AIR CONDITIONING 1B-17
If prescribed vacuum cannot be reached, close
vacuum control valve, shut off pump and look
for a leak at connections or pump.
3. When gauge reaches prescribed vacuum, the
system is fully evacuated. Close the high-side
gauge set valve and turn off the vacuum pump.
4. Watch low-side gauge to be sure vacuum holds
for five (5) minutes. If vacuum is held, discon-
nect vacuum hose at gauge set and then proceed
to charging.
5. If vacuum does not hold for five (5) minutes,
charge system with
420ml(1/2 pound) Refriger-
ant-12 and leak check. Discharge system again
and repair leak as necessary. Repeat evacuation
procedure.
To Begin Charging of the NC System
1. Start engine and set A/C mode control button on
"OFF. "
2. With the Refrigerant-12 drum or 420ml (14
ounce)
can(s) inverted, open R-12 source
valve(s) and allow 480ml (1 pound) or one
420m1 (14 02.) can of liquid R-12 to flow into
system through low-side service fitting.
3. As soon as 480ml (1 lb.) or one 420ml (14 oz.)
can of R-12 has been added to system, immedi-
ately engage the compressor by setting the
A/C
control button to NORM and blower speed on
HI, to draw in the remainder of the R-12 charge.
See specifications for total R-12 charge. The
charging operation can be sped up by using
a large volume fan to pass air over the con-
denser. If condenser temperature is maintained
below charging cylinder temperature,
Refriger-
ant-12 will enter the system more rapidly.
4. Turn off
R-12 source valve and run engine for
30 seconds to clear lines and gauges.
5. With the engine running, remove the charging
low-side hose adapter from the accumulator ser-
vice fitting. Unscrew rapidly to avoid excess
R-12 escape from system.

MAJOR REPAIR PROCEDURES
Service repair procedures to the
Compressor Shaft Seal,
Pressure Relief Valve
or disassembly
of the Internal Compressor
Cylinder and Shaft Assembly are considered
"MAJOR" SINCE THE REFRIGERATION
SYSTEM MUST BE DISCHARGED,
EVACUATED AND RECHARGED to complete
service and/or because major internal
operating and sealing components of the
compressor are being disassembled and
serviced.
When replacing the shaft seal assembly or
pressure relief valve, even if the compressor remains on
the vehicle during the operation, it will be necessary to
discharge the system of refrigerant (see Section
1B).
Other than clutch repair procedures, the same holds
true for any disassembly of the compressor.
If the compressor shell, front head or cylinder
and shaft assembly are to be serviced or replaced, the
oil in the compressor must be drained, measured and
replaced (see Section
1B) to determine addition of
proper oil quantity to new assembly.
A clean workbench, preferably covered with a
sheet of clean paper, orderliness in the work area and
a place for all parts being removed and replaced is of
great importance, as is the use of the proper, clean
service tools.
NOTICE: Any attempt to use make-shift or
inadequate equipment may result in damage
and/or improper compressor operation.
All parts required for servicing the internal
compressor are protected by a preservation process and
packaged in a manner which will eliminate the
necessity of cleaning, washing or flushing of the parts.
The parts can be used in the internal assembly just as
they are removed from the service package.
Seals and
protective packaging should be left in tact un
ti1 just
prior to installation.
SI-IAFT SEAL
Fig. 35 thru 40
Shaft Seal Design
The shaft seal is a one piece design.
Seal Leak Detection
A shaft seal should not be changed because of an
oil-line on the hood insulator. The Seal is designed to
seep some oil for lubrication purposes. Only change a
Shaft Seal when a leak is detected by evidence of oil
sprayed in large amounts and then only after actual
refrigerant leakage is found by using an approved leak
Detector such as J-29547 or equivalent.
Should an R-4 compressor shaft seal ever have to
be replaced, the accumulator in this R-4 system must
also be removed from the vehicle. The oil in the
accumulator then must be drained, measured and
replaced according to the directions in Section
1B to
determine oil loss.
On-Car
Remove
or Disconnect
1. Discharge A/C system
2. Loosen and reposition compressor in mounting
brackets
3. Clutch Plate and Hub assembly
4. Shaft seal seat retainer ring, using Snap Ring
Pliers J-5403-A
5. Thoroughly clean inside of compressor neck area
and O-ring groove surrounding the shaft, the
exposed portion of the seal seat and the shaft
itself. Any dirt or foreign material getting into
compressor may cause damage.
6. Remove Lip Seal:
e Fully engage the knurled tangs of Seal
Remover-Installer J-23 128-A into the
recessed portion of the Seal by turning the
handle clockwise. Remove the Seal from the
compressor with a rotary-pulling motion.
Discard the Seal. The handle must be
hand-tightened securely. Do not use a
wrench or pliers.
7. Discard the seal seat O-ring from the compressor
neck using 0-Ring Remover J-9553-01.
8. Recheck the shaft and inside of the compressor
neck and O-ring groove for dirt or foreign
material and be sure these areas are perfectly
clean before installing new parts.
Inspection
Seals should not be reused. Always use a new
specification service seal kit on rebuild. Care should be
taken to prevent damage to the lip of the one piece seal.
Make sure that the Seal Seat and Seal Lip are free of
lint and dirt that could damage the seal surface or
prevent sealing.
