COMPRESSOR CLUTCH PLATE AND HUB
ASSEMBLY
Removal
1. Clamp the holding fixture J-33026 in a vise and
attach compressor to holding fixture with thumb
screws J-33026-1.
2. With center screw forcing tip in place to thrust
against the end of the shaft, thread the Clutch Plate
and Hub Assembly Installer-Remover J-33013-B into
the hub. Hold the body of the remover with a wrench
and turn the center screw into the remover body to
remove the clutch plate and hub assembly (1).
CAUTION: Do not drive or pound on the clutch hub
or shaft. Internal damage to compressor may
result. The forcing tip on J-33013-B remover-
installer center screw must be flat or the end of the
shaft/axial plate assembly will be damaged.
3. Remove the shaft key and retain for reassembly.
Installation
1. Install the shaft key into the hub key groove. Allow
the key to project approximately 3.2 mm (1/8 in) out
of the keyway. The shaft key is curved slightly to
provide an interference fit in the hub key groove.2. Be sure the frictional surface of the clutch plate and
the clutch rotor (2) are clean before installing the
clutch plate and hub assembly (1).
3. Align the shaft key (4) with the shaft keyway (3) and
place the clutch plate and the hub assembly onto
the compressor shaft.
4. Remove the forcing tip on J-33013-B clutch plate
and hub assembly installer-remover center screw
and reverse the body direction on the center screw,
as shown in Figure.
5. Install the clutch plate and hub installer-remover J-
33013-B with bearing as shown in Figure.
The body of the J-33013-B installer-remover should
be backed off sufficiently to allow the center screw to
be threaded onto the end of the compressor shaft.
6. Hold the center screw with a wrench. Tighten the
hex portion of the installer-remover J-33013-B body
to press the hub onto the shaft. Tighten the body
several turns, remove the installer and check to see
that the shaft key is still in place in the keyway
before installing the clutch plate and hub
assembly to its finial position.The air gap (2)
between frictional surfaces of the clutch plate and
clutch rotor should be 0.50–0.76 mm (.020–.030 in).

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.
COMPRESSOR CLUTCH ROTOR AND/OR
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.

3. Position puller crossbar J-8433-1 on the puller pilot
J-33023-A and assemble the two J-33026 through
bolts and washers through the puller bar slots and
thread them into the J-33026 holding fixture. The
thread of the through bolts should engage the full
thickness of the holding fixture.
4. Tighten the center screw in the J-8433-1 puller
crossbar to force the pulley rotor (1) and bearing
assembly onto the compressor front head. Should
the J-33017 pulley rotor and bearing installer slip off
direct in-line contact with the inner race of the
bearing, loosen the J-8433-1 center forcing screw
and realign the installer and pilot so that the J-
33017 installer will properly clear the front head.5. Install rotor and bearing assembly retainer ring,
using snap ring pliers.
6. Reinstall clutch plate and hub assembly as
described previously.
COMPRESSOR CLUTCH COIL
Removal
1. Perform Steps 1 through 4 of "Clutch Rotor and/or
Bearings" removal procedure. Mark clutch coil
terminal location (1) on compressor front head.
2. Install J-33023-A puller pilot on front head of
compressor. Also install J-8433-1 puller crossbar
with J-33025 puller legs as shown in figure.
3. Tighten J-8433-3 forcing screw against the puller
pilot to remove the clutch coil (2).

Installation
1. Place the clutch coil assembly (1) on the front head
with the terminals positioned at the "marked" location.
2. Place the J-33024 clutch coil installer over the
internal opening of the clutch coil housing and align
installer with the compressor front head.
3. Center the J-8433-1 puller crossbar in the counter-
sunk center hole of the J-33024 clutch coil installer.
Install the J-33026 through bolts and washers
through the crossbar slots and thread them into the
holding fixture J-33026 to full fixture thickness.
4. Turn the center forcing screw of J-8433-1 puller
crossbar to force the clutch coil onto the front head.
Be sure clutch coil and J-33024 installer stay "in-
line" during installation.
5. When coil is fully seated on the front head, use a
1/8 in diameter drift punch (2) and stake the front
head at three places 120 degrees apart, to ensure
clutch coil (3) remains in position.
Stake size should be only one-half the area of the
punch tip and be only approximately 0.28–0.35
mm (.010–.015 in) deep.

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.
