This is an interresting project that can really make a difference in your 4x4'ing adventures. Basically you're setting up an Air compressor in your vehicle. I started by collecting the components. You need a A/C Compressor, the brackets for your engine, Hoses, a pressure switch, a Tank, and fittings.

My Jeep is a YJ, with the AMC 258 engine. It did not come with AC, since most jeeps are soft tops. I'd read that a lot of the early AMC's the Cherokee, the Eagle and even the Grimlin all had 258's and AC. So off to the junk yards, I found a dead AMC Eagle that had the brackets to mount a A/C compressor. I also found that the same brackets will fit some 4.0L engines. I had to shave a little off the bottom of one bracket so it would fit my engine better, so don't be afraid to modify anything. Be aware when looking at brackets that there are a few different types for different belt configurations (serpintine / V-belt).

I got the Compressor mount plate, the Belt tensioner and the Alternator mounting bracket, along with all the bolts and nuts I took off to get the brackets. These are important since you don't know what you might need later. Best to err on the side of caution.

Next I needed a compressor. The Best ones I've heard about people using are the York Compressors. and in those there are about 5 different kinds that could work. I think mine is a 12R, meaning it's got a 12" stroke for a LOT of air, thus needing a smaller tank. A lot of the other compressors require an Inline Oiler, which can be a pain, where, the York, does not. Though you still need to have a filter to catch output oil to keep it out of your tank and lines.

Next I needed a Pressure switch to turn the compressor off when the tank is filled. This was easilly obtained from Grangers, Part No. ##### (I'll get this later or you can Email me) This is wired inline with a fuse and a toggle switch mounted in the Cab to turn the OBA system on and off. Wire this into your KEY ON power (Usually Yellow Wired), not constant power (Usually red wired). This Pressure Switch engages and disengages the clutch on the compressor When the PSI reach a certain level.

The Tank, Well I settled on a 2.5Gal Tank, it's plenty to inflate one tire without the pump, and will be enough to run my ARBs. I could have used a smaller one, but mines a pretty good size, though I haven't found a really good mounting location yet. so for now it sits in the back behind the rear seat. Some people use thier custom bumper or even part of their roll cage as a tank, but I don't know how much volume they really get.

I'll add more to this Later when I get more pictures, but you can write me with any questions. Projectjeep@projectjeep.com .
