1–2 GENERAL INFORMATIONNUBIRA/LACETTI
1. GENERAL INSTRUCTION
This publication is designed to help you the body repair
technician with your specialized work. Vehicle bodywork
has changed a great deal over the years. As vehicles
have developed technically, vehicle bodywork has also
had to meet new requirements with design, changes to
reconcile apparently conflicting demands to name just a
few examples:
S strength and safety ; low weight
S spaciousness ; good aerodynamices
S high quality ; low price
.
The durability and ease of repair of the bodywork also
plays an important part.
.
Nowadays, the use of highly automated production
equipment makes it possible to maintain the tightest
tolerances and thus ensure a high level of quality.
.
When bodywork is damaged, the customer rightly ex-
pects it to be expertly repaired to the same quality stan-
dards.
.
At the same time, for his safety, the customer expects
you to have comprehensive knowledge of materials,
measuring and straightening methods, possible distor-
tion, optimum corrosion prevention and much more be-
sides.
.
This publication is designed to help you update your
knowledge and give you an idea of what you require to
rectify moderate or severe accident damage, for your
own safety and for the satisfaction of your customers.
2. IMPORTANT SAFETY NOTICE
2–1. BEFORE BEGINNING WORK
S Disconnect the battery to reduce the possibility of fire
caused by electrical shorts.
S Check for fuel leaks and repair as necessary.
S Remove the fuel tank and/or fuel lines if welding equip-
ment is to be used near the fuel system.
S Before welding, sanding or cutting, protect carpets and
seats with fire–proof covers.
S Follow standard safety practices when using toxic or
flammable liquids.
S Use standard safety equipment when spraying paint,
welding, cutting, sanding or grinding. Standard safety
equipment includes.
S Respirator and filter masks: Designed to filter out toxic
fumes, mist, dust or other airborn particles. Use a respi-
rator or filter mask designed to protect you from the haz-
ards of the particular job; some respirators, for example,
are designed to filter out only dust and airborn particles,
not toxic fumes.
S Safety goggles or glasses: Designed to protect your
eyes from projectiles, dust particles or splashing liquid.
S Gloves: Rubber gloves protect against corrosive chemi-
cals. Welding gloves protect against burns and abra-
sions caused by welding, sanding or grinding.
S Safety shoes: Non–slip soles protect against slipping.
Metal toe inserts protect against falling objects.
S Ear plugs: Protect eardrums from harmful noise levels.
.
2–2. DURING WORK
S Do not smoke while working near the fuel system.
S Deposit gas or solvent–soaked shop towels in an ap-
proved container.
S Brake lining contains asbestos, which can cause cancer.
Do not use an air hose to blow off brake assemblies: use
only an approved vacuum cleaner, and wear an ap-
proved filter mask or respirator.
S Always attach a safety cable when using a hydraulic ram
or a frame straightening table: do not stand in direct line
with the chains used on such equipment.

1. Remove the related parts.
S Doors.
S Weather strips, pillar trims and related parts.
S Carpet.
S Seat belt assembly
S Door switch and wiring harness.
S Fuel pipe and brake oil pipe.
S Other related parts.
Note : Pull out and straighten the damaged area to
approximately the original shape.
2. Remove the related parts.
S Damage may extend to the inner roof frame, the inner
frame door opening and the floor. Determine the extent
of the damage first, so the frame can be pulled out prop-

painting areas, seats, carpets and other parts.
S Pull out and straighten the damaged areas.
S Do not pull out more than necessary.
3. Cut and pry off the frame door opening.
S Check the damage on the frame door opening, then cut
the new frame door opening so it will overlap by
30mm(1.18in.) in the pillar, front and rear.
S Cut the damaged area with a hand saw along the bold
line as shown.
Note : Be careful not to cut the inner panel. This could
result in extensive repair.
Fig. 2
S If the damage involves part of the center pillar, cut them
as shown.
Fig. 3
S Center punch around the spot weld imprints on the
welded flange.
S Use the special spot cutter to drill holes at the spot weld
nuggets.
Note : When drilling holes be careful not to drill down to
the inner panel..
S Pry off the frame door opening panel with an air chisel,
leaving the welding flanges intact.
CAUTION : To prevent eye injury, wear goggles or
safety glasses whenever sanding, cutting, or grind-
ing.
4. Mold damaged related parts.
S Fill any holes drilled by welding.
CAUTION : To prevent eye injury and burns when
welding, wear an approved welding helmet, gloves
and safety shoes.
S Use a hammer and dolly to mold damaged areas of the
remaining inner panel and even out the welding flanges.
S Level and finish the burrs from the pried off spot welds
with disc sander.
S Sand off the paint and undercoat from both sides of the
flange to be welded.
5. Set the new frame door opening.
S Grind both sides of the welding section of the prepared
frame door opening part with a disk sander to remove
the paint and expose the steel plate.
S Clamp the new panel in place with the vise grips.
S Tack weld the clamped section for temporary installa-
tion.
CAUTION : To prevent eye injury and burns when

10–4 RUST PREVENTIONNUBIRA/LACETTI
Precautions:
.
1. Before applying an anti–rust agent, thoroughly clean
the areas to be coated with a steam cleaner, etc., and
let dry.
.
Note : Waxoyl may be applied to wet surface.
.
2. Spray an anti–rust agent sufficiently until the excess
amount oozes out when filling, the doors, etc. Wipe the
excess agent with a clean rag dampened with light oil.
.
3. Do not spray an anti–rust agent to the brake hoses,
brake wheel cylinders, brake drums, exhaust muffler
and its related parts, emission control devices in the en-
gine compartment, ball joint covers, etc. Wipe up spilled
agent at once.
.4. Heat an anti–rust agent to room temperature[36.5
C
(97.7
F)] by submerging the container in hot water
when outside temperature is below 10
C(50
F).
.
5. Ventilate when spraying an anti–rust agent since it
contains a small amount of organic solvent. Keep
sparks, flames and cigarettes away.
.
CAUTION : The remaining agent will harden in the
passages of the spray gun, making them unservice-
able.
