## Compressor Clutch Plate/Hub Assembly Install V5 - Conventional Mount

#### Tools Required

• | J 33013-B Hub and Drive Plate Remover/Installer

• | J 33022 6-Shaft Nut Socket - 13mm

• | J 33027-A Clutch Hub Holding Tool

• | J 34992 Compressor Holding Fixture

1. Install the compressor into the J 34992 .
2. 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.

3. Clean the frictional surfaces of the clutch plate and hub and the clutch pulley rotor (2).
4. 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.

5. Place the clutch plate and hub assembly onto the compressor shaft.
6. Remove the center screw from the J 33013-B .
7. Reverse the body direction of the center screw of the J 33013-B .
8. Install the J 33013-B with the bearing.
9. Back off the body of the J 33013-B in order to allow the center screw to be threaded onto the end of the compressor shaft.
10. Hold the center screw of the 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.

11. Tighten the hex portion of the body of the J 33013-B in order to press the hub onto the shaft.
12. Tighten the body of the J 33013-B several turns.
13. Remove the J 33013-B .
14. Verify that the shaft key remains in the keyway before installing the clutch plate and hub assembly to the final position.
15. 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).
16. Remove the J 33013-B .
17. Verify that the shaft key is even with or slightly above the clutch hub.
18. Install the shaft nut.
19. Hold the clutch plate and hub assembly with the 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.

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

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

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

## Compressor Clutch Plate/Hub Assembly Install V7 - Direct Mount

#### Tools Required

• | J 33013-B Hub and Drive Plate Remover/Installer

• | J 33017 Pulley and Bearing Assembly Installer

• | J 33027-A Clutch Hub Holding Tool

1. Install the shaft key into the hub key groove (4) approximately 3.2 mm (1/8 in) out of the keyway.

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

2. Clean the surfaces of the clutch plate (1) and the clutch rotor (2) before installing the clutch plate and hub assembly.
3. Align the shaft key with the shaft keyway in the clutch plate and the hub assembly and place onto the A/C compressor shaft (3).
4. Remove the J 33013-B .

4.1. | Remove the center screw from the body of the J 33013-B .

4.2. | Install the center screw into the opposite end of the J 33013-B .

5. Install the J 33013-B and bearing tools (1) onto the clutch plate (3) and the hub assembly (2).

5.1. | Back the body of the J 33013-B off enough to allow the center screw to be threaded onto the end of the A/C compressor shaft.

5.2. | Thread the center screw several turns onto the end of the A/C compressor shaft.

Do not tighten the center screw on the A/C compressor shaft.

6. Hold the center screw with a wrench.

6.1. | Tighten the hex portion of the J 33013-B body several turns.

6.2. | Remove the J 33013-B from the clutch plate and hub.

6.3. | Make sure that the shaft key is still in place in the keyway.

7. Reinstall the J 33013-B .
8. Place a feeler gage between the clutch plate and the clutch rotor.

Important: Make sure that the air gap is even all around the clutch plate and hub assembly.

9. Tighten the hex portion of the J 33013-B until the air gap between the clutch plate and clutch rotor is 0.40 mm (0.015 in).
10. Remove the J 33013-B .
11. Hold the clutch plate and hub assembly (2) with the 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.

12. Install the A/C compressor shaft nut.

Tighten
Tighten the nut to 17.5 N·m (13 lb ft).

13. Spin the pulley rotor by hand to make sure the rotor is not rubbing against the clutch drive plate.
14. Remove the A/C compressor from the J 41790-A .
15. Install the A/C compressor into the vehicle.
