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

To

PRINCIPLES
OF
TRAMMING

All
reference
locations
shown
in

Figure

and

are

symmetrical
at
the
centerline
of
the
vehicle
For

Cross

checking

operations
are
used
to

the

relationship
between
two
locations
on

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

For
an

example
the

diagonal

measurement
calculated
on
a
horizontal

plane
between

reference

points
of

shown
in

Figure

is

atiol1

With
the

proper

scttings
the

tram
bar
will
be
on
a

piane
parallel
to
that
of

the

body
The

exception
to
this
would
be
wht
n
one
of
the

reterence
locations

is
induded

in
the

misaligned
area
then

the

parallel
plane
between
the

body
and

the
tram
bar

may

not

prevail
After

completiun
of
the

repairs
the

tram

gauge
should
be
set
at
the

specitled
dimension

to
check

the

accuracy
of
the

repair
operation

CAR

PREPARATION

Preparing
the
car
for
the

underbody
alignment
check

involves
the

following

Place

the
car
on
a
level
surface

2
The

weight
of
the
car

should
be

supported
at
the

wheel

locations

3
A

visual

damage
inspection
should
be
made

to

eliminate

unnecessary
measuring
Obviously
damaged
or

misaligned
areas

may
often
be
located

visually
BODY

TRAMMING
SEQUENCE

The

tramming
sequence
will
varv

depending
upon
the

nature
and

IOl
atiun
uf
the

misaligned
area
Priur
to

performing
any

tramming
uperation
the
h

uracy
of

refereJlce

points
to
be
used

must
be

determined
A

measurement

that

originates
from
a
reference

point

included

in
a

damaged
area

will

produce
untrue
results

and

confuse
the
evaluation

of
the

underbody
condition

Unlike

the
conventional

type
of
frame

design
the
unitized

type
of

body
construction

seldom

develops
the
condition

of

diamond
in
the
floor

pan
area
as
a
result

of
front
or

rear
end

collision
Therefore

underbody
alignment

checking
can

usually
originate
from
the

body
floor

pan

area
If

inspection
indicates
that
these

locations
have
been

disturbed

and
are
not
suitable

for

measuring
one
of

the

undamaged

suspension
locations
should
be
used

as
an

initial

reference

point
If

a
rare
situation

should
exist

where
all
of

these
lucalions

are

not
suitable
as

reference

points
repair

operations
should

begin
with
the

body
floor

pan
area
All

other

underbody
components
should
be

aligned

progressively
from
this
area
