Tools Required 

  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.

  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.
  16. Use the J 6083  in order to install the following components:
    • The pulley rotor (1)
    • The retainer ring (2)
