SPECIAL SERVICE TOOL(S) REQUIRED
Description Tool Number
Spanner Wrench T70P-4067-A

 

Removal

  1. Remove the A/C clutch retaining bolt. Use Spanner Wrench T70P-4067-A.



  1. Pull A/C clutch and A/C compressor clutch shims from A/C compressor shaft. If A/C clutch cannot be pulled from A/C compressor shaft, screw a 6mm bolt into the shaft hole of the A/C clutch to force the A/C clutch from the shaft.



  1. Remove A/C compressor clutch pulley retaining snap ring.



  1. Pull the A/C compressor clutch pulley (2E884) assembly from A/C compressor (19703) .
 

Installation

  1. Clean A/C compressor clutch pulley bearing surface of A/C compressor head to remove any dirt or corrosion.
  1. Install A/C compressor clutch pulley assembly on A/C compressor . The bearing is a slip-fit on the A/C compressor head and, if properly aligned, it should slip on easily.
  1. Install A/C compressor clutch pulley retaining snap ring with bevel side of snap ring out.
  1. Place one nominal thickness spacer A/C compressor clutch shim inside the A/C clutch spline opening and slide the A/C clutch on the end of the A/C compressor shaft.
  1. Thread a new 6mm A/C clutch retaining bolt into end of A/C compressor shaft. Tighten A/C clutch retaining bolt to 11-13 Nm (8-10 lb-ft). DO NOT USE AIR TOOLS.
  1. Check A/C clutch air gap between A/C clutch and A/C clutch pulley mating surfaces with a feeler gauge. The air gap should be between 0.35 and 0.85mm (0.014 and 0.033 inch). Check at three locations equally spaced around the A/C compressor clutch pulley .



  1. If A/C clutch air gap is not within 0.35 to 0.85mm (0.014 to 0.033 inch), repeat Steps 4 through 6 with various thickness A/C compressor clutch shims until air gap is within specified limits.
  1. When installing a new A/C clutch , cycle it ten times at idle to burnish the A/C clutch and prevent slippage.

Removal

 CAUTION: Do not use air tools.

  1. Remove the A/C compressor from the vehicle. Refer to Section 12-03A.
  1. Remove the A/C clutch and A/C compressor clutch pulley as outlined.
  1. Install Shaft Seal Protector for Coil Removal T89P-19623-CH on the nose opening of the A/C compressor .
  1. Install Differential Side Bearing Puller T77F-4220-B1 on the A/C 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 compressor clutch field coil .
  1. Tighten the puller forcing screw to pull the A/C compressor clutch field coil from the A/C compressor head.
 

Installation

 CAUTION: Do not use air tools.

  1. Clean the A/C compressor clutch field coil mounting surface on the front head to remove any dirt or corrosion.
  1. With the A/C compressor in a vertical position (nose up), place the A/C compressor clutch field coil in position on the A/C compressor front head. Make sure the A/C compressor clutch field coil electrical connector is correctly positioned.
  1. Place the Coil Pressing Tool T89P-19623-EH in position over the A/C compressor nose and to the inner radius of the A/C compressor clutch field coil .
  1. Position 2-Jaw Puller D80L-1002-L or equivalent on the A/C compressor and the Coil Pressing Tool T89P-19623-EH. 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 field coil replacer tool.



  1. Tighten the forcing screw with a hand wrench until the A/C compressor clutch field coil is pressed on the A/C compressor front head. Check to make sure that the A/C compressor clutch field coil bottoms against the head at all points around the A/C compressor clutch field coil outer diameter.
  1. Install the A/C compressor clutch pulley and A/C clutch on the A/C compressor as outlined. Adjust the air gap, as necessary.
  1. Install the A/C compressor as outlined.
