CAUTION: If the center screw is threaded fully onto
the end of the compressor shaft. or if the body of
the installer is held and the center screw is rotated,
the key will wedge and will break the clutch hub.7. Remove installer J-33013-B, check for proper
positioning of the shaft key (even or slightly above
the clutch hub).
8. Spin the pulley rotor by hand to see that the rotor is
not rubbing the clutch drive plate.

BEARING
Removal
1. Remove the clutch plate and hub assembly as
described previously.
2. Remove rotor (1) and bearing assembly retaining
ring (2), using snap ring pliers.
3. Install pulley rotor and bearing puller guide J-33023-A
to the front head and install J-41552 pulley rotor and
bearing puller down into the inner circle of slots (1) in
the rotor. Turn the J-41552 puller clockwise in the
slots in the rotor.4. Hold the J-41552 puller in place and tighten the
puller screw against the puller guide to remove the
pulley rotor and bearing assembly.
Installation
1. With the compressor mounted to the J-34992
holding fixture, position the rotor and bearing
assembly on the front head.
2. Position the J-33017 pulley, rotor and bearing
installer and J-33023-A puller pilot directly over the
inner race of the bearing.

COMPRESSOR SHAFT SEAL
Service Precaution
When replacing the shaft seal assembly, pressure relief
valve or control switches, it will be necessary to recover
the refrigerant. Other than clutch repair procedures, the
same holds true for any disassembly of the compressor.
A clean workbench covered with a sheet of clean
paper, and a place (clean trays, etc) for all parts being
removed and replaced is important, as is the use of
proper clean service tools.
CAUTION: Any attempt to use makeshift or
inadequate service tools or equipment may result
in damage and/or improper compressor operation.
All parts required for servicing the internal compressor
are protected by a preservative 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 intact until just
prior to installation.
If the compressor rear head, front head or cylinder and
shaft assembly is to be serviced or replaced, the oil in
the compressor must be drained, measured, recorded
and replaced.

Seal Leak Detection
A shaft seal should not be changed because of small
amounts of oil found on an adjacent surface but only
after actual refrigerant leakage is found using an
approved leak detector.
CAUTION: Handling and care of seal protector is
important. If seal protector is nicked or the bottom
flared, the new seal may be damaged during
installation.
Removal
1. Recover the refrigerant using Refrigerant Recovery
System.
2. Loosen and reposition compressor in mounting
brackets, if necessary.
3. Remove clutch plate and hub assembly from
compressor as described previously.
4. Remove the shaft seal retainer ring, using snap ring
pliers.
5. Thoroughly clean inside of compressor neck area
surrounding the shaft, the exposed portion of the
seal, the retainer ring groove and the shaft itself.
Any dirt or foreign material getting into compressor
may cause damage.
6. Fully engage the knurled tangs of Seal Remover-
Installer J-23128-A into the recessed portion of the
Seal (1) 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. Remove and discard the seal seat O-ring (2) from the
compressor neck using O-ring remover J-9553-01.
8. Recheck the shaft and inside of the compressor
neck for dirt or foreign material and be sure these
areas are perfectly clean before installing new parts.
Cleaning
Thoroughly clean O-ring seal groove in front head.
CAUTION: Seals should not be re-used. Always use
a new specification service seal on rebuild. Be sure
that the seal to be installed is not scratched or
damaged in anyway. Make sure that the seal seat
and seal are free of lint and dirt that could damage
the seal surface or prevent sealing.
Installation
1. Dip the new seal seat O-ring (1) in clean 525
viscosity refrigerant oil and assemble onto O-ring
installer J-33011.2. Insert the O-ring installer J-33011 into the
compressor neck until the installer "bottoms". Lower
the moveable slide of the O-ring installer to release
the O-ring into the seal 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. Dip the new seal in clean 525 viscosity refrigerant oil
and assemble seal to Seal Installer J-23128-A, by
turning handle clockwise. 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. Install
seal protector J-34614, in the seal lip and place over
the compressor shaft, and push the seal in place with
a rotary motion or place the seal protector J-34614
over end of compressor shaft, and slide the new seal
onto the shaft with a rotary motion until it stops. Take
care not to dislodge the O-ring. Be sure the seal (2)
makes good contact with the O-ring. Disengage the
installer from the seal and remove the installer
J-23128-A and the seal protector J-34614.
CAUTION: Handling and care of seal protector is
important. If seal protector is nicked or the bottom
flared, the new seal may be damaged during
installation.
4. Install the new seal retainer ring with its flat side
against the Seal, using Snap-Ring Pliers. Use the
sleeve from O-ring installer J-33011 to press in on
the seal retainer ring so that it snaps into its groove.
5. To leak test, install compressor leak test fixture
J-39893 on rear head of compressor and connect
gage charging lines and Refrigerant Recovery
System. Pressurize suction and high-side of
compressor with R-134a Refrigerant. Temporarily
install (M9
1.25 thread on shaft) nut and, with the
compressor in horizontal position, rotate the
compressor shaft in normal direction of rotation
several times by hand. Leak test the seal area and
correct and leak found. Recover the refrigerant.
Remove shaft nut.
