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.

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.

LEAK TESVING (EXTERNAL AND INTERNAL)
Bench-Check Procedure
1. Install Test Plate J-9625-A on Rear Head of
compressor.
2. Attach center hose of Manifold Gage Set on
Charging Station to a refrigerant drum standing
in an upright position and open valve on drum.
3. Connect Charging Station high and low pressure
lines to corresponding fittings on Test Plate J-9625-A, using
5-5420 Gage
Adapters if hoses
are not equipped with valve depressors.
Suction port (low-side) of compressor has
large internal opening. Discharge port
(hi-side) has smaller internal opening into
compressor.
Open low-pressure control, high-pressure control
and refrigerant control on Charging Station to
allow refrigerant vapor to flow into compressor.
Using a Leak Detector, check for leaks at
Pressure Relief Valve, compressor shell to
cylinder, compressor front head seal, and
compressor Shaft Seal. After checking, shut off
low pressure control and high pressure control on
Charging Station.
If an external leak is present, perform the
necessary corrective measures and recheck for
leaks to make certain the leak has been corrected.
Loosen the Manifold Gage hose connections to
the Gage Adapters J-5420 connected to the low
and high sides and allow the vapor pressure to
release from the compressor.
Disconnect both Gage Adapters
5-5420 from the
Test Plate J-9625-A.
Rotate the complete compressor assembly (not
the crankshaft or drive plate hub) slowly several
turns to distribute oil to all cylinder and piston
areas.
Install a shaft nut on the compressor crankshaft
if the drive plate and clutch assembly are not
installed.
Using a box-end wrench or socket and handle,
rotate the compressor crankshaft or clutch drive
plate on the crankshaft several turns to ensure
piston assembly to cylinder wall lubrication.
Connect the Charging Station high pressure line
or a high pressure gage and Gage Adapter J-5420
to the Test Plate J-9625-A high side connector.
Attach an Adapter
9-5420 to the suction or low
pressure port of the Test Plate
J-9625-19 to open
the Schrader-type valve.
Oil will drain out of the compressor suction port
adapter if the compressor is positioned with the
suction port downward.
Attach the compressor to the Holding Fixture
J-25008-A using metric mounting screws. Clamp
the compressor Holding Fixture in a vise so that
the compressor can be manually turned with a
wrench.
Using a wrench, rotate the compressor crankshaft
or drive plate hub ten complete revolutions at a
speed of approximately one-revolution per
second.
Turning the compressor at less than
one-revolution per second can result in a lower
pump-up pressure and disqualify a good pumping
compressor.
Observe the reading on HIGH pressure gage at
the completion of the tenth revolution of the
compressor. The pressure reading for a good
pumping compressor should be 344.75
kPa (50 p.
s.i.) or above. A pressure reading of less than 3 10.
275 kPa (45 p.s.i.) would indicate one or more

101.20 R-4 AIR CONDITIONING COMPRESSOR OVERHAUL
suction and/or discharge valves leaking, an
internal leak or an inoperative valve, and the
compressor should be disassembled and checked
for cause of leak. Repair as needed, reassemble
and repeat the pump-up test. Externally leak test.
When the pressure pump-up test is completed,
release the air pressure from the HIGH side and
remove the Gage Adapters J-5420 and Test Plate
J-9625-A. 18. On the R-4 compressor, tilt the compressor so
that the compressor suction and discharge ports
are down. Drain the oil from the compressor.
19. Allow the compressor to drain for
10 minutes,
then charge with the proper amount of oil. The
oil may be poured into the suction port.
If further assembly or processing is required, a
shipping plate or Test Plate J-9625-A should be
installed to keep out air, dirt and moisture until
the compressor is installed.
