Installation

NOTE: The A/C clutch components should be reused unless obvious signs of damage are found. If excessive grooving is found, a new A/C clutch disc and hub and a new A/C compressor pulley must be installed together. Otherwise, each component may be installed individually where needed.

1. Visually inspect the A/C clutch disc and hub, A/C compressor pulley and A/C clutch field coil for damage.
- Inspect for physical damage, including cracked or melted components or discoloration due to excessive heat.
- Inspect for excessive wear, including grooving in the A/C clutch disc and hub or A/C compressor pulley that is more than fingernail depth.
- Inspect for roughness in the A/C compressor pulley bearing.

2. Clean the A/C clutch field coil and pulley mounting surfaces.
3. Install the A/C clutch field coil.
4. Install the A/C clutch field coil snap ring with the bevel side up.
5. Install the A/C clutch field coil electrical connector bracket screw.

6. CAUTION: To prevent A/C compressor pulley damage, apply pressure to the inner bearing race only, or the inner and outer bearing races simultaneously.

NOTE: The A/C compressor pulley is a tight fit on the A/C compressor. It must be correctly aligned during installation.
