Tools Required

1. Remove the air compressor from the vehicle. Refer to Air Conditioning Compressor Replacement .
2. Use the J 34992 in order to install the compressor in the vise.
3. Use both thumb screws in order to attach the compressor to the J 34992 .
4. Remove the shaft protector from the clutch hub shaft.




Notice: Do not drive or pound on the clutch hub or shaft. Internal damage to the compressor may result. The forcing tip on the J 33013-B remover/installer center screw must be flat or the end of the shaft/axial plate assembly will be damaged.

5. Ensure that the center screw forces the tip to thrust against the end of the shaft.
6. Thread the J 33013-B into the hub.
7. While holding the body of the J 33013-B of the remover with a wrench, turn the center screw into the remover body in order to remove the clutch plate and hub assembly (1).



8. Remove the shaft key (4). Retain the shaft key for reassembly.
9. Remove the old clutch plate and hub assembly from the compressor.

1. Install the new clutch plate and hub assembly to the compressor.



2. Install the shaft key (4) into the hub key groove.

Allow the key to project approximately 0.50-0.76 mm (0.020-0.030 in) out of the keyway (3). The shaft key curves slightly in order to provide an interference fit in the hub key groove.

3. Clean the following components:

•	The clutch plate

•	The clutch rotor (2)

4. Align the shaft key (4) with the shaft keyway (3).
5. Place the clutch plate and the hub assembly (1) onto the compressor shaft.



6. Install the forcing tip on the J 33013-B .
7. Reverse the body direction on the center screw.
8. Install the J 33013-B with the bearing (1).
9. Back off the body of the J 33013-B as necessary in order to permit the center screw to be threaded onto the end of the compressor shaft.
10. Hold the center screw with a wrench.
11. Tighten the hex portion of the J 33013-B body in order to press the hub onto the shaft.
12. Tighten the body several turns.
13. Install the clutch plate and hub assembly to the final position.
14. Inspect the air gap (2).



15. Ensure that the air gap between frictional surfaces of the clutch plate and clutch rotor measures within 3.81-5.08 mm (0.15-0.20 in).
16. Check the clutch plate and hub assembly in three places for clearance.
17. Remove the installer. Ensure that the shaft key remains in place in the keyway.
18. Remove the J 33013-B .
19. Verify proper positioning of the shaft key.

Ensure that the shaft key is even with or slightly above the clutch hub.

20. Spin the pulley rotor by hand in order to verify that the rotor does not rub against the clutch drive plate.
21. Install the shaft protector to the clutch hub shaft.
22. Remove both thumb screws from the compressor to the J 34992 .
23. Remove the J 34992 from the compressor and the vise.
24. Install the air compressor to the vehicle. Refer to Air Conditioning Compressor Replacement .
25. Evacuate and recharge the refrigerant system. Refer to Refrigerant Recovery and Recharging .
26. Leak test the fitting(s) of the repaired or reinstalled component using the J 39400-A .
