Remove or Disconnect

Tools Required:
J 6083 External Snap Ring Pliers
J 29886 Driver Handle
J 9398-A Pulley Bearing Remover
J 33020 Pulley Puller
J 33023-A Puller Pilot

1. Clutch plate and hub assembly (2).

Removing The Rotor & Bearing Retaining Ring:

2. Rotor and bearing assembly retaining ring (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 Pulley 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.
^ Remove the forcing screw from J 33020 and with the puller tangs still in place in the pulley slots, turn the assembly upside down onto a flat surface.
^ 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.

Tools Required:

J 6083 Snap Ring Pliers
J 8433-1 Puller Bar
J 9481-A Pulley Bearing Installer
J 33017 Pulley and Bearing Assembly Installer
J 33019 Bearing Staking Tool (with staking pin and retaining band)
J 33023-A Puller Pilot
J 33026 Compressor Holding Fixture
J 21352-A Compressor Support Block

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

NOTICE: Do not support the rotor by resting the pulley rim on a fiat surface during bearing installation or the rotor lace 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 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.

Bearing Stake Locations:

- Stake 3 places 120° 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 the compressor holding fixture.

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.

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