PRECAUTIONS IN HANDLING REFRIGERANT LINES
• All metal tubing lines should be free of kinks, be-
cause of the restriction that kinks will offer to the
flow of refrigerant. The refrigeration capacity of the
entire system can be greatly reduced by a single
kink.
• The flexible hose lines should never be bent to a
radius of less than 10 times the diameter of the hose.
• The flexible hose lines should never be allowed to
come within a distance of 2-1/2" of the exhaust
manifold.
• Flexible hose lines should be inspected at least once
a year for leaks or brittleness. If found brittle or
leaking they should be replaced with new lines.
• Use only sealed lines from parts stock.
• When disconnecting any fitting in the refrigeration
system, the system must first be discharged of all
refrigerant. However, proceed very cautiously re-
gardless of gauge readings. Open very slowly, keep-
ing face and hands away so that no injury can occur
if there happens to be liquid refrigerant in the line.
If pressure is noticed when fitting is loosened, allow
it to bleed off very slowly.
CAUTION: Always wear safety goggles when
opening refrigerant lines.
• In the event any line is opened to atmosphere, it
should be immediately capped to prevent entrance
of moisture and dirt.
• The use of the proper wrenches when making con-
nections on "O" ring fittings is important. The use
of improper wrenches may damage the connection.
The opposing fitting should always be backed up with
a wrench to prevent distortion of connecting lines or
components. When connecting the flexible hose con-
nections it is important that the swagged fitting and
the flare nut, as well as the coupling to which it is
attached, be held at the same time using three dif-
ferent wrenches to prevent turning the fitting and
damaging the ground seat.
• "O" rings and seats must be in perfect condition.
The slightest burr or piece of dirt may cause a leak.
• Sealing beads on hose clamp connections must be
free of nicks and scratches to assure a perfect seal.
MAINTAINING CHEMICAL STABILITY IN THE
REFRIGERATION SYSTEM
The metal internal parts of the Chevrolet refrigeration
system and the refrigerant and oil contained in the sys-
tem are designed to remain in a state of chemical
stability as long as pure R-12 and uncontaminated re-
frigeration oil is used in the system.
However, when abnormal amounts of foreign materials,
such as dirt, air or moisture are allowed to enter the
system, the chemical stability may be upset. When ac-
celerated by heat, these contaminates may form acids
Fig.
40-^-System Contaminants
and sludge and eventually cause the breakdown of com-
ponents within, the system. In addition, contaminates may
affect the temperature-pressure relationship of R-12,
resulting in improper operating temperature and pres-
sures and decreased efficiency of the system.
The following general practices should be observed to
insure chemical stability in the system.
• Whenever it becomes necessary to disconnect a
refrigerant or gauge line, it should be immediately
capped. Capping the tubing will also prevent dirt and
foreign matter from entering.
• Tools should be kept clean and dry. This also in-
cludes the gauge set and replacement parts.
• When adding oil, the container should be exception-
ally clean and dry due to the fact that the refrigera-
tion oil in the container is as moisture-free as it is
possible to make it. Therefore, it will quickly absorb
any moisture with which it comes in contact. For
. this same reason the oil container should not be
opened until ready for use and then it should be
capped immediately after use.
• When it is necessary to open a system, have every-
thing you will need ready and handy so that as little

GENERAL DESCRIPTION
.
A
structural network
of
steel forms the backbone
of
the
Corvette body. When combined with
the
fiber-glass
re-
inforced plastic body panels,
the
steel-plastic marriage
results
in a
body with increased torsional rigidity
and
greater beaming strength.
Convertible models continue with two roof styles:
the
folding
top
and the removable hardtop. In operation, both
tops function similar to those
of
previous models. Either
top
is
standard and both
are
optional
as
determined by
the top selected
as
base equipment.

