GENERAL DESC RIPTIO N
The HR6-HE Automotive Conditioning Compressor ;
and Clutch Assembly is a lightweight; six cylinder axial design
consisting of three double ended pistons and weighs 5.8 kg
(12.7 lbs.)
,

Although the HR6-HE compressor is the same Tor all
vehicle applications, there are. differences in installations,
mounting brackets, pulleys, torque cushions'and. switches;
none of which will affect the following overhaul procedures. .
, There are two clutch-driver designs for the HR6-HE
compressor. The clutch driver, without.a torque cushion and the
clutch driver having a thin torque cushion (Fig. !). V V

Service.compressors are supplied with either the control
switches assembled in,the rear head or a; plug may be found
where a control switch is required. If the service, compressor
.requires control switches, the plug may be removed from the
appropriate rear head switch cavity of the replaced compressor
and assembled as prescribed in this manual.
When servicing the compressor, keep dirt or foreign
material from getting on or into the compressor parts and
system. Clean tools and a clean work area are important for
proper service.The compressor connections and the outside of
the compressor should be cleaned before any “oh vehicle”
repairs, or before removal of the compressor. Jhe.'parts, must be
kept clean at all times and ctny.pafts to be reassembled should
be cleaned with trichlorOethane, naphtha,; Stoddard solvent,
kerosene or equivalent and dried with dry air. When necessary
to use a cloth on any part, it should be of a non-lint producing
type, ' '

The operations described below are based on bench
overhaul with the compressor removed from the vehicle,
except as noted. They have been prepared in order of
.accessibility of the . components. When a Compressor is
removed from the vehicle for servicing, the amount pf oil
remaining iri the compressor should be. drained, measured
