A/C Compressor Clutch Overhaul

Special Tools Required 

A/C Compressor Kit 07AAF-000A150

1. Remove the center nut while holding the armature plate (A) with the A/C clutch holder (B).

2. Remove the armature plate (A) and shim(s) (B), taking care not to lose the shim(s). If the clutch needs adjustment, increase or decrease the number and thickness of shims as necessary, then reinstall the armature plate, and recheck its clearance (see A/C COMPRESSOR CLUTCH CHECK  ).
   NOTE:

   • The shims are available in four thicknesses: 0.1 mm, 0.2 mm, 0.4 mm, and 0.5 mm.
   • Do not pry on the armature plate with screwdrivers or similar tools. Prying damages the armature plate and the pulley.
   • When replacing the clutch set, place a trial stack of shims, 1 mm total thickness, on the A/C compressor shaft. Install the armature plate, and check its clearance (see A/C COMPRESSOR CLUTCH CHECK  ). If the clearance is not within specification, add or subtract shims as needed.

3. If you are replacing the field coil, remove the snap ring (A) with snap ring pliers, then remove the rotor pulley (B). Be careful not to damage the rotor pulley and A/C compressor.

4. Remove the bolt and holder (A), then disconnect the field coil connector (B). Remove the snap ring (C) with snap ring pliers, then remove the field coil (D). Be careful not to damage the field coil and A/C compressor.

5. Reassemble the clutch in the reverse order of disassembly, and note these items:
   • When replacing the field coil, check that the new coil has the correct resistance (see step  7 on ).
   • Install the field coil with the wire side facing down, and align the boss on the field coil with the hole in the A/C compressor.
   • Clean the rotor pulley and the A/C compressor friction surfaces with contact cleaner or other non-petroleum solvent.
   • Install new snap rings, note the installation direction, and make sure they are fully seated in the grooves.
   • Make sure that the rotor pulley turns smoothly after it's reassembled.
   • Route and clamp the wires properly to prevent damage by the rotor pulley.
6. After reinstallation, cycle the A/C clutch approximately 20 times by running the engine at 1, 500-2, 000 RPM and setting the A/C system to MAX A/C mode. This procedure seats the clutch friction surfaces, and increases clutch torque capacity.
