Delphi Harrison V5 A/C Compressor - Full Teardown and Reseal

In this rather lengthy video, I teardown a Delphi Harrison V5 air conditioning compressor. This compressor was used for many years across the General Motors car makes. In my other videos, people have asked me the details about the parts cleaning and other things that I often skip over. This video is long because I have included the parts cleaning and other details that I normally skip over.

It is a 5-cylinder, axial-piston variable displacement refrigerant gas compressor. The compensating valve changes pumping volume to maintain approx. 25 to 30 PSI of pressure on the low-pressure side of the A/C system.

These compressors are very durable because they contain their own lubrication oil reservoir. They will tolerate low refrigerant (Freon) charge better than other designs.

These compressors were used from the mid-80's through the 2000's. The early ones nearly all leak by now, due to seal and o-ring deterioration.

The process is straightforward to teardown, refurbish, and re-assemble the compressor. This process involves the following main tasks:

External parts removal.
Sealing of openings.
External cleaning.
Disassembly.
Inspection of parts.
Polishing of seal surfaces.
Prelubrication of working parts.
Re-assembly with new O-rings.
Install shaft seal.
Install new pulley bearing.
Install external parts.
Set clutch air-gap.
Vacuum check.

ADDITIONAL INFO (21 March 2016): Please see the following link for complete seal kits, which have the compensating control valve O-rings in them. My kits were older; whereas the newer ones are available complete. Search the store for V5 seal kits and you will find the complete version.