On-Car
Install
or Connect
1. Dip
the new seal O-ring in clean 525 viscosity
refrigerant oil and assemble onto 0-Ring
Installer J-33011.
2. Insert
the 0-Ring Installer
5-3301 1 completely
down into the compressor neck until the Installer
"bottoms." Lower the moveable slide of the
0-Ring Installer to release the 0-Ring into the
seal seat O-ring lower groove. (The compressor
neck top groove is for the shaft seal retainer ring.)
Rotate the Installer to seat the O-ring and remove
the Installer.
3. Prepare Lip Seal:
Assemble seal to Seal Installer J-23128-A,
by turning handle clockwise, and then push
Seal Protector J-34614, into seal lip. The
stamped steel case side of the lip seal must
be engaged with knurled tangs of installer so
that flared-out side of lip seal is facing and
installed towards the compressor.
4. Install Lip Seal:

CHASSIS SHEET METAL 2@-7
3. During the above flash time period (1 to 10 min-
utes), apply appropriate "conventional" interior acrylic lacquer color as required and allow
painted part to dry for
4 to 5 hours before install-
ing on car.
RlGlD OW HARD ABS PMS"TIC PARTS
Rigid or hard ABS plastic requires no primer.
"Conventional" interior acrylic lacquers adhere satis-
factorily to hard ABS plastics.
Procedure
1. Wash part thoroughly with a cleaning solvent
(Acrylic-Clean, Pre-Kleano, Prep-Sol or equiv-
alent) to remove any dirt or grease.
2. Apply appropriate "conventional" interior
acrylic lacquer color. Apply only sufficient
color for proper hiding to avoid washout of
"grain" effect.
3. Allow to dry and then install part.
VINYL AND FLEXIBLE (Son) ABS
PLASTIC PARTS
The outer cover or skin material of "flexible"
instrument panel cover (pad) assemblies is made of an
ABSIPVC plastic blend. The same is true of many
"padded" door trim assemblies. The soft cushion pad-
ding under the I.P. skin is urethane foam plastic. The
most widely used
"flexible" vinyls (poly vinyl chlo-
ride)
are coated fabrics, such as used in seat trim,
some door trim assemblies, molded headlining panels
and sun visors. Most head rests are "flexible" vinyls.
Examples of "hard vinyls are: door and front seat
back assist handles and coat hooks.
The paint system of vinyl and flexible ABS
plastic involves the use of interior "vinyl" color and a
clear vinyl top coat.
Procedure
1. Wash part thoroughly with a vinyl cleaning and
preparation solvent ("Vinyl Press"
- Ditzler,
"Vinyl Prep Conditioner"
- Detroit Autobody
or equivalent) to remove greasy film or silicone.
Wipe off cleaner while still wet with clean,
lint-
free cloth.
2. Immediately after wiping face dry, apply inte-
rior "vinyl" color in wet coats allowing suffi-
cient flash time between coats (see label
directions on can). Use proper "vinyl" color as
designated by interior trim combinations. Apply
only sufficient color for proper hiding to avoid
washout of "grain" effect. No primer or
primer-
sealer is required.
3. Before the final vinyl color coat has dried, apply
two coats of clear vinyl top coat spray (instru-
ment panels will require the "nonglare" clear top
coat). Do not allow the first spray coat to com-
pletely dry before spraying on the second. Use
top coat with appropriate gloss level to match adjacent similar components. This
clear coat is
necessary to control the gloss requirement and
prevent
'tracking" (rubbing-off) of the color
coat after drying.
4. Allow to dry according to label directions before
installing part.
ON-VEHICLE SERVICE
CONCEALED HEADLIGHTS
The concealed headlights used on this model are
electrically operated. When the headlights are turned
on, solid state circuitry activates the actuators. This
same circuitry senses when the actuators stop moving
and removes the ground to deactivate the actuators.
When the headlights are turned off, the actuators run
in opposite direction closing the headlight doors.
Should an electrical failure occur in the head-
light circuit, they may be raised manually by rotating
the knob on the actuator in a counterclockwise direc-
tion until the headlights are fully open. The headlights
may be lowered by rotating the knob on the actuator in
a clockwise direction until the headlights are fully
closed.
For electrical circuit information and diagnosis,
refer to Section
8A of this manual.
If it is desired to raise the headlights with the
lights off, either of the following procedures may be
used:
1. Turn the lights on. After the headlights are
open, disconnect the electrical connections at
the actuator connectors. Turn the lights off. The
headlights will now remain in the open position.
2. Turn the parking lights on. Depress the head-
light rocker switch lightly. The headlights may
then be raised "up" fully with the lights off.
Adjust
Because of the number of adjustments possible
and the number of attaching points of the concealed
headlight body assembly
(9), only those attachments
which control the adjustment desired should be loos-
ened. Make one
adjbstment at a time.
NOTICE: The headlight door does NOT have
slotted mounting holes and therefore is not
adjustable by itself. This insures proper clearance
between the headlight door and the hood and
fenders in both the raised and lowered positions.
The entire headlight body assembly must be
adjusted to achieve the desired appearance and
fit. Care should be exercised when adjusting the
headlight body assembly. Severe hammer blows could damage the die cast aluminum headlight
body assembly.
TO RAISE OR LOWER the headlight body
assembly, proceed as follows:
1. Open hood.
2. Raise headlights.
