Pulley and Bearing Assembly

Compressor Components:

Remove or Disconnect

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

1. Clutch plate and hub assembly (22).

Removing The Pulley Rotor & Bearing Assembly Retaining Ring:

2. Pulley bearing retainer (24) using J 6083.
3. Pulley (26).

Installing The Pulley Rotor & Bearing Puller Guide:

^ Install J 33023-A to the front head.

Removing The Pulley Rotor & Bearing Assembly:

^ Install J 33020 tangs into the inner circle of slots in the pulley (26) contact surface. Rotate J 33020 clockwise so the tangs will lock into the segments between the slots.
^ Hold J 33020 in place and tighten the puller screw against J 33023-A puller pilot to remove the pulley (26).

Removing The Bearing From The Pulley Rotor Assembly:

4. Pulley bearing (25) from the pulley (26) 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 (25) 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 Puller Bar
J 9481-A Pulley Bearing Installer
J 21352-A Support Block
J 29886 Threaded Driver Handle
J 33017 Pulley and Bearing Assembly Installer
J 33019 Bearing Staking Tool (with staking pin and retaining band)
J 33023-A Puller Pilot
J 34992 Compressor Holding Fixture

Installing The Pulley Rotor Bearing:

1. Pulley (26) 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.

2. Pulley bearing (25) into the hub using J 29886, J 9481-A and J. th21352-A.
^ J 33019 into the pulley bore.

Staking The Pulley Bearing 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 degrees apart.
3. Pulley (26) 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 34992.
- 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 (33).
- If 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 (24) using J 6083.
