With FS-10 Compressor

A/C Clutch, Pulley, And Field Assembly:

REMOVAL

A/C Clutch Hub Retaining Bolt - Removal:

1. Remove the A/C clutch retaining bolt. Use Spanner Wrench T7OP-4067-A.

A/C Clutch Removal:

2. Pull the A/C clutch and the shims from the compressor shaft. If the A/C clutch cannot be pulled from the compressor shaft, screw a 6 mm bolt into the shaft hole of the A/C clutch to force it from the shaft.

A/C Pulley Snap Ring - Removal/Installation:

3. Remove the pulley snap ring.
4. Pull the A/C compressor clutch pulley assembly from the A/C compressor.

INSTALLATION
1. Clean the pulley bearing surface of the compressor head to remove any dirt or corrosion.
2. Install the A/C compressor clutch pulley assembly on the A/C compressor. The bearing is a slip-fit on the compressor head and, if properly aligned, it should slip on easily.
3. Install the pulley snap ring with the bevel side of the snap ring out.
4. Place one nominal thickness spacer shim inside the hub spline opening and slide the A/C clutch on the end of the compressor shaft.
5. Thread a new 6 mm hub retaining bolt into the end of the compressor shaft. Tighten the hub retaining bolt to 11-13 Nm (8-10 ft lb).

CAUTION: Do not use air tools.

A/C Clutch Air Gap Check:

6. Check the air gap between the A/C clutch and the A/C compressor clutch pulley mating surfaces with a feeler gauge.
7. The air gap should be between 0.35-0.85 mm (0.014-0.033 inch).
8. Check the air gap at three locations equally spaced around the A/C compressor clutch pulley.
9. If the air gap is not within 0.35-0.85 mm (0.014-0.038 inch), repeat the above steps with various thickness shims until the air gap is within the specified limits.
10. When installing a new A/C clutch, cycle it ten times at idle to burnish the A/C clutch and prevent slippage.
