GENERAL NOTES ON BODY REPAIRING
When undertaking any
body
repair operation,
it
is
advisable
to
follow
astandard technique
as
detailed in the
following
notes.
If
the
body
shows deep
distortions
resulting
from
acollision
or
an
accident, the damaged parts must
be
replaced
with
new ones;
this
will
ultimately
save
money and
will
ensure
that
both
car's
styling
and structure
are
restored.
All
body
component
parts
are
available
as
spares and
are
also
entered in the spare parts catalogue
of
the model concerned.
•For replacing, the damaged parts must be cut
off
along the
joining
lines, suitably designed
for
this purpose,
with
the aid
of
tin
snips,
trimming
shears, hack saws
or
simi lar means
suitable
for
straight
cutting
the sheet metal
without
warping
it.
To
drill
through
the
spot welds,
use
drills
slightly larger in
diameter than spots
(drill
0.0.
from
3
to
4mmI
so
as
to
avoid stressing the parts
to
be
left
in
while
attempting
to
tear
off
spot welds.
To
separate arc welded parts,
use
chisel
to
chip
off
the beads
or
grind
the beads
down
in
order
to
prevent
putting
structural components under undue strains;
with
the chisel,
part
then sheet metal panels
from
each other.
•
Trim
and smooth
out
the edges
of
cut
off
panels.
Properly
fill
all holes,
left
after
drilling
the
spot welds,
by
welding
with
a
filler
rod. Carefully
trim
with
a
file
the
edges
to
be
joined together
both
of
body
sheet metal and replacement
panel and get rid
of
any sign
of
finish material
from
areas
to
be
welded.
•
To
prevent the spot welds
from
oxidizing,
especially those
particularly
exposed
to
atmospheric agents, coat the affected
parts
with
asuitable rust
inhibiting
compound
before
welding.
WARNING
-On models featuring A.C. generators, disconnect
terminals before welding
to
prevent damaging the diodes.
•Keep parts properly positioned
by
clamping them in place;
where this
is
not
practicable, make some spot welds
to
hold
the parts together.
3
GENERAL NOTES ON BODY REPAIRING
•
After
ensuring
that
all parts are in
proper
alignment, weld the components together
following,
as
to
spot weld diameter and spacing
or
arc welding beads, the
factory's
technique.
Remove welding
scales
by
peening and smooth
out
any roughness.
Slight
dents
or
bulges in
body
panels
can
be
corrected
by
hammering.
•
If
imperfections
persist, smooth
out
the affected
areas
with
a
body
grinder,
taking care
not
to
reduce excessively
the thickness
of
sheet metal, especially
along the
edges
or
the stiffening ribs.
If
the surfaces
are
not
perfectly
flush,
fill
low
spots
with
body
solder.
•
If
suitable templates are
not
available, doors and lids can
be
checked
for
proper
fit
with
their
openings
by
means either
of
new replacement parts
or
doors and lids themselves
of
the car being
repaired provided
that
not
warped
out
of
shape.
•Should
an
opening require
to
be
brcught
back
into
alignment
with
the
use
of
hydraulically·controlled
straight-
ening jacks, special care must
be
taken
to
avoid stressing
out
of
line
other
parts
of
body
that
previously checked
within
alignment
limits.
Performing the repair operations in
workmanlike
manner,
as
aguarantee
that
the structural strength
has
not
been impaired, rests
on
the operator's skill and responsibility.
CAUTION
-When accomplishing repair works, always
use
suitable
clothing
and observe all safety
precautions
as
prescribed
by
safety regulations.
4
BODY ALIGNMENT CHECKING BENCH
GENERAL
If
the
body
shows sign
of
warping
it
must undergo abench check.
To
this purpose, remove the engine
compartment
lid and all mechanical
units:
engine,
clutch,
gearbox,
rear axle,
front
and rear suspension, steering gear, radiator, exhaust pipe.
An overhead crane
is
the most convenient means
for
hoisting the
body
and placing
it
over the bench.
If
the
body
does
not
fit
or
fits
improperly
to
the alignment checking jigs,
it
must
be
brought
back
into
line
or
the
distorted
components replaced
with
new ones.
As
an
aid
for
the
bodyman,
further
details
on
this
matter
are given in the
following
pages
together
with
the procedures
for
carrying
out
the checks and
some
repairs.

BODY ALIGNMENT CHECKING BENCH
ALIGNMENT CHECKING
Usually, the procedure
for
checking the
body
alignment starts
with
the checking
of
front
suspension
attachments
first,
then
with
that
of
rear suspension attachments. However, this sequence may
not
be
followed
strictly
as
it
depends much on the
type
of
work
to
be
performed.
For
example,
if
the rear end
of
the
body
has
been repaired, the
front
end
will
be
set
first
and then the check carried
out
on the rear
end; conversely,
if
the
front
is the end affected
by
repairs
or
any
doubt
exists on the alignment
of front
suspension attachments, the
order
of
operations shall
be
reversed.
If
the repairs have been
skillfully
carried
out,
all dowels should match freely the respective holes or, at
the most,
after
aslight pressure
is
applied
by
hand, Never deliver blows
to
the dowels
or
apply pressure
on them
other
than manually. The diameter
of
each dowel
is
much smaller than the bore
of
the
corresponding hole in the jig; this clearance corresponds
to
the
maximum
tolerance allowed
for
the
positioning
of
the
hole.
The
illustration
below
shows the dowels
as
fitted
for
checking the alignment
of
the
1750
Saloon
body.
A.8.0062

The dowels
as
fitted
are the
same
on
both
sides and symmetrical
about
the longitu-
dinal centreline.

For checking the steering
box
and the
relay crank attachments,
use
the
extension
gauge, special tool P.N. A.8.0056, and,
acting
from
inside the engine com·
partment,
proceed
as
follows:
•
Hold
the extension
gauge
in such a
way
that
the
wing
nut
A
is
pointing
upward
and make sure
that
the end
flanges bearing the markings
Sand
D
are positioned respectively at the
left
and
at
the
right
skirt.
•Slacken the
wingnut
Aand extend the
gauge
so
that
the dowels on the end
flanges can be inserted in the holes in
the skirts.
•Check
that
the reference marks on the
two
gauge tubes
are
aligned perfectly
or
within
a
maximum
tolerance
of
!0.5 mm.
