With 10P15F A/C Compressor

A/C Compressor Clutch Assembly:

REMOVAL

A/C Clutch Hub Nut - Removal:

1. Remove the clutch hub retaining nut. Use Spanner Wrench T81P-19623-MH or equivalent, if necessary.

A/C Clutch Hub - Removal:

2. Remove the clutch hub and shims from the compressor shaft with the Hub Driven Plate Remover T80L-19703-B or equivalent. Hold the tool with a 1-inch wrench and tighten the bolt with a 1/2-inch wrench to pull the hub from the compressor shaft.

A/C Pulley Snap Ring - Removal:

3. Remove the clutch pulley retaining snap ring.

Clutch Pulley Removal:

4. Pull the pulley and bearing assembly from the compressor. If the pulley and bearing assembly cannot be removed by hand, use the Shaft Protector T80L-19703-G and the Pulley Puller D81P-19703-B or T71P-19703-B or equivalent to remove the pulley.

INSTALLATION
1. Clean the pulley bearing surface of the compressor head to remove any dirt or corrosion.

A/C Clutch Pulley - Installation:

2. Install the pulley and bearing on the compressor. The bearing is a slip fit on the compressor head and, if properly aligned, it should slip on the compressor head. If difficulty is encountered installing the pulley, gently tap the pulley on the compressor using the Pulley and Bearing Tool T80L-19703-J. Ensure the pulley bearing is aligned with the compressor head.
3. Install the pulley retaining snap ring with the bevel side of the snap ring out.

A/C Clutch Hub - Installation:

4. Install the clutch hub on the compressor shaft using the two thickest shims of the shim pack between the clutch hub and the end of the compressor shaft. Ensure the shaft key is aligned with the keyway of the clutch hub. Use the Hub Driven Plate Replacer T80L-19703-F or equivalent to press the hub on the compressor shaft, if necessary.

CAUTION: 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 compressor shaft.

5. Install the hub lock washer and the retaining nut on the compressor shaft. Tighten the nut to 13-20 Nm (10-14 ft lb).

CAUTION: Do not use air tools.

A/C Clutch Air Gap Check:

6. Check the air gap between the hub and the mating pulley surface in three locations equally spaced around the pulley. Record the air gap readings.
7. Rotate the compressor pulley one-half turn (180 degrees) and again check the air gap in three equally spaced locations. The smallest air gap must be within 0.53-0.91 mm (0.021-0.036 inch). Add or remove shins between the hub and the compressor shaft end as necessary until the smallest air gap is within specification.
