Disassembly Procedure
1. Disconnect the negative battery cable.
2. Recover the refrigerant.
3. Remove the compressor.
4. Remove the clutch drive plate and the hub assembly.
5. Remove the pulley rotor and the bearing assembly retaining ring using the snap ring pliers J-6083.
6. Install the pulley puller J-33020 into the inner circle of slots in the pulley rotor. Turn the pulley puller J-33020 clockwise in the slots to engage the puller tangs with the segments between the slots in the rotor.
7. Hold the pulley puller J-33020 in place and tighten the puller bolt against the compressor shaft to remove the pulley rotor and the bearing assembly.
NOTE: The rotor hub must be properly supported to prevent damage to the pulley rotor during bearing removal.
8. Remove the puller bolt from the pulley puller J-33020. With the puller tangs still engaged in the rotor slots, invert the assembly onto a solid flat surface or blocks.
NOTE: It is not necessary to remove the staking in front of the bearing to remove 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 bearing remover J-9398-A and the driver handle J-8092.
Assembly Procedure
NOTE: Do not support the rotor by resting the pulley rim on a flat surface during the bearing installation or the rotor 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 bearing installer J-9481 and the driver handle J-8092, drive the bearing fully into the pulley bore.
3. Place the bearing staking guide J-33019-1 and the bearing staking pin J-33019-2 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 location. 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.
CAUTION: When striking the pin with a hammer, take care to avoid personal injury.
4. Strike the pin with a hammer until a metal slake, 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 three places, each 120 degrees apart.
5. With the compressor mounted to the holding fixture J-34992, position the rotor and the bearing assembly on the compressor housing.
6. Position the pulley rotor and bearing assembly installer J-33017 and the puller pilot J-33023-A directly over the inner race of the bearing.
7. Position the puller crossbar J-8433-1 center forcing bolt on the puller pilot J-33023-A and assemble the two through-bolts and the washers through the puller crossbar J-8433-1 slots. Thread them into the holding fixture. The thread of the through-bolts should engage the full thickness of the fixture.
8. Tighten the center forcing screw J-8433-3 in the puller crossbar J-8433-1 to force the pulley rotor and the bearing assembly onto the compressor housing.
9. Install the rotor and the bearing assembly retainer ring using the snap ring pliers J-6083.
10. Reinstall the clutch drive plate and hub assembly.
11. Install the compressor.
12. Connect the negative battery cable.
13. Evacuate and recharge the A/C system.
