PANEL PARTS MATCHING MARKS

A mark has been placed on each body panel to indicate the parts matching positions. When repairing parts
damaged by an accident which might affect the vehicle structure (members, pillars, etc.), more accurate and
effective repair will be possible by using these marks together with body alignment specifications.

DESCRIPTION

All dimensions indicated in the figures are actual.

When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.

When a measuring tape is used, check to be sure there is no elongation, twisting or bending.

Measurements should be taken at the center of the mounting holes.

An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.

The coordinates of the measurement points are the distances measured from the standard line of "X", "Y"
and "Z".

Handling Precautions for Plastics

NIS001AH

HANDLING PRECAUTIONS FOR PLASTICS

1.

When repairing and painting a portion of the body adjacent to plastic parts, consider their characteristics
(influence of heat and solvent) and remove them if necessary or take suitable measures to protect them.

2.

Plastic parts should be repaired and painted using methods suiting the materials

Precautions in Repairing High Strength Steel

NIS001AI

High strength steel is used for body panels in order to reduce vehicle weight.
Accordingly, precautions in repairing automotive bodies made of high strength steel are described below:

HIGH STRENGTH STEEL (HSS) USED IN NISSAN VEHICLES

SP130 is the most commonly used HSS.
SP150 HSS is used only on parts that require much more strength.

Read the Following Precautions When Repairing HSS:

1.

Additional points to consider

The repair of reinforcements (such as side members) by heat-
ing is not recommended since it may weaken the component.
When heating is unavoidable, do not heat HSS parts above
550

°

C (1,022

°

F).

Verify heating temperature with a thermometer.
(Crayon-type and other similar type thermometer are appro-
priate.)

When straightening body panels, use caution in pulling any
HSS panel. Because HSS is very strong, pulling may cause
deformation in adjacent portions of the body. In this case,
increase the number of measuring points, and carefully pull
the HSS panel.

When cutting HSS panels, avoid gas (torch) cutting if possi-
ble. Instead, use a saw to avoid weakening surrounding areas
due to heat. If gas (torch) cutting is unavoidable, allow a mini-
mum margin of 50 mm (1.97in).

When welding HSS panels, use spot welding whenever possi-
ble in order to minimize weakening surrounding areas due to
heat.
If spot welding is impossible, use M.I.G. welding. Do not use
gas (torch) welding because it is inferior in welding strength.

The spot weld on HSS panels is harder than that of an ordi-
nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a
low speed high torque drill (1,000 to 1,200 rpm) to increase
drill bit durability and facilitate the operation.

2.

Precautions in spot welding HSS
This work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:

The electrode tip diameter must be sized properly according
to the metal thickness.

The panel surfaces must fit flush to each other, leaving no
gaps.

Follow the specifications for the proper welding pitch.