GENERAL INSTRUCTIONS
The following gives information necessary for repair
of collision damage and performance of general main-
tenance on both the 19437 and 19467 Corvette bodies.
Included here is information dealing with availability of
repair panels, general installation procedures for in-
staUing panels and repairing damage to the body.
Repair of fiber glass reinforced plastic bodies is a
relatively easy matter if a few simple precautions are
observed.
In cases where welding must be done on steel parts
which are stiU installed on body, do not allow flame or

Removal
1.
With car on suitable hoist or jack, (support vehicle
by frame so control arms may swing free) remove
wheel and tire assembly, stabilizer bar and shock
absorber. Loosen the lower ball joint to steering
knuckle nut, and the' two lower control arm cross
shaft bushing bolts.
2.
Place Tool J-6874-1 across top of sixth coil (ap-
prox.),
then loosely secure Tool J-6874-2 to the up-
per shoe, with attaching capscrews and lock washers.
The upper shoe "V" notch and lower shoe raised land
should contact spring.
3.
Insert Tool J-6874 up through center of spring and
attach to upper and lower shoe assembly.
4.
Position spacers under shock absorber mounting hole
and against bottom of lower control arm. Install
special bearing washer and Tool J-6874-5. Locate
bearing against spacer and large washer against
bearing. Feed screw up through large washer bear-
ing and spacer and thread into Tool J-6874 and
tighten snugly (fig. 22).
5.
Center shoe assembly on spring and tighten screw
until a very slight compression is placed on spring
(fig. '22). Then firmly tighten down the two cap-
screws securing the upper and lower shoes to lock
these shoes to spring.
6. Turn head of screw until spring is compressed just
enough to clear the spring tower, then remove the
lower ball joint to steering knuckle nut (fig. 22).
NOTE: It may be necessary to assist the
spring out of the spring tower with a pry bar or
a similar tool.
7.
Disconnect the lower ball joint from the steering
knuckle and lower the control arm with the com-
pressed spring. Immediately release compression
on spring by backing off long screw. Release spring
and tool and withdraw spring.
CAUTION: The spring force under compres-
sion is very large. Exercise every safety pre-
caution when performing this operation to see
that individuals and materials subject to damage
are removed from the path of the spring when
the control arm is being lowered. Also, the
compressed spring
be relaxed immedi-
ately after lowering the control arm to reduce
the time of exposure to the large compressive
force.
Installation
1.
Position spring with closely coiled end up. Place
Tool J-6874-1 across the top of the sixth coil (ap-
prox.) then loosely secure Tool J-6874-2 to the
upper shoe with attaching capscrews and lock wash-
ers.
The upper shoe MV" notch and lower shoe
raised land should contact spring.
2.
Insert Tool J-6874 up through center of spring and
attach to upper and lower shoe assembly with bolt
and nut.
3.
Set spring in its seat on the lower control arm.
4.
Position spacers centrally under shock absorber
mounting hole and against bottom of lower control
arm. Install bearing, large washer and Tool
J-6874-5.
Locate bearing against spacer and large
washer against bearing. Feed the screw up through
large washer, bearing and spacer and thread into
yoke rod. Tighten snugly, but do not start to draw
down yet
5.
Center the shoe assembly on the spring and tighten
the lag screw until a very slight compression is
placed on spring, then firmly tighten down the two
capscrews securing the upper and lower shoes. This
will lock the shoes to the coil spring.
6. Turn head of screw until spring is compressed just
enough to clear the spring tower.
NOTE: It may be necessary to assist the
spring into the spring tower with a pry bar or
similar tool.
7.
Immediately install the lower ball joint into steering
knuckle and secure in place with attaching nut.
8. Release compression on spring and at the same time
use a drift to guide the coil spring into its proper
seat. End of coils must be 3/8" from coil stops in
spring seat.
9. Tighten the lower ball joint to steering knuckle nut
and lock with cotter key.
10.
Install shock absorber and stabilizer bar.
11.
Install wheel, tire and drum assembly.
12.
Remove car from hoist or jack stands.
13.
Tighten the two lower control cross shaft bushing
bolts to 45-55 lbs. ft. torque.
NOTE: If a suitable adjustable jack-stand is
