INFORMATION BODY REPAIRS
Body shells are of riveted, bolted and welded
construction and are bolted to the chassis frame.
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 or
chassis repair.
Repairs usually involve a combination of operations
ranging from straightening procedures to renewal of
either 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 vehicles down-time,
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 with the
objective of restoring the vehicle to a safe running
condition and effecting a repair which is visually
acceptable and which, even to the experienced eye,
does not advertise the fact that it has been damaged.
This does not necessarily mean that the repaired
vehicle will be identical in all respects with original
factory build. Repair facilities cannot always duplicate
methods of construction used during production.
The panel repairs shown in this section are all based
on a 110 Station Wagon. Therefore all illustrations
and text relate only to this model. Although certain
areas of the vehicle, such as the front end, are
relevant to all models.
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 and if necessary a
road test of the vehicle is 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 when 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.
Body repairs often involve the removal of mechanical
and electrical units as well as associated wiring.
Where this is necessary use the relevant section in
this manual.
Taking into consideration the differences in body
styles, steering and suspension systems as well as
engine and suspension layouts, the location of the
following components as applicable to a particular
vehicle is critical:
Front suspension upper damper
mountings.
Front suspension or sub frame mountings.
Engine mountings on RH and LH chassis
longitudinals.
Rear suspension upper damper mountings.
Rear suspension mountings or lower
pivots.
Steering rack mountings.
Additional points which can be used to check
alignment and assembly are:
Inner holes in crossmember - side - main
floor.
Holes in valance front assembly.
Body to chassis mounting holes.
Holes in rear floor.
Holes in rear lower panels or extension
rear floor.
Fuel tank mountings.
Apertures for windscreen, backlight, bonnet and doors
can be checked by offering up an undamaged
component as a gauge and also by measuring known
dimensions.See BODY DIMENSIONS section.

SEALING AND CORROSION PROTECTION Hook Nozzle on Flexible Lance:The rigid hook
produces a highly atomised, forward-directed, fully
conical spray pattern having long range and good
dispersion characteristics. This combination has good
directional capabilities for the treatment of short,
narrow sections and may also be used for direct
spraying of inner wheel arches etc.
Position the flat area at the end of the lance at 180°to
the nozzle spray direction. This will help to guide the
spray more accurately when it is concealed in a box
section or access hole.
For general spraying move the nozzle in an arc from
side to side, to ensure full coverage.
NOTE: Keep all wax injection/application
equipment clean. Use white spirit for this
purpose immediately after wax injection
operations.
Precautions during Body Repairs and Handling
Take care when handling the vehicle in the workshop.
PVC underbody sealers, seam sealers, underbody
wax and body panels may be damaged if the vehicle
is carelessly lifted.
Always follow the correct lifting, jacking and towing
procedures as shown inGENERAL INFORMATION
DATA, Information section, paying particular
attention to the following points:
Locate trolley jack pads properly before
lifting and lower the jack fully before
withdrawal.
Use only the approved hoisting points
when overhead hoisting is required.
Locate the lifting heads of wheel-free lifts
correctly, with rubber or similar material
placed between lifting head and
underbody.Steam Cleaning and Dewaxing
Due to the high temperatures generated by steam
cleaning equipment, there is a risk that certain trim
items could be damaged and some adhesives and
corrosion prevention materials softened or liquified.
Adjust the equipment so that the nozzle temperature
does not exceed 90°C (194°F). Take care not to allow
the steam jet to dwell on one area, and keep the
nozzle at least 300mm (11.8in.) from panel surfaces.
Do NOT remove wax or lacquer from underbody or
underbonnet areas during repairs. Should it be
necessary to steam clean these areas, apply a new
coating of wax or underbody protection as soon as
possible.

