Special Tools Required

6071725.png A/C Compressor Kit 07AAF-000A150
1. A/C Compressor Pressure Plate - Remove
1.
Remove the center bolt (A) while holding the pressure plate (B) with the A/C clutch holder (C).
2.
Remove the pressure plate (A) and the shim(s) (B).
NOTE:
Do not pry on the pressure plate with screwdrivers or similar tools. Prying damages the pressure plate and the pulley.
Inspect the pressure plate and pulley friction surfaces for wear. If there is excessive wear, roughness, or scoring, replace the clutch set.
If compressor oil is found, replace the A/C compressor.
A leaking compressor front shaft seal should be inspected at this step.

2. A/C Compressor Pulley - Remove
1.
Remove the snap ring (A) with the snap ring pliers.
2.
Remove the pulley (A).
NOTE:
Do not hammer or pry on the pulley to remove it. Using a hammer damages the A/C compressor. If the pulley is difficult to remove, use a commercially available pulley removing tool. Make sure the jaws of the pulling tool engage the back face of the pulley, not the pulley grooves.
Be careful not to damage the pulley or the A/C compressor.

3. A/C Compressor Field Coil - Remove
1.
Remove the field coil ground terminal (A), the harness clip (B), and the bracket (C).
2.
Remove the snap ring (D) with the snap ring pliers.
3.
Remove the field coil (E). Be careful not to damage the field coil or the A/C compressor.
NOTE: Inspect the friction surfaces and the compressor shaft hub for excess oil. If excess oil is present, and it is not from the engine or power steering system, then the compressor shaft seal is leaking. Replace the A/C compressor.


NOTE:
When replacing the field coil, check that the new coil has the correct resistance.
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.
If the clutch surface is oil soaked, check the compressor front seal for leakage. Installing a new clutch assembly on a leaking compressor will damage the new clutch assembly friction surfaces.
Clean the 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 pulley turns smoothly after it's reassembled.
Route and clamp the wires properly to prevent damage by the pulley.
After reinstallation, cycle the A/C compressor clutch approximately 20 times by running the engine at 1,500?2,000 rpm and setting the A/C system to MAX COOL. This procedure seats the clutch sliding surfaces, and increases clutch torque capacity.

1. A/C Compressor Field Coil - Install
1.
Install the field coil (A).
NOTE: Be careful not to damage the field coil and A/C compressor.
2.
Install the snap ring (B) with the snap ring pliers.
3.
Install the bracket (C), the harness clip (D), and the field coil ground terminal (E).

2. A/C Compressor Pulley - Install
1.
Install the pulley (A).
NOTE: Be careful not to damage the pulley or the A/C compressor.
2.
Install the snap ring (A) with the snap ring pliers.

3. A/C Compressor Pressure Plate - Install
1.
Install the pressure plate (A) and the shim(s) (B).
NOTE:
The shims are available in three thicknesses: 0.1 mm, 0.3 mm, and 0.5 mm.
When removing the pressure plate, place a trial stack of shims, 1mm total thickness, on the A/C compressor shaft. Install the pressure plate, and check its clearance. If the clearance is not with specification, add or subtract shims as needed.
2.
Install the center bolt (A) while holding the pressure plate (B) with the A/C clutch holder (C).
If the clutch needs adjustment, increase or decrease the number and thickness of shims as necessary, then reinstall the pressure plate, and recheck its clearance.
