### Removal Procedure

Caution: Refer to Battery Disconnect Caution in the Preface section.

1. Disconnect the negative battery cable.
2. Recover the refrigerant.
3. Remove the compressor. Refer to Air Conditioning Compressor Replacement .
4. Remove the clutch drive plate and hub assembly. Refer to Compressor Clutch Plate/Hub Assembly Replacement .
5. Remove the pulley rotor and bearing assembly retaining ring using the J 6083 (1).
6. With the compressor mounted to the J 34992 (2), install the J 33020 (1) into the inner circle of slots in the pulley rotor. Turn the J 33020 (1) clockwise in the slots to engage the puller tangs with the segments between the slots in the rotor.
7. Hold the J 33020 (1) in place and tighten the puller bolt against the compressor shaft to remove the pulley rotor and bearing assembly.

Notice: Do not support the rotor/hub assembly by resting the compressor pulley on a flat surface. Always support the rotor/hub assembly by securely resting the hub on a stable flat surface. The compressor pulley face could be damaged.

8. Remove the puller bolt from the J 33020 (3). With the puller tangs still engaged in the rotor slots, invert the assembly onto a solid flat surface or blocks.

Notice: When removing the bearing, it is not necessary to remove the staking in front of the bearing. 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.

9. Drive the bearing out of the rotor hub with the J 9398-A (2) and the J 8092 (1).

### Installation Procedure

Notice: Do not support the rotor/hub assembly by resting the compressor pulley on a flat surface. Always support the rotor/hub assembly by securely resting the hub on a stable flat surface. The compressor pulley face could be damaged.

1. Invert the pulley rotor and place it on a support block to fully support the rotor hub during bearing installation.
2. Align the new bearing squarely in the pulley bore. Use the J 9481-B (2) and the J 8092 (1), drive the bearing fully into the pulley bore.
3. Place the J 33019 (1, 2) in the rotor hub core. Shift the rotor and bearing assembly on the block to give full support to the hub under the staking pin. A heavy-duty rubber band may be used to hold the staking tool pin in the guide. The pin should be properly positioned in the guide after each impact on the pin.
4. Strike the pin with a hammer until a metal stake, similar to the original, is formed down to, but not touching, the bearing. The metal stake should not contact the outer race of the bearing to avoid the possibility of distorting the outer race. Stake in 3 places 120 degrees apart.
5. With the compressor mounted to the J 34992 (3), position the rotor and bearing assembly on the compressor housing.
6. Position the J 33017 (4) and the J 33023-A (2) directly over the inner race of the bearing.
7. Position the J 8433-1 (5) center forcing bolt on the J 33023-A (2) and assemble the 2 through-bolts and the washers through the slots on the J 8433-1 (5). Thread the through-bolts into the J 34992 (3). The thread of the through-bolts should engage the full thickness of the fixture.
8. Tighten the J 8433-3 (1) in the J 8433-1 (5) to force the pulley rotor and bearing assembly onto the compressor housing.
9. Install the rotor and bearing assembly retainer ring using the J 6083 (1).
10. Reinstall the clutch drive plate and hub assembly. Refer to Compressor Clutch Plate/Hub Assembly Replacement .
11. Install the compressor. Refer to Air Conditioning Compressor Replacement .
12. Connect the negative battery cable.
13. Evacuate and recharge the A/C system. Refer to Refrigerant Recovery and Recharging .
