  Q:

  How to Service and Repair an A/C Compressor Clutch on Chrysler Prowler?

  A:

  Take the compressor out of the vehicle and, using a specially designed oil filter removal tool, remove the bolt nearby the compressor clutch. Use a plastic hammer to hit the clutch plate which should be taken off along with any shims, while steering clear of using screwdrivers between the clutch plate assembly and pulley. Then, take out the pulley retaining snap ring with Snap Ring Pliers (C-4574) and bring the pulley assembly away from the compressor. First remove the screw holding in the coil wire bracket/ground clip and then the wire harness, next take out the snap ring to release the field coil from the compressor housing. Check the clutch pulley and front plate for wear and damage; replace them if there is too much sign of wear or scoring. Should you discover oil around the friction surfaces, carefully look at the nose area of the shaft. If the felt in the front cover is wet, replace the seal. In addition, make sure the bearing is even and not greasy in places and get a new one if needed. Always check if there are signs of deep line or wear on both the rotor-pulley and armature plate and make sure there is no grease around these areas. As you fit the pin in the back of the field coil with its matching hole in the compressor end housing, position all the wires out of the way and put the screw through the diode and coil wire bracket to secure it. Use C-4574 Snap Ring Pliers to fit the retaining snap ring with the bevel side facing outward and the eyelets correctly in place. Place the pulley assembly around the compressor shaft, striking gently if it sticks and use the retaining snap ring to hold it in place (again, with the bevel side facing away from the block). If using the original front plate and pulley assembly, try fitting the old shim; else, place two new shims, 2.54 mm (0.10 in.) each, on the shaft against the shoulder. For new front plates and pulley assemblies, position a dial indicator so that there is a gap of 0.35 to 0.65 mm (0.014 to 0.026 in.) between them and add or remove shims as needed to maintain this gap. Once the barrel bolt is in, tighten the compressor shaft bolt to 17.5 ± 2 Nm (155 ± 20 in. lbs.) and make sure the air gap is correct in different spots after installing the bolt. Cycle the A/C clutch twenty times (10 seconds ON, 10 seconds OFF) with the car in A/C mode, the engine RPM between 1500 and 2000 and the blower set to high speed to bring in the friction surfaces and improve the clutch's strength.
