HR-6 Component View:

The Harrison HR-6 compressor is a fixed displacement axial piston pump, with three double-ended pistons actuated by an axial (swash) plate shaft assembly. The main parts are the front and rear cylinder the each and axial swash plate, piston group, and valve mechanisms. The cylinders and heads provide an integral external shell.

The piston group of the compressor is not serviceable. If Piston, bearing, ball shoe, shaft and axial plate, or cylinder repair is needed, replace the internal cylinder assembly. All clutch parts, valve mechanisms, and head assemblies are serviceable, plus seals and gaskets.

Refrigerant oil, dispersed in the refrigerant vapor, lubricates the system.

The front head is shown with three integral mounting flange ears. These ears have 19 mm flats cast to provide for a wrench to be used as a prying means when tensioning the compressor drive belt.

There are two clutch driver designs for the HR-6 compressor: The clutch driver without a torque cushion and the clutch driver having a thin torque cushion.

Note: When servicing clutch drivers with a torque cushion, the clutch hub holding tool J 25030 is used in place of J 33027.

Keep dirt or foreign material from getting on or into the compressor parts and system Keep the work area and tools clean.

Keep the parts clean at all times. Clean assembled parts with Trichloroethane, naphtha, Stoddard solvent, kerosene or equivalent solvent and dry with dry air. Use only lint free cloths to wipe parts.

Drain and measure the refrigerant oil. Add new 525 viscosity refrigerant oil to the compressor.
