Clutch Rotor and/or Bearing
Remove or Disconnect1. Remove the clutch plate and hub assembly as described previously.
Removing Pulley Rotor & Bearing Assembly Retaining Ring:
2. Remove rotor and bearing assembly retaining ring. using snap ring pliers J 6083.
Installing Pulley Rotor/Bearing Puller Guide:
Removing Pulley Rotor And Bearing Assembly:
3. Install pulley rotor and bearing puller guide J 33023-A to the front head and install J 33020 pulley rotor and bearing puller down into the inner circle of slots in the rotor. Turn the J 33020 puller clockwise in the slots to engage the puller tangs with the segments between the slots in the rotor.
4. Hold the J 33020 puller in place and tighten the puller screw against the puller guide to remove the pulley rotor and bearing assembly.
5. To prevent damage to the pulley rotor during bearing removal the rotor hub must be properly supported.
Pulley Rotor Bearing Removal:
Remove the forcing screw from J 33020 puller and, with the puller tangs still engaged in the rotor slots, invert the assembly onto a solid flat surface or blocks as shown in the illustration.
6. Drive the bearing out of the rotor hub with rotor bearing remover J 9398-A and J 29886 universal handle.
It is not necessary to remove the staking in front of the bearing to remove the bearing, however , 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.
Install or Connect
Installing Pulley Rotor Bearing:
1. Place the pulley rotor on the J 21352-A support block to fully support the rotor hub during bearing installation.
NOTICE: Do Not support the rotor by resting the pulley rim on a flat surface during the bearing installation or the rotor face will be bent.
2. Align the new bearing squarely with the hub bore and using puller and bearing installer J 9481-A with universal handle 1 29886, drive the bearing fully into the hub. The installer will apply force to the outer race of the bearing if used as shown.
Staking Bearing In Rotor Hub Bore:
3. Place bearing staking guide J 33019-1 and bearing staking pin 133019 in the hub bore as shown in Figure 13. Shift the rotor and bearing assembly on the J 21352-A support block to give full support of the hub under the staking pin location. A heavy-duty rubber band may be used to hold the stake pin in the guide, and the stake pin should be properly positioned in the guide after each impact on the pin
4. Using care to prevent personal injury, strike the staking pin with a hammer until a metal stake, similar to the original, is formed down to but not touching the bearing.
Bearing Staked In Place:
The stake metal should not contact the outer face of the bearing to prevent the possibility of distorting the outer race. Stake three (3) places 120° apart as shown in the illustration.
Installing Pulley Rotor And Bearing Assembly:
5. With the compressor mounted to the J 34992 holding fixture, position the rotor and bearing assembly on the front head.
6. Position the J 33017 pulley rotor and bearing installer and J 33023-A puller pilot directly over the inner race of the bearing.
7. Position puller crossbar J 8433-1 on the puller pilot J 33023-A and assemble the two J 34992-2 through bolts and washers through the puller bar slots and thread them into the J 34992 holding fixture. The thread of the through bolts should engage the full thickness of the holding fixture.
8. Tighten the center screw in the J 8433-1 puller crossbar to force the pulley rotor and bearing assembly onto the compressor front head. Should the J 33017 pulley rotor and bearing installer slip off direct in-line contact with the inner face of the bearing, loosen the J 8433-3 center forcing screw and realign the installer and pilot so that the J 33017 installer will properly clear the front head.
9. Install rotor and bearing assembly retainer ring, using snap ring pliers J 6083.
10. Reinstall clutch plate and hub assembly as described previously.
