  1. Install clutch coil and clutch coil snap ring. Install clutch coil wire harness to compressor housing. Align pulley and bearing assembly on front compressor housing hub.
  2. Install pulley installer handle and driver into pulley assembly bearing cavity. Ensure outer edge of driver rests firmly on inner race of bearing. Using hammer, install pulley and bearing assembly. While tapping on handle, guide pulley and bearing assembly to prevent binding. Ensure pulley assembly bottoms against compressor housing.
  3. Install internal bearing and external front housing snap rings. Install original shim(s) and compressor shaft key. Using a hammer and shaft protector, install clutch plate on compressor shaft. Ensure clutch plate bottoms out on clutch shims. Replace compressor shaft nut and tighten compressor shaft nut to 25-30 ft. lbs. (34-41 N.m).
  4. Measure air gap between clutch plate and pulley assembly in 3 locations spaced equally around pulley. Rotate clutch pulley 180 degrees and check air gap as specified. Air gap should be 0.016-0.031" (0.41-0.79 mm). If air gap is not within specification, adjust shim thickness as necessary. To complete installation, reverse removal procedure. Evacuate, charge, and leak test A/C system.
