Hello and welcome to just answer Dodge. Here is the procedure for doing this. The manual talks about some special tools, but you can probably get by with out them. However you will need a couple of snap ring pliers.
Hope this information helps, and let me know if you need more assistance with this.
The refrigerant system can remain fully-charged during compressor clutch, pulley, or coil replacement. The compressor clutch can be serviced in the vehicle.
NOTE: The air gap is determined by the spacer shims. When installing an original, or a new clutch assembly, try the original shims first. When installing a new clutch onto a compressor that previously did not have a clutch, use 0.040, 0.020, and 0.005 shims from the clutch hardware package that is provided with the new clutch.
After a new compressor clutch has been installed, cycle the compressor clutch approximately 20 times (5 seconds on, then 5 seconds off) During this procedure, set the heater-A/C controls to the A/C (Recirc) mode, the blower motor switch in the highest speed position, and the engine speed at 1500 - 2000 rpm. This procedure (burnishing) will seat the opposing friction surfaces and provide a higher compressor clutch torque capability.
