Tools Required

1. Install the shaft key (4) into the key groove of the clutch plate and hub (1).

•	Allow the key to project 3.2 mm (0.126 in) out of the key groove.

•	The shaft key is curved slightly in order to provide an interference fit in the key groove of the hub.

2. Clean the frictional surfaces of the clutch plate and hub and the clutch pulley rotor (2).
3. Align the shaft key with the shaft keyway (3).

Notice: Do not drive or pound on the clutch hub or the shaft. Internal damage to the compressor may result.

4. Place the clutch plate and hub assembly onto the compressor shaft.



5. Remove the center screw from J 33013-B .
6. Reverse the body direction of the center screw of J 33013-B .
7. Install J 33013-B with the bearing.
8. Back off the body of J 33013-B in order to allow the center screw to be threaded onto the end of the compressor shaft.
9. Hold the center screw of J 33013-B with a wrench.

Notice: If the center screw is threaded fully onto the end of the compressor shaft, or if the body of the installer is held and the center screw is rotated, the key will wedge and will break the clutch hub.

10. Tighten the hex portion of the body of J 33013-B in order to press the hub onto the shaft.
11. Tighten the body of J 33013-B several turns.
12. Remove J 33013-B .
13. Verify that the shaft key remains in the keyway before installing the clutch plate and hub assembly to the final position.
14. Ensure that the gap between the frictional surfaces of the clutch plate and the clutch rotor is within 0.40-0.50 mm (0.016-0.020 in).
15. Remove J 33013-B .
16. Verify that the shaft key is even with or slightly above the clutch hub.
17. Install the shaft nut.
18. Hold the clutch plate and hub assembly with J 33027-A .

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

19. Tighten the shaft nut against the crankshaft shoulder, using a 17.5 N·m (12.5 lb ft) torque wrench and J 33022 .

Tighten
Tighten the nut to 16.5 N·m (12 lb ft).

20. Spin the pulley rotor by hand in order to verify that the rotor does not rub the clutch drive plate.
