With A-6 Compressor

A-6 Compressor Component View:

When servicing the Harrison A-6 compressor, prevent dirt or foreign material from getting on or into the compressor parts and system during disassembly or reassembly.

Keep tools and work area clean. Clean the compressor exterior before disassembly. Clean parts with trichloroethane, naptha or Stoddard solvent, kerosene or equivalent. Dry with air.

Use a non-lint producing type cloth to clean each part.

Although certain service operations can be performed without removing the compressor from the vehicle, the operations described here are based on bench repair with the compressor removed from the vehicle. They have been prepared in sequence in order of accessibility of the components.

For compressor removal and installation, refer to the proper truck service manual.

Do not kink or place excessive tension on lines or hoses.

After removing the compressor from the vehicle, drain and measure the refrigerant oil. Add new 525 viscosity refrigerant oil after repair.
