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.
