    To install:


    NOTE
    If installing a new A/C compressor, 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/C compressor pulley must be installed together. Otherwise, each component can 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.
      WARNING
      Do not use air tools. Damage to the A/C clutch field coil or A/C compressor may result.



      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.
