Compressor Clutch Plate/Hub Assembly Install HT6/HD6/HU6

Tools Required

J 33013-B Hub and Drive Plate Remover/Installer

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

Allow the key to project approximately 3.2 mm (0.125 in) out of the keyway (3). The shaft key curves slightly in order to provide an interference fit in the hub key groove.

2. Clean the following components:

•	The clutch plate

•	The clutch rotor (2)

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



5. Remove the forcing tip on the J 33013-B .
6. Reverse the body direction on the center screw.
7. Install the J 33013-B with the bearing.
8. 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.
9. Hold the center screw with a wrench.
10. Tighten the hex portion of the J 33013-B body in order to press the hub onto the shaft.
11. Tighten the body several turns.
12. Remove the installer. Ensure that the shaft key remains in place in the keyway.
13. Install the clutch plate and hub assembly to the final position.

Ensure that the air gap (2) between frictional surfaces of the clutch plate and clutch rotor measures within 0.50-0.76 mm (0.020-0.030 in).

14. Remove the J 33013-B .
15. Verify proper positioning of the shaft key.

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

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

Compressor Clutch Plate/Hub Assembly Install V7 - Direct Mount

Tools Required

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.
