To
prevent damage causedbystones, thelower outerbodypanels (fender, door,etc.)have anadditional layer
of Stone Guard CoatovertheEDprimer coating. Thus,when replacing orrepairing thesepanels, apply
undercoat tothe same portions asbefore. Useacoat which isrust preventive, durable,shockresistant andhas
a long shelf life.

• Alldimensions indicatedinfigures areactual ones.
• When usingatracking gauge,adjustbothpointers toequal length. Thencheck thepointers andgauge

• When ameasuring tapeisused, check tobe sure there isno elongation, twistingorbending.
• Measurements shouldbetaken atthe center ofthe mounting holes.
• Anasterisk

•
The electrode tipdiameter mustbereformed
properly according tothe panels thickness.
•
The spot ungget onHSS panel isharder than
that ofan ordinary steelpanel.
Therefore, forspot cutting HSSpanel, ahigh
torque drillofalow speed (1,000 to1,200
rpm) maybeused tomaintain itsdurability
and facilitate theoperation.
• HSS panels withatensile strength of785 to981 N/mm

114to142 klb/sq in),
used asreinforcement inthe door guard barand inthe bumper, istoo high intensile strength touse
for general repairs.Whenthesepanels aredamaged, theouter panels alsosustain consequential
damage; therefore, thesepanels arenever remedied withoutreplacing thedoor assembly orbumper
assembly.
2. Precautions inspot welding
This work should beperformed understandard workconditions. However,workcontrol mustbeexercised

recommended

• The repair ofreinforcements (suchasside
members) byheating isnot recommended
since itinvolves theriskoflowering strength.
When heating isunavoidable, donot heat
such parts attemperatures above550°C (1,

022°F)

Heating temperature shouldbeverified with
a thermometer. (Acrayon-type andother
thermometer areavailable.)
• When straightening bodypanels, usecaution
in pulling anyHSS panel. Because itis very
strong, thismay cause deformation inadja-
cent portions ofthe body. Inthis case,
increase thenumber ofmeasuring points,
and carefully pulltheHSS panel.
Special
consideration forHSS must begiven tothe following points:
1 .Additional pointstoconsider
• Incutting HSSpanel, avoidgascutting if
possible. Instead,useanairsaw orahand
cutter toavoid decreasing thestrength of
surrounding portionsduetothe influence of
heat. Incase gascutting isinevitable, a
minimum allowance of50 mm (1.97 in)
must begiven.
