Compressor Clutch Bearing: Service and Repair

Remove or Disconnect

1. Remove the clutch plate and hub assembly as described previously.
2. Remove rotor and bearing assembly retaining ring, using snap ring pliers J 6083.
3. Install pulley rotor and bearing pulley guide J 33023-A to the front head and install J 33020 pulley rotor and bearing pulley down into the inner circle of slots in the rotor. Turn the J 33020 pulley clockwise in the slots to engage the pulley tangs with the segments between the slots in the rotor.
4. Hold the J 33020 pulley in place and tighten the pulley screw against the pulley guide to remove the pulley rotor and bearing assembly.
5. To prevent damage to the pulley rotor during bearing removal the rotor hub must be properly supported.
Remove the forcing screw from J 33020 pulley and, with the pulley tangs still engaged in the rotor slots, invert the assembly onto a solid flat surface or blocks as shown in image.
6. Drive the bearing out of the rotor hub with rotor bearing remover J 9398-A and J 29886 universal handle.

NOTICE: It is not necessary to remove the staking in front of the bearing to remove the bearing, however, it will be necessary to file away the old stake metal for proper clearance for the new bearing to be installed into the rotor bore or the bearing may be damaged.














Install or Connect

1. Place the pulley rotor on the J 21352-A support block to fully support the rotor hub during bearing installation.

NOTICE: Do Not support the rotor by resting the pulley rim on a flat surface during the bearing installation or the rotor face will be bent.

2. Align the new bearing squarely with the hub bore and using pulley and bearing installer J 9481-A with universal handle J 29886, drive the bearing fully into the hub. The installer will apply force to the outer race of the bearing if used as shown.
3. Place bearing staking guide J 33019-1 and bearing staking pin J 33019 in the hub bore as shown in image. Shift the rotor and bearing assembly on the J 21352-A support block to give full support of the hub under the staking pin location. A heavy-duty rubber band may be used to hold the stake pin in the guide, and the stake pin should be properly positioned in the guide after each impact on the pin.
4. Using care to prevent personal injury, strike the staking pin with a hammer until a metal stake, similar to the original, is formed down to but not touching the bearing.
The stake metal should not contact the outer face of the bearing to prevent the possibility of distorting the outer race. Stake three (3) places 120° apart.
5. With the compressor mounted to the J 34992 holding fixture, position the rotor and bearing assembly on the front head.
6. Position the J 33017 pulley rotor and bearing installer and J 33023-A pulley pilot directly over the inner race of the bearing.
7. Position pulley crossbar J 8433-1 on the pulley pilot J 33023-A and assemble the two J 34992-2 through bolts and washers through the pulley bar slots and thread them into the J 34992 holding fixture. The thread of the through bolts should engage the full thickness of the holding fixture.
8. Tighten the center screw in the J 8433-1 pulley crossbar to force the pulley rotor 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 face of the bearing, loosen the J 8433-3 center forcing screw and realign the installer and pilot so that the J 33017 installer will properly clear the front head.
9. Install rotor and bearing assembly retainer ring, using snap ring pliers J 6083.
10. Reinstall clutch plate and hub assembly.
