NOTE: Pulley Puller 412-D008 (D81P-19703-B) or equivalent may be used as an alternative to Differential Side Bearing Puller 205-116 (T77F-4220-B1).

6. Tighten the puller forcing screw to pull the A/C clutch field coil from the A/C compressor head.

INSTALLATION

CAUTION: Do not use air tools. The A/C clutch field coil can be easily damaged.

1. Clean the coil mounting surface on the front head to remove any dirt or corrosion.
2. With the A/C compressor in a vertical position (nose up), place the A/C clutch field coil in position on the compressor front head. Make sure the A/C clutch field coil electrical connector is positioned correctly as noted during removal.
3. Place the Coil Pressing Tool 412-065 (T89P-19623-EH) with Field Coil Replacer 412-078 (T91L-19623-CH) in position over the compressor nose and to the inner radius of the A/C clutch field coil.
4. Position 2-Jaw Puller 205-D026 (D80L-1002-L) or equivalent on the A/C compressor and coil pressing tool. The jaws of the puller should be firmly engaged with the rear side of the A/C compressor front mounts. The forcing screw must be piloted on the center mark of the pressing tool.

A/C Coil Pressing Tool - Installation:

5. Tighten the forcing screw with a hand wrench until the A/C clutch field coil is pressed on the A/C compressor front head. Check to make sure that the A/C clutch field coil bottoms against the head at all points around the coil outer diameter.
6. Install the A/C clutch pulley and A/C clutch on the A/C compressor.
7. Check and adjust A/C clutch air gap.
8. Install the A/C compressor on the vehicle.
