Preliminary Information

Figure 2 - Compressor Components - View:

THE FOLLOWING OPERATIONS TO THE COMPRESSOR CLUTCH PLATE AND HUB, ROTOR AND BEARING, AND COIL & PULLEY RIM ARE COVERED AS "MINOR" BECAUSE THEY MAY BE PERFORMED WITHOUT FIRST PURGING THE SYSTEM OR REMOVING THE COMPRESSOR FROM THE VEHICLE.

Two types of drive Systems are used on the Compressor: V-groove type and poly-groove type. The drive system affects only minor repair procedures and is so noted where required. Major repair procedures are not affected by the type of drive system.

The Compressor Shaft Seal assembly, 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 refrigerant 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 necessary components that preliminary diagnosis indicates are in need of service. Refer to Figure 2 for information relative to parts nomenclature and location.

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