Installation

Clutch Pulley Installation:

1. Clean pulley bearing surface of compressor.
2. Install pulley and bearing on compressor. Bearing should be a slip fit onto compressor head. If difficulty is encountered installing pulley, gently tap pulley on compressor using tool T80L-19703-J or equivalent, Fig. 5. Be sure pulley bearing is aligned with compressor head.
3. Install pulley retaining snap ring with bevel side out.

Fig. 6 Clutch hub installation:

4. Install clutch hub on compressor shaft using new shims between clutch hub and end of shaft. Be sure shaft key is aligned with keyway in clutch hub. Do not attempt to drive hub on compressor shaft as damage to compressor will result. Use tool T80L-19703-F or equivalent if hub will not easily slide on compressor shaft, Fig. 6.
5. Install hub retaining nut on compressor shaft and torque to 10-14 ft. lbs.

Fig. 7 Checking clutch air gap:

6. Check clutch air gap between hub and pulley mating surface in three locations equally spaced, Fig. 7. Then rotate pulley one-half turn and check air gap again. The smallest air gap must be within specification. Add or remove shims until desired limit is attained.
