1. Clutch plate and hub assembly (2).

Removing The Pulley Rotor & Bearing Retaining Ring:

2. Pulley bearing retainer (3) using J 6083.

3. Pulley (5).

Installing The Puller Pilot & Pulley Rotor Slot Location:

^ Install J 33023-A to the front head.

Installing J-33020 In The Pulley Rotor Slots:

^ Install J 33020 tangs into the inner circle of slots in the pulley (5) contact surface. Rotate J 33020 clockwise so the tangs will lock into the segments between the slots.

Removing The Puller Bearing:

^ Hold J 33020 in place and tighten the puller screw against J 33023-A puller pilot to remove the pulley (5).

4. Pulley bearing (4) from the pulley (5) using J 9398-A and J 29886.
^ When removing the old pulley bearing (5) allow the staking to remain, then file away the old staked metal for proper fit when installing a new bearing (5) in the pulley bore.

1. Pulley (5) on J 21352-A.

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

Installing The Pulley Rotor Bearing:

2. Pulley bearing (4) into the hub using J 29886, J 9481-A and J 21352-A.

Staking The Pulley Bearing In The Rotor Bore:

^ J 33019-1 in the pulley bore.
^ Seat the pulley and bearing assembly on J 21352-A to support to the hub under the staking pin location.
^ Strike the staking pin with a hammer until a metal stake, similar to the original, is formed down to, but not touching the bearing.
- Position the stake pin after striking.
- The staked metal should not contact the outer race of the bearing to prevent the possibility of bending the outer race.

Staking Locations:

- Stake 3 places 120 degrees apart.

3. Pulley (5) on the front head.

Installing The Pulley Bearing Assembly:

^ Position J 33017 and J 33023-A over the inner race of the bearing.
^ Position J 8433-1 on J 33023-A and assemble the through bolts and washers through the puller bar slots and thread them into J 33026.
- The thread of the through bolts should engage the full thickness of J 33026.
^ Tighten the center screw in J 8433-1 to force the pulley and bearing assembly onto the compressor front head (11).
- Should J 33017 become misaligned with the inner race of the bearing, back off J 8433-1 and relocate center, then continue installation.

Removing The Pulley Rotor & Bearing Retaining Ring:

4. Pulley bearing retainer (3) using J 6083.
5. Clutch plate and hub assembly (2).
