Preliminary Information

HR6-HE Compressor Components - Disassembly:

Shaft Key, Clutch Plate/Hub Installation:

THE FOLLOWING OPERATIONS TO THE HR6-HE COMPRESSOR CLUTCH PLATE AND HUB, ROTOR AND BEARING, AND COIL ARE COVERED AS "MINOR" BECAUSE THEY MAY BE PERFORMED WITHOUT FIRST RECOVERING REFRIGERANT FROM THE SYSTEM OR REMOVING THE COMPRESSOR FROM THE VEHICLE.

The Compressor Shaft Seal assembly, control switches, and Pressure Relief Valve may also be serviced WITHOUT REMOVING THE compressor from the vehicle but these operations are covered later in this section as MAJOR REPAIR PROCEDURES because the system must be reclaimed, evacuated and recharged to complete service.

Illustrations used in describing these operations show the compressor removed from the vehicle only to more clearly illustrate the various operations.

When servicing the compressor, remove only the parts that preliminary diagnosis shows are in need of service.

Removal and installation of external compressor parts, and disassembly and assembly of internal parts, must be performed on a clean workbench. The work area, tools and parts must be kept clean at all times.
