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,

INFORMATION JACKING
The following instructions must be carried out before
raising the vehicle off the ground.
1.Use a solid level ground surface.
2.Apply parking brake.
3.Select 'P' or 1st gear in main gearbox.
4.Select Low range in transfer gearbox.
CAUTION: To avoid damage occurring to
the under body components of the vehicle
the following jacking procedures must be
adhered to.
DO NOT POSITION JACKS OR AXLE STANDS
UNDER THE FOLLOWING COMPONENTS.
Body structure
Bumpers
Fuel lines
Brake lines
Front radius arms
Panhard rod
Steering linkage
Rear Trailing links
Fuel tank
Engine sump
Gearbox bell housing
Jack or support vehicle by axles only.Vehicle jack
The jack provided with the vehicle is only intended to
be used in an emergency, for changing a tyre. Do
NOTuse the jack for any other purpose. Refer to
Owner's Manual for vehicle jack location points and
procedure. Never work under a vehicle supported by
the vehicle jack.
Hydraulic jack
A hydraulic jack with a minimum 1500 kg, 3,300 lbs
load capacity must be used.
CAUTION: Do not commence work on the
underside of the vehicle until suitable axle
stands have been positioned under the
axle.
Raise the front of the vehicle
1.Position cup of hydraulic arm under differential
casing.
NOTE: The differential casing is not
central to the axle. Care should be taken
when raising the front road wheels off the
ground as the rear axle has less sway stiffness.

01INTRODUCTION

INFORMATION 2.Raise front road wheels to enable an axle stand
to be installed under left hand axle tube.
3.Position an axle stand under right hand axle
tube, carefully lower jack until axle sits securely
on both axle stands, remove trolley jack.
4.Before commencing work on underside of
vehicle re-check security of vehicle on stands.
5.Reverse procedure when removing vehicle from
stands.
Raise rear of vehicle
1.Position cup of hydraulic arm under differential
casing.
2.Raise vehicle to enable axle stands to be
installed under left and right hand axle tubes.
3.Lower jack until axle sits securely on axle
stands, remove trolley jack.
4.Before commencing work on underside of
vehicle re-check security of vehicle on stands.
5.Reverse procedure when removing vehicle from
stands.
HYDRAULIC VEHICLE RAMP (FOUR POST)
Use only a 'drive on' type ramp which supports vehicle
by its own road wheels. If a 'wheel-free' condition is
required, use a 'drive on' ramp incorporating a
'wheel-free' system that supports under axle casings.
Alternatively, place vehicle on a firm, flat floor and
support on axle stands.
TWO POST VEHICLE RAMPS
The manufacturer of LAND ROVER VEHICLES
DOES NOT recommend using 'Two Post' ramps
that employ four adjustable support arms. These
are NOT considered safe for Land Rover vehicles.
If vehicle is installed on a Two Post ramp
responsibility for safety of vehicle and personnel
performing service operations is in the hands of
the Service Provider.DYNAMOMETER TESTING - NON ANTI-LOCK
BRAKE VEHICLES
Viscous coupling
The front and rear axles cannot be driven
independently due to the viscous coupling. This
eliminates the need for differential lock by
progressively locking the centre differential
automatically if slip occurs at any wheel.
WARNING: DO NOT attempt to drive
individual wheels with vehicle supported
on floor jacks or stands.
Four wheel dynamometers
Provided that front and rear dynamometer 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.
If brake testing on a single axle rig is necessary it
must be carried out with propeller shaft to rear axle
removed, AND neutral selected in BOTH main
gearbox and transfer gearbox. When checking brakes,
run engine at idle speed to maintain servo vacuum.
If checking engine performance, the transfer box must
be in high range and propeller shaft to stationary axle
must be removed.

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.
