NOTE: The A/C clutch field coil is pressed on the front head of the compressor. Special service tools are required to remove and install the A/C clutch field coil.

SPECIAL SERVICE TOOL(S) REQUIRED

Removal

1. Remove the A/C compressor from the vehicle following the recommended service procedure.

2. Remove the clutch hub and pulley as described in this section. Note the location of coil electrical connection for proper orientation during compressor clutch coil installation.

3. Install Shaft Protector for Coil Remover T89P-19623-FH on the nose opening of the A/C compressor.

4. Install a Differential Side Bearing Puller T77F-4220-B1 or equivalent on the compressor. Place the tip of the puller forcing screw in the center pilot of the shaft protector and the jaws of the puller around the back edge of the A/C clutch field coil.







5. Tighten the puller forcing screw to pull the A/C clutch field coil from the compressor head. DO NOT USE AIR TOOLS.


Installation

1. Clean the 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 electrical connector is positioned correctly.

3. Place the Coil Pressing Tool T89P-19623-EH and Field Coil Replacer 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 Tool D8OL-1002-L or equivalent on the compressor and the Coil pressing tool. The jaws of the puller should be firmly engaged with the rear side of the compressor front mounts. The forcing screw must be piloted on the center mark of the pressing tool.








5. Tighten the forcing screw with a hand wrench until the A/C clutch field coil is pressed on the compressor front head. DO NOT USE AIR TOOLS. Check to make sure that the A/C clutch field coil bottoms against the head at all points around the outer diameter.

6. Install the clutch pulley and hub on the A/C compressor as outlined. Adjust the air gap, as necessary.

7. Install the compressor on the vehicle following the recommended procedure.
