Compressor Clutch Coil Install (HT6/HD6/HU6)

Tools Required 

• J 33024  Clutch Coil Installer Adapter
• J 8433-1  Puller Bar
• J 8433-3  Forcing Screw
• J 34992  Compressor Holding Fixture
• J 33017  Pulley and Bearing Assembly Installer
• J 33023-A  Puller Pilot
• J 6083  External Snap Ring Pliers

1. Place the clutch coil assembly (1) on the front head. Position the terminals at the marked location.
2. Place the J 33024  over the internal opening of the clutch coil housing.
3. Align the J 33024  with the compressor front head.
4. Center the J 8433-1  in the counter-sunk center hole of the J 33024. 
5. Install the 2 through bolts and washers through the crossbar slots.
6. Thread the bolts into the J 34992  in order to achieve full fixture thickness.
7. Turn the center forcing screw of the J 8433-1  in order to force the clutch coil onto the front head. Ensure that the clutch coil and the J 33024  remain aligned during installation.

8. When the coil is fully seated on the front head, use a 1/8 inch diameter drift punch (2) in order to stake the front head at 3 places 120 degrees apart (3), in order to ensure that the clutch coil (1) remains in position.
9. Ensure that the stake size is only one-half the area of the punch tip. Ensure that the stake is only approximately 0.28-0.35 mm (0.010-0.015 in) deep.

10. With the compressor mounted to the J 34992,  position the pulley rotor (1) and bearing assembly on the front head.
11. Position the J 33017  and the J 33023-A  directly over the inner race of the bearing.
12. Position the J 8433-1  on the J 33023-A. 
13. Assemble the 2 through bolts and washers through the puller bar slots.
14. Thread the bolts into the J 34992.  Ensure that the thread of the through bolts engages the full thickness of the J 34992. 
15. Tighten the center screw in the J 8433-1  in order to force the pulley rotor and bearing assembly onto the compressor front head. If the J 33017  slips off direct in-line contact with the inner race and bearing, perform the following steps:
    1. 15.1. Loosen the J 8433-3. 
    2. 15.2. Realign the installer and the pilot in order to ensure that the J 33017  properly clears the front head.
