Girlfriend '94 T/A has a dead compressor clutch - it won't engage. I believe its an electrical problem with the magnetic ring within the clutch. My buddy had a spare compressor and I plugged it in and the clutch enagegs, so all the electrical for the car is good and in working order. I was just wondering if anyone has ALLDATA or Mitchell or something that can post the procedure to swap out the clutches and the tools required. I dont wnat to have to discharge the system. Thanks.

Clamp the holding fixture J 33020 in a vise and attach compressor to holding fixture with thumb screws J 33026-1.
With center screw forcing tip in place to thrust against the end of the shaft, thread the Clutch Plate and Hub Assembly installer-Remover J 33013-B into the hub. Hold the body of the remover with a wrench and turn the center screw into the remover body to remove the clutch plate and hub assembly. NOTICE: Do not drive or pound on the clutch hub or shaft. Internal damage to the compressor may result. The forcing tip on J 33013-B remover-installer screw must be flat or the end of the shaft/axial plate assembly will be damaged.
Remove the shaft key and retain for assembly.

Install the shaft key into the hub key groove. Allow the key to project approximately 3.2mm (1/8") out of the keyway. The shaft key is curved slightly to provide an interferance fit in the hub key groove.
Be sure the frictional surface of the clutch plate and the clutch rotor are clean before installing the clutch plate and hub assemblies.
Align the shaft key with the shaft keyway and place the clutch plate and the hub assembly onto the compressor

Remove the forcing tip on J 33013-B clutch plate and hub assembly installer-remover center screw and reverse the body direction on the center screw.

Install the clutch plate and hub installer-remover J 33013-B with bearing. The body of the J 33013-B installer-remover should be backed off sufficiently to allow the center screw to be threaded onto the end of the compressor shaft.
Hold the center screw with a wrench. Tighten the hex portion of the installer-remover J 33013-B body to press the hub onto the shaft. Tighten the body several turns, remove the installer and check to see that the shaft key is still in place in the keyway before installing the clutch plate and hub assembly to its final position . The air gap between frictional surfaces of the clutch plate and clutch rotor should be 0.50-0.76mm (0.020-0.030"). NOTICE: If the center screw is threaded fully onto the end of the compressor shaft, or if the body of the installer is held and the center screw is rotated, the key will wedge and will break the clutch hub.
Remove installer J 33013-B, check for proper positioning of the shaft key (even or slightly above the clutch hub).
Spin the pulley rotor by hand to see that the rotor is not rubbing the clutch drive plate.

 

Remove the clutch plate and hub assembly.

Remove rotor and bearing assembly retaining ring, using snap ring pliers J 6083.

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 in the rotor.
Hold the J 33020 puller in place and tighten the puller screw against the puller guide to remove the pulley rotor and bearing assembly.
To prevent damage to the pulley rotor during bearing removal the rotor hub must be properly supported.

Refer to pic 4

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.

Drive the bearing out of the rotor hub with rotor bearing remover J 9398A and J 29886 universal handle. NOTICE: It is not necessary to remove the staking in front of the bearing to remove the bearing, however, it will he 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.

Refer to pic 5

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.
Align the new bearing squarely with the hub bore and using puller and bearing installer J 9481-A with universal handle J 29886 drive the bearing fully into the hub. The installer will apply force to the outer race of the bearing.

Refer to pic 6

Place bearing staking guide J 33019-1 and bearing staking pin J 33019-2 in the hub bore. 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.
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.

Refer to pic 7

Noisy bearing operation and reduced bearing life may result if outer bearing race is deformed while staking, the stake metal should not contact the outer race of the bearing. Stake three places 120°apart.

Refer to pic 8

With the compressor mounted to the J 33026 holding fixture, position the rotor and bearing assembly on the front head.
Position the J 33017 pulley, rotor, and bearing installer and J 33023-A puller pilot directly over the inner race of the bearing.
Position puller crossbar J 8433-1 on the puller pilot J 33023-A and assemble the two J 33026-2 through bolts and washers through the puller bar slots and thread them into the J 33026 holding fixture. The thread of the through bolts should engage the full thickness of the holding fixture.
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 race of the bearing, loosen the J 8433-1 center forcing screw and realign the installer and pilot so that the J 33017 installer will properly clear the front head.
Install rotor and bearing assembly retainer ring, using snap ring pliers J 6083.
Reinstall clutch plate and hub assembly.

Hopefully that is what you are needing. I know nothing about A/C repair so I can not answer any questions or give any advice on this repair. Good luck.

Bummer. Sounds like I have to pull the damn compressor out which means discharge anyway.
