A/C Compressor Clutch - Installation






A/C CLUTCH





1. Align the dowel pin on the back of the A/C clutch coil (2) with the hole in the front of the A/C compressor (3) and install the coil onto the compressor.

CAUTION: The snap ring must be fully and properly seated in the groove or it may vibrate out, resulting in a clutch failure and severe damage to the A/C compressor.

2. Using snap ring pliers, install the snap ring (1) that secures the A/C clutch coil (2) to the A/C compressor (3). Be certain that the snap ring is fully and properly seated in the groove.






CAUTION: When installing the pulley and bearing assembly, DO NOT mar the friction surfaces of the pulley or premature failure of the A/C clutch may result.

3. Install the pulley and bearing assembly (2) onto the A/C compressor (3). If necessary, gently tap the pulley onto the compressor using a block of wood placed on the pulley friction surface.
4. Using snap ring pliers, install the snap ring (1) that secures the pulley and bearing assembly to the A/C compressor. Be certain that the snap ring is fully and properly seated in the groove.





5. If the original clutch plate (2) and pulley and bearing assembly are to be reused, reinstall the original shim(s) (3) onto the compressor shaft (1). If a new clutch plate and pulley and bearing assembly are being used, install a trial stack of shims 2.54 mm (0.010 in.) thick onto the compressor shaft.





6. Install the clutch plate (2) onto the A/C compressor (3).
7. Install the compressor shaft bolt (1). Tighten the bolt to 14 Nm (10 ft. lbs.).

NOTE: The shims may compress after tightening the shaft bolt. Check the air gap in four or more places to verify the air gap is correct. Spin the pulley before performing a final check of the air gap.

8. With the clutch plate assembled tight against the shim(s), measure the air gap between the clutch plate and the pulley and bearing assembly. The air gap should be between 0.20 - 0.45 mm (0.007 - 0.018 in.). If the air gap is not between specifications, add or subtract shims as needed until the correct air gap is obtained.
9. Install the A/C compressor A/C Compressor - Installation.
