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).

7. Remove installer J-33013-B, check for proper

positioning of the shaft key (even or slightly above
the clutch hub).

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.
