J-9481 Bearing Installer
J-33020 Pulley Puller
J-33023-A Puller Pilot
J-33019 Bearing Staking Tool Set
Includes: J-33019-1 Bearing Staking Guide
Includes: J-33019-2 Bearing Staking Pin
J-33017 Pulley Rotor and Bearing Installer
J-8433-1 Puller Crossbar
J-34992 Compressor Holding Fixture
J-8092 Driver Handle
J-8433-3 Forcing Screw
Disassembly
1. Disconnect the negative battery cable.
2. Recover the refrigerant. Refer to Discharging, Adding Oil, Evacuating, and Charging Procedures for A/C system.
3. Remove the compressor.
4. Remove the clutch drive plate and hub assembly.
5. Remove the pulley rotor and bearing assembly retaining ring using the snap ring pliers J-6083.
6. With the compressor mounted to the compressor holding fixture J-34992, 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 bearing assembly.
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.
9. Drive the bearing out of the rotor hub with the bearing remover J-9398-A and the driver handle J-8092.
Installation
CAUTION: 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. 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 three places 120 degrees apart.
5. With the compressor mounted to the holding fixture J-34992, position the rotor and bearing assembly on the compressor housing.
6. Position the pulley rotor and bearing 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 slots on the puller crossbar J-8433-1. Thread the through-bolts into the holding fixture J-34992. 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 bearing assembly onto the compressor housing.
9. Install the rotor and 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. Refer to Discharging, Adding Oil, Evacuating, and Charging Procedures for A/C system.
