Anyone have tips on how to do this. I had an article fot the jeep A/C but lost it. I got my truck last week and will start working on it now. The axle's are open on both ends so I'm going to convert this and do all other smaller mods first while I have a chance.
 
some compressors are lubed by the freon instead of an oil bath like the York. Make sure yours isn't like that (some older Jeeps are like this), if it is, you'll have to put oil in the intake every so often to keep it from locking up. About a tea spoon full maybe every 2 months or so, just depends on how much you use it. Make sure you have an air filter in the system somewhere or you'll have oil coming out every time you use the air.

Jut put a filter on the intake and run the output to a tank. Of course you'll have to install a solenoid to stop the compressor at certain PSI and such. I had mine on a toggle switch in the cab so I can turn it on and off when I wanted so it isn't running all of the time.

You don't need a tank unless you want to run air tools or similar. Tires, toys, balls, air mattress, blow up dolls, etc will air up fine without a tank.

Where did you find that article about the air compresser/AC for the jeep even better if for the cherokee, ive found a few but none are very clear or easy to follow, sorry to kinda jump in but it relates to your post.

I can't remember I'll look and see if it's at my house. I think it was on this site a long time ago. I think it's still at my house though. If I find it I'll scan it and emial it to you.
 
I found an article. Go to google and type in jeep on board air. You will have more than enough information and diagrams. Jon's On-Board Air page has alot of info into converting these. I thought there was more into it than that. You probably have a good setup already because what I've read chry/dodge had the strongest comps. Long as they carried into jeep -- which makes since. I'm going to check and make sure my air comp is a york and start the convo.

Thanks All
 
My XJ has a Sanden compressor that requires lubrication. I simply used an oiler on the intake and a colesking filter on the output. No tank in my set up. I have about $100 in parts I got from tractor Supply and Northern Tool. If you have the old style freon in your AC system make sure you get it evacuated and recovered properly.

The orange thing in the pic is the filter, the blue thing the manifold, then a pressure guage and behind that the pressure switch. Be sure to get a pressure relief switch.

Here's the intake, got a rice boy breather/filter and then the lubricator. Worked well for over a year.

At 1100RPM I can fill my swamper up in less than 1.5 minutes.

The Toyota AC unit is lubed by the freon. It puts out good pressure, but usually the longivetly can be a problem. I have scene where people run a automatic drip unit that can help the AC compressor last a good bit longer though.
