Installing Shaft Key

The shaft key is curved slightly to provide an interference lit in the shaft key groove of the hub.
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 Hub assembly onto the compressor shaft.
NOTICE: To avoid internal damage to the compressor, do not drive or pound on the clutch hub or shaft.

0.5-7.6mm (0.020-0.030") air gap between the frictional surfaces of the clutch plate and clutch rotor.
