Most A/C compressors lubricate themselves with the freon that flows through the A/C system. In order to use these compressors for pumping air, you need to have an external oiler feeding air into the intake hose and a filter to…

The actual list of supplies required will vary from one rig to another, but this is what I used and what it cost me. Much of the stuff came from the Surplus Center, a national mail-order place specializing in hydraulics,…

I chose to mount the hose connectors and stuff on the inside of my front right wheel well near the factory jack. That location provides easy access and also keeps everything above the water line should I decide to ford…

All A/C compressors need to be lubricated in some way, whether they’re pumping freon or air. Most compressors are lubricated by the liquid freon that they pump. The York, on the other hand, has a separate oil reservoir that it…

The York compressor can be mounted vertically or horizontally to either side. However, if mounted horizontally, the manufacturer recommends that the suction port be on top. This is most likely due to the internal oiling system locating an oil return…

York compressors are easy to find because they were so common on older vehicles. From the mid-1970’s to the mid-1980’s, they were used on Ford, AMC (including Jeep), International Harvester, Oldsmobile, Volvo, and Porsche vehicles. I know Jeep used them…

You really should have a tank for any good onboard air setup. This ensures that you still have air if your engine dies, and it lets you run things like air tools that suck more volume than your compressor can…

This is a collection of useful comments that people on the various Jeep newsgroups and mailing lists have made about converting York (or similar) air conditioning compressors for use as on-board air compressors. From: Fieldsj@uwwvax.uww.edu (Jerry Fields) Date: 19 Dec…
