    Caution: Do not support the rotor/hub assembly by resting the compressor pulley on a flat surface. Always support the rotor/hub assembly by securely resting the hub on a stable flat surface. The compressor pulley face could be damaged.

  10. Remove the puller bolt from the J 33020  (3). With the puller tangs still engaged in the rotor slots, invert the assembly onto a solid flat surface or blocks.
  11. Caution: When removing the bearing, it is not necessary to remove the staking in front of the bearing. 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.

  12. Drive the bearing out of the rotor hub with the J 9398-A  (2) and the J 8092  (1).
