTANCES
Many liquids and other substances used are
poisonous and therefore must not be consumed. It is
also advisable to keep all substances away from open
wounds. These substances among others include
anti-freeze, brake fluid, fuel, windscreen washer
additives, air conditioning refrigerant, lubricants and
various adhesives.

INFORMATION ACCESSORIES AND CONVERSIONS
DO NOT FITunapproved accessories or conversions,
as they could affect the safety of the vehicle.
Land Rover will not accept liability for death, personal
injury, or damage to property which may occur as a
direct result of the fitting of non-approved conversions
to the vehicle.
WHEELS AND TYRES
WARNING: DO NOT replace the road
wheels with any type other than genuine
Land Rover wheels which are designed for
multi-purpose on and off road use and have very
important relationships with the proper operation
of the suspension system and vehicle handling.
Replacement tyres must be of the make and sizes
recommended for the vehicle, and all tyres must
be the same make, ply rating and tread pattern.
STEAM CLEANING
To prevent consequential rusting, any steam cleaning
within the engine bayMUSTbe followed by careful
re-waxing of the metallic components affected.
Particular attention must be given to the steering
column, engine water pipes, hose clips and ignition
coil clamp.
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.
All orders and enquiries from the United Kingdom
should be sent direct to V. L. Churchill. Overseas
orders should be placed with the local V. L. Churchill
distributor, where one exists. Countries where there is
no distributor may order direct from:
V. L. Churchill Limited,
PO Box 3,
Daventry, Northants,
England, NN11 4NF.
The tools recommended in this Workshop Manual are
listed in a multi-language illustrated catalogue,
obtainable from:

INFORMATION DYNAMOMETER TESTING - VEHICLES WITH
ANTI-LOCK BRAKES (ABS)
WARNING: Do not attempt to test ABS
function on a dynamometer
Four wheel dynamometers
NOTE: Before testing a vehicle on a four
wheel dynamometer disconnect the valve
relay.
See Electrical Trouble Shooting
Manual.
The ABS function will not work, the ABS warning
light will illuminate. Normal braking will be
available.
Provided that front and rear rollers are rotating at
identical speeds and that normal workshop safety
standards are applied, there is no speed restriction
during testing except any that may apply to the tyres.
Two wheel dynamometers
IMPORTANT: Use a four wheel dynamometer for
brake testing if possible.
NOTE: ABS will not function on a two
wheel dynamometer. The ABS light will
illuminate during testing. Normal braking
will be available.
If brake testing on a single rig is necessary it must be
carried out with propeller shaft to the rear axle
removed, AND neutral selected in BOTH main and
transfer boxes.
If checking engine performance, the transfer box must
be in high range and drive shaft to stationary axle
removed.
TOWING
CAUTION: The vehicle has permanent
four-wheel drive. The following towing
instructions must be adhered to:
Towing the vehicle on all four wheels with driver
operating steering and brakes.
1.Turn ignition key turn to position '1' to release
steering lock.
2.Select neutral in main gearbox and transfer
gearbox.
3.Secure tow rope, chain or cable to towing eye.
4.Release the parking brake.
CAUTION: The brake servo and power
assisted steering system will not be
functional without the engine running.
Greater pedal pressure will be required to apply
the brakes, the steering system will require
greater effort to turn the front road wheels.
The vehicle tow connection should be used only
in normal road conditions, 'snatch' recovery
should be avoided.
Suspended tow by breakdown vehicle
CAUTION: To prevent vehicle damage,
front or rear propeller shaft MUST BE
removed, dependent upon which axle is
being trailed.
1.Mark propeller shaft drive flanges at transfer
gearbox and axles with identification lines to
enable the propeller shaft to be refitted in its
original position.
2.Remove the propeller shaft fixings, remove the
shaft from the vehicle.
3.If the front axle is to be trailed turn ignition key to
position '1' to release steering lock.
CAUTION: The steering wheel and/or
linkage must be secured in a straight
ahead position. DO NOT use the steering
lock mechanism for this purpose.
