CAUTIONS REGARDING BODY REPAIR
Because each component part of a single-unit con-
struction body makes some contribution, more or
less, to the overall strength of that body, it is neces-
sary to sufficiently understand the actual function of
any part to be repaired before attempting any repair
or welding procedure.
.
STRENGTH AND RIGIDITY
1. The suspension installation part plays an impor-
tant role, determining the wheel alignment. Wheel
misalignment is of course potentially very danger-
ous because it can lead to driving instability,
one-sided braking, abnormal tire wear, abnormal
vibration, etc.
At the time of repair, it is particularly necessary to
take measurements at the components noted
below, and to make all welds and installations
with special care.
•
Front sidemember
•
Rear floor sidemember
•
Front wheelhouse (inner)
•
Rear wheelhouse (inner) (Independent rear
suspension type)
2. Because the places where the floor panel and
sidemember parts are joined have an important
effect upon the rigidity of the entire body, welds in
these places must be done with particular care.
3. After repairs have been completed, the wheel
alignment, wheel base, tread, etc., must be care-
fully checked to be sure that there is no deviation.
.
SAFETY
1. Procedures related to the installation of any com-
ponent related to safety must be done with partic-
ular care in order to assure full maintenance of
safety.
•
Suspension installation parts
•
Fuel pipe
•
Brakes
•
Fuel tank installation parts, etc.
2. Because seat belts are directly related to driver
and passenger safety, any welds of seat belt
anchor points or reinforcements must be done
with particular care in order to maintain strength.
.
PREVENTION OF CORROSION AND OF
WATER OR DUST ENTRY
1. After any work is completed, it is important to
completely remove any welding residue, particles
or residue from cutting, and any other dirt, etc.
2. Corrosion-prevention material must without fail
be applied at the following places:
•
At any place where paint has flaked off or
peeled away.
•
At any surfaces that have been cut.
•
At the outer and inner side of every welded
place.
•
Within any semi-enclosed structure or compo-
nent (aerosol-type rust inhibitors are effective
for difficult-to-reach places).
•
At the outer and inner side of any place sub-
jected to heat.
3. Apply a coating of undercoating if the underbody
is repaired.
4. Use spot sealer if spot welds are made.
5. Repair any scratches to panels made by mold-
ings, sashes, etc.
6. Carefully apply body sealant to panel connection
joints and other fitting places.
7. Tape over any unused holes in the panel inner
side by using sealing tape.
.
VIBRATION AND NOISE
1. Prevent any decrease of tensional rigidity caused
by welding distortion.
2. Carefully apply body sealant to panel connection
joints and other fitting places.
3. Tape over any unused holes in the panel inner
side by using sealing tape.
.
CONTACT AND ALIGNMENT
1. In order to maintain the precision of openings,
make careful measurements as repairs are being
made.
2. Make contact/alignment adjustments of door
hinge, lid, and hood hinge installation parts.
