PANEL REPAIRS
BODY REPAIRS 77-2-1
PANEL REPAIRS
General
Body shells are of monocoque construction. 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.
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.
Body components
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.
lFront suspension or sub frame mountings.
lRear suspension upper damper mountings.
lRear suspension mountings or lower pivots.
Additional points which can be used to check alignment and assembly are:
lInner holes in crossmember - side - main floor.
lHoles in front longitudinals.
lHoles in side members.
lHoles in rear longitudinals.
lHoles in rear lower panels or extension rear floor.
Apertures for windscreen, backlight, 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.

CORROSION PREVENTION AND SEALING
CORROSION PREVENTION 77-4-5
Corrosion Prevention
The following information details Corrosion Prevention treatments.
Factory treatments
During production, vehicle bodies are treated with the following anti-corrosion materials:
lAn application of cavity wax which is sprayed into the sill panels and the lower areas of the door panels.
lA PVC-based underbody sealer which is sprayed onto the underside of the main floor and sills, the exterior of
the safe well and the forward face of the lower dash crossmember.
lA coating of underbody wax which is applied to the entire underbody inboard of the sill vertical flanges, and
covers all moving and flexible components EXCEPT for wheels, tyres, brakes and exhaust.
lA coat of protective wax applied to the engine bay area.
Whenever body repairs are carried out, ensure the anti-corrosion materials in the affected area are repaired or
renewed as necessary using the approved materials.
Cavity wax injection
Areas treated with cavity wax are shown in the following Figures. After repairs, always re-treat these areas with an
approved cavity wax. In addition, treat all interior surfaces which have been disturbed during repairs whether they
have been treated in production or not. This includes all box members, cavities and door interiors. It is permissible to
drill extra holes for access where necessary, provided these are not positioned in load-bearing members. Ensure that
such holes are treated with a suitable zinc rich primer, brushed with wax and then sealed with a rubber grommet.
Before wax injection, ensure that the cavity to be treated is free from any contamination or foreign matter. Where
necessary, clear out any debris using compressed air.
Ensure that cavity wax is applied AFTER the final paint process and BEFORE refitting any trim components.
During application, ensure that the wax covers all flange and seam areas and that it is adequately applied to all
repaired areas of both new and existing panels.
It should be noted that new panel assemblies and complete body shells are supplied without wax injection treatment.
Ensure that such treatment is carried out after repairs.
Effective cavity wax protection is vital. Always observe the following points:
lComplete all paint refinish operations before wax application.
lClean body panel areas and blow-clean cavities if necessary, before treatment.
lMaintain a temperature of 18°C during application and drying.
lCheck the spray pattern of injection equipment.
lMask off all areas not to be wax coated and which could be contaminated by wax overspray.
lRemove body fixings, such as seat belt retractors, if contamination is at all likely.
lMove door glasses to fully closed position before treating door interiors.
lTreat body areas normally covered by trim before refitting items.
lCheck that body and door drain holes are clear after the protective wax has dried.
lKeep all equipment clean, especially wax injection nozzles.

CORROSION PREVENTION AND SEALING
SEALING 77-4-9
Inspections during maintenance servicing
It is a requirement of the 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:
lWith the vehicle on a lift, carry out visual check of underbody sealer for damage.
lWith the vehicle lowered, inspect exterior paintwork for damage and body panels for corrosion.
The vehicle must be washed and 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. It will be necessary
for the vehicle to be washed by the Dealer prior to inspection of bodywork if the customer has offered the vehicle in
a dirty condition. Particular attention should be paid to areas where access is difficult.
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:
lCorrosion damage and damaged paintwork, condition of underbody sealer on front and rear lower panels, sills
and wheel arches.
lDamage to underbody sealer. Corrosion in areas adjacent to suspension mountings and fuel tank fixings.
The presence of small blisters in underbody sealer is acceptable, providing they do not expose bare metal.
Pay special attention to signs of damage caused to panels or corrosion protection material by incorrect jack
positioning.
caut : It is essential to follow the correct jacking and lifting procedures.
With the vehicle lowered, visually check for evidence of damage and corrosion on all visible painted areas, in
particular the following:
lFront edge of bonnet.
lVisible flanges in engine compartment.
lLower body and door panels.
Rectify any bodywork damage or evidence of corrosion found during inspection 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
prevention 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.
