INTRODUCTION
How To Use This Manual
General
To assist in the use of this Manual, it is divided into
sections and sub-sections. The section title is given
at the top of each page and the relevant sub-section
is given at the bottom.
There is a single contents section at the front of the
Manual, which is divided by section and sub-section.
Each section is numbered from page 1.
The individual items comprising repair operations are
to be followed in the sequence in which they appear.
Items numbers in the illustration are referred to in the
text.
Adjustment and Repair operations include reference
to Service tool numbers and the associated
illustration depicts the tool in use. Adjustment and
repair operations also include reference to wear
limits, relevant data, torque figures, and specialist
information and useful assembly details. Each
adjustment or repair operation is given its Service
Repair Operation number.
WARNINGS, CAUTIONS and NOTES have the
following meanings:
WARNING: Procedures which must be followed
precisely to avoid the possibility of injury.
CAUTION: Calls attention to procedures which
must be followed to avoid damage to
components.
NOTE: Gives helpful information.
References
References to the LH or RH side given in this Manual
are made when viewing the vehicle from the rear.
With the engine and gearbox assembly removed, the
crankshaft pulley end of the engine is referred to as
the front.
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.
Dimensions
The dimensions quoted are to design engineering
specification with Service limits where applicable.
Repairs and Replacements
When replacement parts are required it is essential
that only Land Rover recommended parts are used.
Attention is particularly drawn to the following points
concerning repairs and the fitting of replacement
parts and accessories.
Safety features and corrosion prevention treatments
embodied in the vehicle may be impaired if other
than Land Rover recommended parts are fitted. In
certain territories, legislation prohibits the fitting of
parts not to the manufacturer's specification. Torque
wrench setting figures given in this Manual must be
used. Locking devices, where specified, must be
fitted. If the efficiency of a locking device is impaired
during removal it must be renewed.
Owners purchasing accessories while travelling
abroad should ensure that the accessory and its
fitted location on the car conform to legal
requirements.
The Terms of the vehicle Warranty may be
invalidated by the fitting of parts other than Land
Rover recommended parts.
All Land Rover recommended parts have the full
backing of the vehicle Warranty.
Land Rover Dealers are obliged to supply only Land
Rover recommended parts.

General Fitting Instructions
Component removal
Whenever possible, clean components and
surrounding area before removal.
lBlank off openings exposed by component
removal.
lImmediately seal fuel, oil or hydraulic lines when
apertures are exposed; use plastic caps or
plugs to prevent loss of fluid and ingress of dirt.
lClose the open ends of oilways exposed by
component removal with tapered hardwood
plugs or conspicuous plastic plugs.
lImmediately a component is removed, place it in
a suitable container; use a separate container
for each component and its associated parts.
lClean bench and provide marking materials,
labels and containers before dismantling a
component.
Dismantling
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
serious malfunction if trapped in these systems.
lBlow 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 during the process.
lUse marking ink to identify mating parts and
ensure correct reassembly. Do not use a centre
punch or scriber to mark parts, they could
initiate cracks or distortion in marked
components.
lWire together mating parts where necessary to
prevent accidental interchange (e.g. roller
bearing components).
lWire 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.
lDo not discard a part due for renewal until after
comparing it with a new part, to ensure that its
correct replacement has been obtained.Cleaning components
Always use the recommended cleaning agent or
equivalent. Ensure that adequate ventilation is
provided when volatile degreasing agents are being
used. Do not use degreasing equipment for
components containing items which could be
damaged by the use of this process.
General inspection
All components should be inspected for wear or
damage before being reassembled.
lNever inspect a component for wear or
dimensional check unless it is absolutely clean;
a slight smear of grease can conceal an
incipient failure.
lWhen a component is to be checked
dimensionally against recommended values,
use the appropriate measuring equipment
(surface plates, micrometers, dial gauges etc.).
Ensure the measuring equipment is calibrated
and in good serviceable condition.
lReject a component if its dimensions are
outside the specified tolerances, or if it appears
to be damaged.
lA part may be refitted if its critical dimension is
exactly to its tolerance limit and it appears to be
in satisfactory condition. Use 'Plastigauge' 12
Type PG-1 for checking bearing surface
clearances.

Air Conditioning Compressor
Replacement
A new compressor is supplied filled with a full charge
(X cm3) of refrigerant oil.

