    Notice: It is not necessary to remove the staking in front of the bearing to remove the bearing, however, it will be necessary to file away the old stake metal for proper clearance for the new bearing to be installed into the rotor bore or the bearing may be damaged.

  14. Use a J 9398 with the J 8092 in order to drive the bearing out of the rotor hub.

Installation Procedure


    Object Number: 210146  Size: SH

    Notice: Do not support the rotor by resting the pulley rim on a flat surface during the bearing installation or the rotor face will be bent.

  1. Place the pulley rotor on the J 21352-A in order to fully support the rotor hub during the bearing installation.
  2. Align the new bearing with the hub bore.
  3. Using the J 9481-A and the J 8092 , drive the bearing into the hub.
  4. The J 9481-A applies force to the outer race of the bearing.

  5. Place the J 33019 and the staking pin in the hub bore.
  6. Shift the rotor and bearing assembly on the J 21352-A in order to fully support the hub under the location of the staking pin.
  7. Use a heavy-duty rubber band (1) in order to hold the stake pin in the guide of the J 33019 .
  8. Important: Do not allow a metal stake to contact the outer face of the bearing in order to prevent distortion of the outer race.

  9. Using care in order to prevent injury, strike the staking pin of the J 33019 . Properly position the stake pin in the guide after each impact on the pin.
  10. Continue to strike the pin of the J 33019 until a stake, similar to the original stake, is formed down to, but not touching, the bearing.

  11. Object Number: 6147  Size: SH
  12. Stake 3 places 120 degrees apart.

  13. Object Number: 237122  Size: SH
  14. With the compressor mounted to the J 34992 , position the rotor and bearing assembly on the front head.
  15. Position the J 33017 and the J 33023-A directly over the inner race of the bearing.
  16. Position the J 8433-1 on the J 33023-A .
  17. Assemble the 2 through bolts and the washers of the J 34992 through the slots of the J 8433-1 .
  18. Thread the 2 through bolts into the J 34992 .
  19. Ensure that the thread of the through bolts engages the full thickness of the J 34992 .

  20. Tighten the J 8433-3 in the J 8433-1 in order to force the pulley rotor and bearing assembly onto the front head of the compressor.
  21. If the J 33017 slips off direct, in-line contact with inner face of the bearing, use the following steps:
  22. 16.1. Loosen the J 8433-3 .
    16.2. Realign the J 33017 and the J 33023-A in order to ensure that the installer clears the front head.
