UNDERBODY
GENERAL
SERVICE
INFORMATION
Since
each
underbody
component
directly
affects
the
overall
strength
of
the
body
it
is
essential
that
proper
welding
sealing
and
rust
proofing
techniques
be
observed
during
service
operations
Whenever
the
body
is
repaired
be
sure
to
provide
the
repaired
body
parts
with
rust
proof
In
the
case
of
a
rust
proofmg
critical
underbody
component
it
is
essential
that
a
good
quality
type
air
dry
primer
such
as
corrosion
resistant
zinc
chromate
be
used
Do
not
use
combination
type
primer
surfacers
ALIGNMENT
CHECKING
PROCEDURE
Misalignment
in
the
underbody
affects
the
front
fender
door
trunk
lid
and
window
alignments
and
also
the
tail
gate
and
rear
body
opening
alignments
in
the
case
of
a
station
wagon
or
van
Underbody
misalignment
particularly
affects
the
suspension
system
thereby
causing
various
problems
that
arise
from
suspension
misalignment
It
is
essential
that
underbody
components
be
aligned
within
the
specified
dimensions
given
in
Figures
BF
13
14
and
IS
In
the
event
of
collision
damage
it
is
important
that
underbody
a1ignrnent
be
thoroughly
checked
and
if
necessary
realigned
to
the
specified
dirnensions
There
are
many
tools
that
may
be
ernployed
to
correct
collision
damage
such
as
frame
straightening
machines
external
pulling
equipment
other
standard
body
jacks

To
assist
in
checking
alignment
of
the
underbody
components
repairing
minor
underbody
damage
or
locating
replacement
parts
the
following
underbody
dimensions
and
alignment
checking
information
are
presented
PRINCIPLES
OF
TRAMMING
All
reference
locations
shown
in
Figure
BF
13
14
and
15
are
symmetrical
at
the
centerline
of
the
vehicle
For
example
wheo
performing
a
crosHheck
of
the
body
floor
panel
dimensions
Figures
BF
I3
14
and
IS
the
diagonal
measurement
should
be
the
same
in
boflii
directions
Cross
checking
operations
are
used
to
deter
mine
the
relationship
between
two
locations
on
the
underbody
To
measure
the
distance
between
any
two
reference
points
on
the
underbody
accurately
two
specifications
are
required
I
The
horizontal
dimension
between
the
two
points
to
be
measured
2
The
vertical
dimension
from
the
datum
line
to
the
points
to
be
measured
For
an
example
the
diagonal
measurement
calculated
on
a
horizontal
plane
between
reference
points
of
dimension
line
L
shown
in
Figure
BF
I3
is
631
3
mm
24
8
in
The
specifications
from
the
datum
line
have
a
vertical
height
difference
of
11
6
mm
0

between
the
forward

The
