Clutch Hub Installation
4. Using the two thickest shims between the hub and the end of the compressor shaft align the shaft key with the keyway in the hub and install the hub
on the compressor shaft. Use Tool T80L-19703-F or equivalent to press the hub on the shaft if necessary. Do not attempt to drive the hub on the
compressor shaft as damage to the compressor will result. Use only the specified tool if the hub will not easily slide on the shaft.
5. Install the hub retaining nut on the compressor shaft and tighten the hub retaining nut to 13-23 Nm (10-14 ft lb).
Checking Clutch Air Gap
6. Check and record the air gap between the hub and the mating pulley surfaces in three locations equally spaced around the pulley.
7. Rotate the compressor or pulley 1/2 turn (180 degrees) and again check the air gap in three equally spaced locations. The smallest air gap must be
within 0.021-0.036 inch. Add or remove shims as necessary until the smallest air gap is within specification.
