I know this ? Was asked

But do I have to have a air tank or can I just run the air straight off ac and cut out the ressure switches an ect and only have the oilers an the on and off switch for the ac clutch? I rarely use air as I usually only 4*4 in snow an have no reason to drop my psi in my tires. So id only use it when the pressure is low which is very rare. Thank you

Sure, you can run straight off the compressor, it will just take longer to air up a tire, and its doubtful that it would run an air tool (if you ever wanted to), with no air reservoir.

When it comes down to it, it's really not that much more expensive to get an air tank. When I did my conversion, I used med-high quality parts for the oiler and air/oil separator (de-oiler); so the added cost of a tank would have been relatively nothing. You can find them on craigslist for cheap. Look for a cheap pancake compressor and just pull the motor/pump off and use the tank.

The only problem with a tank is finding a place to put it. I wanted mine outside of the cabin, so I cheated and made my own. 2 lengths of 3/16" x 4" x 4" tube made approx 3 gallons (IIRC). I put it under the driver seat; it's plenty strong and made a great skid plate. It sits about an inch lower than the frame rail, but well above any stock style skid plate.

The problem is, it's sitting in my garage unused right now. Want it? I'm up in Portland so shipping should be too expensive.

Here's pic of the mounting location... (it's the red thing)

Now that I've takin out all of my ac parts (not the compressor itself, just the hoses, the radiator type piece in front of the radiatot) my jeep makes a whistle sound while running an driving. Does anyone know why its doin that an if its bad and how do I stop it?

Check the idle pulleys. Mine made a whistle sounds and a few starts later, shot bearings across the garage. If the compressor hasn't run in a while, it'll probably be puttin more stress on the pulleys

Could simply be because of altered airflow across the radiator, due to the AC condenser being removed.

Box in your bumpers or use pipe for bumpers for an air tank.

Then came the intake. The Sanden compressors are lubricated by the freon in the A/C system. With no freon you have to have an alternate way of lubricating the conpressor. The most common and efficent method is to use an inline air tool oiler, which is what i did.

I am in the process of converting my Sanden compressor to OBA. I think I have all of the fittings, tubing, oilers, etc set up correctly... I am struggling with which wire on the the compressor to tie into a manual switch and pressure regulator switch. Can anyone provide a picture or written instructions?

EDIT: OK, I figured it out. There are two wire going into the compressor. One that terminates on the outside of the plate that holds the clutch assembly on (this is the ground), and the other wire goes into the clutch (this is the one that provides power to activate the clutch).

What a killer write up. Thanks so much Russo! I'll be doing this once I can start wrenching on the Jeep again. Bookmarked!

I am stoked I have been wanting/reading on how to get OBA for a while. $$$ being the big issue. My jeep doesn't have AC, but it should be easy enough to pick up a compressor and bracket and new belt. Will add a bit to the total price, but well worth it.

How does your 99 not have AC? I thought it was a standard 97 +. I'd love to see a pic of your engine bay.
