INFORMATION Straightening
Whenever possible, chassis 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 body 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 differences in
damage. Each repair is influenced by the extent of the
damage and by the facilities and equipment available
for its rectification.
Most accident damage can be visually inspected and
the approximate extent of the damage assessed.
Sometimes deformation will extend beyond the area
of direct damage, and the severity of this must be
accurately established so that steps may be taken to
restore critical body components to their original
dimensions.
An initial check of critical dimensions can be carried
out by means of drop checks or (preferably) trammels.
Gauges are available which will check accurately for
body twist. Where repairs necessitate renewal of a
critical body component it is recommended that a
body jig is used.

INFORMATION ELECTRONIC CONTROL UNITS (ECU’s)
The ECU’s fitted to Defender vehicles make it
advisable to follow suitable precautions prior to
carrying out welding repair operations. All ECU’s must
be diconnected before any welding operations take
place. Harsh conditions of heat and vibration may be
generated during these operations which could cause
damage to the units.See ELECTRICAL
PRECAUTIONS section.

BODY DIMENSIONS CHASSIS AND BODY
Chassis
The chassis on all Defender variants are of the box
section, ladder type construction, manufactured from
2 mm (14swg) steel and treated with zinc phosphate,
cathodic electro coated, followed by waxing in the rear
crossmember.
Outriggers and angled brackets welded to the chassis
support suspension and axle components and are
also used as body mounting points. A detachable box
section crossmember, located between the two
chassis longitudinals is fitted to facilitate main gearbox
and tranfer box assembly removal.Should chassis damage occur, a comprehensive
range of components are available, including body
support outriggers, cross members and radius arm
mounting brackets. ALWAYS fit genuine parts that are
fully guaranteed and to original equipment
specification, fitted with Land Rover’s BS 5135
welding standard.
Body
All body panels, with the exception of the fascia
bulkhead, are manufactured from aluminium alloy.
Galvanized steel is used for the front wheel arches to
give optimum protection. Most panels are also treated
with zinc phosphate and cathodic electro coated with
polyester surfacer, and are bolted to the welded
chassis.

BODY DIMENSIONS CHASSIS FRAME ALIGNMENT
With the vehicle assembled, a check for chassis
squareness can be made as follows:
1.Place the vehicle on a level floor.
2.Mark measuring points at approximately the
locations shown in LR4412M ensuring that the
marks are exactly opposite on each side of the
chassis frame.3.Hold a plumb line against each of the measuring
points in turn and mark the floor directly beneath
the plumb-bob.
4.Move the vehicle and measure diagonally
between the marks made on the floor, if the
chassis is square the diagonals between the
related measuring points should be within 9,50
mm.
5.Chassis frame dimensional checks can be
made, with the vehicle upper structure removed,
referring to the applicable illustration and
associated key.
