Shaft Key, Clutch Plate/Hub Installation:

Installing Clutch Plate & Hub Assembly:

Install or Connect

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

NOTICE: Do not drive or pound on the clutch hub or shaft. Internal damage to compressor may result.

4. Remove the J 33013-B remover-installer center screw and reverse the body direction on the center screw as shown in the illustration.
5. Install the clutch plate and hub installer J 33013-B with bearing as shown in the illustration.
The body of the J 33013-B installer should be backed off sufficiently to allow the center screw to be threaded onto the end of the compressor shaft.
6. Hold the center screw with a wrench. Tighten the hex portion of the installer 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 0.40-0.50mm (0.015-0.020").
^ 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 assume the position as shown in the illustration and will break the clutch hub.
7. Remove installer J 33013-B, check for proper positioning of the shaft key (even or slightly above the clutch hub). Install the shaft nut. Hold the clutch plate and hub assembly with clutch hub holding tool J 33027-A and using shaft nut socket J 33022, tighten the nut against the crankshaft shoulder to 16.5 N.m (12 lbs.ft.) torque, using a torque wrench.
8. Spin the pulley rotor by hand to see that the rotor Is not rubbing the clutch drive plate.
