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

  1. Invert the pulley rotor and place it on a support block to fully support the rotor hub during bearing installation.
  2. Align the new bearing squarely in the pulley bore. Use the J 9481-A  (2) and the J 8092  (1), drive the bearing fully into the pulley bore.

  3. Object Number: 1251993  Size: SH
  4. Place the J 33019  (1) and the J 33019  (2) in the rotor hub core. Shift the rotor and bearing assembly on the block to give full support to the hub under the staking pin location. A heavy-duty rubber band may be used to hold the staking tool pin in the guide. The pin should be properly positioned in the guide after each impact on the pin.

  5. Object Number: 1251995  Size: SH
  6. Strike the pin with a hammer until a metal stake, similar to the original, is formed down to, but not touching, the bearing. The metal stake should not contact the outer race of the bearing to avoid the possibility of distorting the outer race. Stake in 3 places 120° apart.

  7. Object Number: 1251996  Size: SH
  8. With the compressor mounted to the J 42428  (3), position the rotor and the bearing assembly on the compressor housing.
  9. Position the J 33017  (4) and the J 33023-A  (2) directly over the inner race of the bearing.
  10. Position the J 8433-1  (5) center forcing bolt on the J 33023-A  (2) and assemble the 2 through-bolts and the washers through the J 8433-1  (5) slots. Thread them into the J 42428  (3). The thread of the through-bolts should engage the full thickness of the fixture.
  11. Tighten the center J 8433-3  (1) in the J 8433-1  (5) to force the pulley rotor and the bearing assembly onto the compressor housing.

  12. Object Number: 1251988  Size: SH
  13. Install the rotor and the bearing assembly retainer ring using the J 6083  (1).
