THE A/C CLUTCH BROKE AND CUT A LINE FROM THE COMPRESSOR.I REMOVED THE COMPRESSOR AND CLUTCHWITH PLANS TO REPLACE THEM AND THE BROKEN LINE MYSELF. THEN TAKE IT TO A A/c REPAIR SHOP TO HAVE THEM CHARGE THE SYSTEM. THE NEW COMPRESSOR HAS THE PROPER AMOUNT OF OIL IN IT FROM THE FACTORY.MY PROBLEM IS CAN THE "USABLE PARTS" BE FLUSHED/CLEANED WITH THE NEW PARTS INSTALLED?

    A couple things -

    Replace the orifice tube if you haven't already. This catches quite a bit of debris in your system.

    If you have debris in your system, such as in your evaporator or condenser, then you must have the system flushed, or you must replace the components. A third option is to have a filter kit installed - there is a filter that goes in line that traps debris. The system is run, and then this filter is replaced after the initial run...with the theory that it will trap debris on start up.

    Not many shops have an AC flusher, but some do...hopefully your shop does.