SEALING AND CORROSION PROTECTION Stone Chip Resistant Paint/Primer
Re-treat all areas protected with factory-applied
anti-chip primer with suitable approved material in
repair.
Inspections during Maintenance Servicing
It is a requirement of the Land Rover Corrosion
Warranty that the vehicle body is checked for
corrosion by an authorised Land Rover dealer at least
once a year, to ensure that the factory-applied
protection remains effective.
Service Job Sheets include the following operations to
check bodywork for corrosion:
With the vehicle on a lift, carry out visual
check of underbody sealer for damage.
With the vehicle lowered, inspect exterior
paintwork for damage and body panels for
corrosion.
NOTE: Wash the vehicle and ensure that it
is free from deposits prior to inspection. It
is part of the owner’s responsibility to
ensure that the vehicle is kept free of
accumulations of mud which could accelerate the
onset of corrosion. The Dealer MUST wash the
vehicle prior to inspection of bodywork if the
customer has offered it in a dirty condition, and
pay special attention to areas where access is
difficult.
NOTE: The checks described above are
intended to be visual only. It is not
intended that the operator should remove
trim panels, finishers, rubbing strips or sound
deadening materials when checking the vehicle
for corrosion and paint damage.
With the vehicle on a lift, and using an inspection or
spot lamp, visually check for the following:
Corrosion damage and damaged
paintwork, condition of underbody sealer
on front and rear lower panels, sills and
wheel arches.
Damage to underbody sealer on main floor
and chassis members. Corrosion in areas
adjacent to suspension mountings and fuel
tank fixings.
NOTE: The presence of small blisters in
PVC underbody sealer is acceptable,
providing they do not expose bare metal.
Special attention must be paid to signs of damage
caused to panels or corrosion material by incorrect
jack positioning.
It is essential to follow the correct jacking and lifting
procedures.See GENERAL INFORMATION DATA,
Information section.
With the vehicle lowered, visually check for evidence
of damage and corrosion on all painted areas, in
particular the following:
Front edge of bonnet.
Visible flanges in engine compartment and
boot.
Lower body and door panels.
Where bodywork damage or evidence of corrosion is
found during inspection, rectify this as soon as is
practicable, both to minimise the extent of the damage
and to ensure the long term effectiveness of the
factory-applied corrosion protection treatment. Where
the cost of rectification work is the owner’s
responsibility, the Dealer must advise the owner and
endorse the relevant documentation accordingly.
Where corrosion has become evident and is
emanating from beneath a removable component
(e.g. trim panel, window glass, seat etc.), remove the
component as required to permit effective rectification.

SEALING AND CORROSION PROTECTION Underbody Protection Repairs
When body repairs are carried out, always ensure that
full sealing and corrosion protection treatments are
restored. This applies both to the damaged area, and
also to areas where protection has been indirectly
impaired as a result of accident damage or repair
operations.
Prior to straightening out or panel beating, remove all
corrosion protection material in the damaged area.
This applies in particular to panels coated with wax,
PVC underbody sealer, sound deadening pads etc.
WARNING: DO NOT use oxy-acetylene gas
equipment to remove corrosion prevention
materials. Large amounts of fumes and
gases are liberated by these materials when they
burn.
Equipment for the removal of tough anti-corrosion
sealers offers varying degrees of speed and
effectiveness. The compressed air-operated scraper
(NOT an air chisel) offers a relatively quiet mechanical
method of removal using an extremely rapid
reciprocating action. During use, direct the operating
end of the tool along the work surface.
The most common method is by the use of a hot air
blower with integral scraper.
CAUTION: High temperatures can be
generated with this equipment which may
cause fumes. Always exercise care in its
use.
Another tool, and one of the most efficient methods, is
the rapid-cutting’hot knife’. This tool uses a wide
blade and is quick and versatile, able to be used
easily in profiled sections where access is otherwise
awkward.
Use the following procedure when repairing
underbody coatings:
1.Remove existing underbody coatings.2.After panel repair, clean the affected area with a
solvent wipe, and treat bare metal with an etch
phosphate material.
3.Re-prime the affected area.DO NOT under any
circumstances apply underbody sealer
directly to bare metal surfaces.
4.Replace all heat-fusible plugs which have been
disturbed. Use rubber grommets of equivalent
size if plugs are not available, but ensure that
they are embedded in sealer.
5.Mask off all mounting faces from which
mechanical components, hoses and pipe clips,
have been removed. Underbody sealer must be
appliedbeforesuch components are refitted.
6.Brush sealer into all exposed seams.
7.Spray the affected area with an approved
service underbody sealer.
8.Remove masking from component mating faces,
and touch-in where necessary. Allow adequate
drying time before applying underbody wax.
Underbody Wax
After refitting mechanical components, including
hoses, pipes and small fixtures, mask off the brake
discs and apply a coat of approved underbody wax.
NOTE: Where repairs include the
application of finish paint coats in the
areas requiring underbody wax, paint
operations must be carried out BEFORE wax
application.
Underbonnet Wax
Where repairs have involved replacement of engine
bay panels, treat the entire engine compartment
including all components, clips and small fixtures with
an approved underbonnet lacquer or wax.
Proprietary Anti-Corrosion Treatments
The application of proprietary anti-corrosion
treatments in addition to the factory-applied treatment
could invalidate the Corrosion Warranty and should be
discouraged. This does not apply to approved,
compatible, preservative waxes which may be applied
on top of existing coatings.
