REMOVAL OF ADJACENT
PARTS
When removing adjacent parts
by avoid accidental marring,
etc., wrapping the tools used
and surrounding body parts in
protective tape.
NOTE:
1) Take particular care not
to damage any screw or
clip holes.
2) If you do scratch a
painted surface, retouch
immediatly after. Even a
small scratch will result
in rust and corrosion.
Proper and Efficient Work Procedures
REMOVAL
REMOVAL. OF ADJACENT COMPONENTS
When removing adjacent components, apply
protective tape to the surrounding body and
your tools to prevent damage.
CAUTION:
1. Be especially careful not to damage
screw or clip holes.
2. If the paint is accidently scratched, ap-
ply touch−up paint immediately. Even
the slightest scratch may result in cor-
rosion or appearance of rust.
NO. OF SPOT WELDS
Make a note of the
number of spot welds
for later reference.
NOTE: The number
of spot welds may
vary depending on
the vehicle.
PRE−REMOVAL MEASURING
Before removal or cutting opera-
tions, take measurements in ac-
cordance with the dimension dia-
gram. Always use a puller to
straighten a damaged body or
frame.
CUTTING AREA
Always cut in a straight
line and avoid reinforced
areas.
PRECAUTIONS FOR DRILLING OR
CUTTING
Check behind any area to be drilled or
cut to insure that there are no hoses,
wires, etc., that may be damaged.

INSTALLATION
WELDING PRECAUTIONS
1. The number of welding spots
should be as follows.
Spot weld: 1.3 x No. of
manufacturer’s spots.
Plug weld: More than No. of
manufacturer’s plugs.
POST−WELDING REFINISH-
ING
1. Always check the welded
spots to insure they are
secure.
2. When smoothing out the
weld spots with a disc
grinder, be careful not to
grind off too much as this
would weaken the weld.
PRE−WELDING MEASUREMENTS
Always take measurements before
installing underbody or engine com-
ponents to insure correct assembly.
After installation, confirm proper fit.

When welding panels with a
combined thickness of over 3
mm (0.12 in.), use a MIG
(Metal Inert Gas) welder for
plug welding.
NOTE: Spot welding will
not provide sufficient dura-
bility for panels over 3 mm
(0.12 in.) thick.
For treatment
against corrosion,
remove the paint
from the portion of
the new part and
body to be welded,
and apply weld−
through primer.

MAKING HOLES FOR PLUG WELDING
For areas where a spot welder cannot
he used, use a puncher or drill to make
holes for plug welding.