+ CAPACITIES, FLUIDS AND
LUBRICANTS, Capacities.A calculated quantity of
oil must be drained from the new compressor before
fitting. To calculate the quantity of oil to be drained:
1Remove the drain plug from the old
compressor.
2Invert the compressor and gravity drain the oil
into a calibrated measuring cylinder. Rotate the
compressor clutch to ensure the compressor is
completely drained.
3Note the quantity of oil drained (Y cm
3).
4Calculate the quantity of oil to be drained from
the new compressor using the following
formula:
X cm
3 — (Y cm3 + 20 cm3) = Q cm3
5Remove the drain plug from the new
compressor and drain Q cm3 of oil. Fit and
tighten the compressor drain plug.
Body Repairs
General
Body shells are of welded construction and bolted to
a chassis frame. Front and rear sections of the shell
are designed as 'energy absorbing' zones. This
means they are designed to deform progressively
when subjected to impact in order to minimise the
likelihood of injury to vehicle occupants.
It is essential that design dimensions and strength
are restored in accident rectification. It is important
that neither structural weakness nor excessive local
stiffness are introduced into the vehicle during body
repair.
Repairs usually involve a combination of operations
ranging from straightening procedures to renewal of
individual panels or panel assemblies. The repairer
will determine the repair method and this decision will
take into account a balance of economics between
labour and material costs and the availability of repair
facilities in both equipment and skills. It may also
involve considerations of the vehicles' downtime,
replacement vehicle availability and repair turn-
around time.
It is expected that a repairer will select the best and
most economic repair method possible, making use
of the facilities available. The instructions given are
intended to assist a skilled body repairer by
expanding approved procedures for panel
replacement. The objective is to restore the vehicle
to a safe running condition by carrying out a repair
which is as close as is feasible to original standard.
The results should not advertise to the experienced
eye that the vehicle has been damaged, although the
repair might not be identical in all respects to the
original factory build. Commercial bodyshop repair
facilities cannot always duplicate methods of
construction used during production.
Operations covered in this Manual do not include
reference to testing the vehicle after repair. It is
essential that work is inspected and suspension
geometry checked after completion. Where
necessary a road test of the vehicle should be carried
out, particularly where safety-related items are
concerned.
Where major units have been disconnected or
removed it is necessary to ensure that fluid levels are
checked and topped up where necessary. It is also
necessary to ensure that the repaired vehicle is in a
roadworthy condition in respect of tyre pressures,
lights, washer fluid etc.

GENERAL INFORMATION
03-27
Body repairs often involve the removal of mechanical
and electrical units and associated wiring. Where
necessary, refer to the relevant section of the
Workshop Manual for removal and refitting
instructions.
Taking into consideration the differences in body
styles, suspension systems and engine and
transmission layouts, the location of the following
components as applicable to a particular vehicle is
critical:
lFront suspension upper damper mountings on
RH and LH chassis longitudinals.
lFront suspension or sub frame mountings.
lEngine mountings on RH and LH chassis
longitudinals.
lRear suspension upper damper mountings on
RH and LH chassis longitudinals.
lRear suspension mountings or lower pivots.
Additional points which can be used to check
alignment and assembly are:
lInner holes in cross member - side - main floor.
lHoles in front bulkhead.
lHoles in rear longitudinals.
lHoles in rear lower panels.
Apertures for windscreen, rear screen, bonnet and
doors can be measured and checked using the
dimensional information provided and also by
offering up an undamaged component as a gauge.
Straightening
Whenever possible, structural members should be
cold straightened under tension. Do not attempt to
straighten with a single pull but rework the damaged
area using a series of pulls, releasing tension
between each stage and using the opportunity to
check alignment.
Body jig
Unless damage is limited to cosmetic panels, all
repair work to body members must be carried out on
a body jig, to ensure that impact damage has not
spread into more remote parts of the structure.
Mounting on a jig will also ensure that the
straightening and panel replacement procedures do
not cause further distortion.
If original dimensions cannot be satisfactorily
restored by these methods, damaged structural
members should be replaced. Damaged areas
should be cut away using a high speed saw, NOT an
oxy-acetylene torch.
As a rule, body dimensions are symmetrical about
the centre line. A good initial check for distortion is
therefore to measure diagonally and to investigate
apparent differences in dimensions.Inspection
Every accident produces individual variations in
damage. Each repair is influenced by the extent of
the damage and the facilities and equipment
available for its rectification.
Most accident damage can be visually inspected and
the approximate extent of damage assessed.
Sometimes deformation will extend beyond the
directly damaged area, and the severity of this must
be accurately established so that steps can be taken
to restore critical body components to their original
dimensions. An initial check can be carried out by
means of drop checks or, preferably, trammels.
Gauges are available which will accurately check for
body twist.
