PANEL REPAIRS

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 CORROSION PROTECTION
The following information details the materials that are
applied during manufacture for corrosion protection.
Factory Treatments
The Defender is treated with the following
anti-corrosion materials in production:
A PVC-based underbody sealer material
which is sprayed onto the underfloor, wheel
arches and undersill areas.
An application of cavity wax which is
sprayed into enclosed cavities and box
sections.
A final coating of underbody wax to cover
the complete underfloor including
components but excluding brake discs,
exhaust system and propeller shafts.
A coat of protective lacquer applied to the
whole body.
A coat of protective wax applied to the
engine bay and wheel arch areas.
NOTE: Do not apply wax to engine bay of
Td5 models.
In addition to the above measures, all steel parts are
zinc-coated both sides.
Underbody Sealer
Underfloor areas and outer sill panels are treated with
a Plastisol PVC underbody sealer. This material is not
suitable for re-treatment.
When repairing areas of underbody sealer, strip the
factory-applied material back to a suitable break point,
ensuring that a clean metal surface is exposed and
that the edge of the existing material adheres soundly
to the panel.
Blanking plugs and grommets in the floor pan (except
those used for wax injection) MUST be fitted before
underbody sealer application. Heat-fusible plugs
which have been disturbed should either be refitted
with the aid of a hot air blower or replaced with rubber
grommets.
NOTE: Application of new underbody
sealer must be carried out between primer
and surfacer paint operations. Areas
where seam sealer is used should be re-treated as
necessary before application of underbody sealer.
CAUTION: Ensure that suspension units,
wheels, tyres, power unit, driveshafts,
exhaust and brakes (including all
mounting points) are shielded prior to application
of fresh underbody sealer.
Cavity Wax
Cavity wax is applied to certain box sctions The
information given on the following pages is intended
as a guide and shows the areas to be treated with
cavity wax, as well as the access holes used during
manufacture.See GENERAL INFORMATION DATA,
Sealing and corrosion protection section.
Underbody Wax
A coat of underbody wax is applied to the entire
underbody inboard of the sill vertical flanges, and
covers all moving and flexible components EXCEPT
for wheels and tyres, brakes and exhaust. The wax is
applied over paints and underbody sealers.
The underbody wax must be reinstated following all
repairs affecting floor panels.
CAUTION: Old underbody wax must be
completely removed from a zone
extending at least 200 mm (7.9 in) beyond
the area where new underbody sealer is to be
applied.
Engine Bay Wax
Reinstate protective engine bay wax disturbed during
repairs using the approved material.
Wheel Arch Wax
Reinstate protective wheel arch wax disturbed during
repairs using the approved material.
