Daoes anybody have an under the hood air compressor installed on their first gen?

I have a very small compressor installed next to a one-gallon air tank -- this powers the air horns (all installed by the previous owner). The whole shebang sits atop the driver's side front wheelwell.

A/C compressors

Since the subject came up, I also have a question.



My brother converted the A/C compressor on his '90 Cherokee to an air compressor. Puts our plenty of air and is switched at about 115 psi. It gets used constantly for airing tires up (after off roading), air tools, etc.



I would love to do this on my truck but don't know if it is safe with our air compressors (ie lubrication issues). Does anyone know if this is a doable modification?



Thanks,



Isaac

Ok. . Here we go.





This I know because I've done it with great success. A reciprocating pistion A/C compressor will work as an air compressor these are the fairly large compressors used on some older cars York and other manufactures made them. All you have to do is to make sure the every oil change you check the oil in the case and maintain the level because they will push some oil into the air system.



What I need to know is if you can take a A/C compressor that came on our pickups and make an air compressor? It's a rotary a Sanden I think but I don't have a clue if they can be used for that.

If you really want some air, you can mount an air compressor on your accessory drive like the big rigs, but then all that weight is hanging off the gear housing. It is easy to find yard jockeys and transit buses with "B's" and air compressors,

On board air has a little oiler set up so that the Sandan compressors can be used. It allows a small spray in the intake to lube the compressor.

When you use install the Cummins air compressor driven off of the accesory drive you have to modify the Power steering and vacuum pump. Also the motor mount can cause some problems too.

Do you know about how much air a Sanden would put out? Does on board air have a web site???

Looks like a Sanden can be used with a little lubrication. I haven't found any hard information on cfm etc, but this is now on my list of summer projects.



The air conditioner wasn't doing me alot of good in this state anyways.

I found this air compressor under the hood of a Dodge WC-54 that I just picked up. The truck was converted to air over hydraulic brakes air some point and this is the power source. This unit will be installed on my 1959 W300M. I really like the compressor and wonder how available they are.

I have an on-board air setup on my Jeep. I used the standard A/C compressor that was on the engine I swapped in. It's a Harrison, I believe. The engine is a Chevy 350 TBI. For the lubrication issue, I have mounted a capped tee in the compressor's suction line. Every time or every other time I use the compressor, I pour a little oil into the tee to lube the compressor. Every year or so, I have to dump some oil out of my air tank, but the compressor is happy so far. I should probably buy the lubricator from onboardair.com. York could be a better way to go if you're swapping something in, but this one was on the engine already, so that's what I used. Works great, and pumps my tank up to pressure quickly. Plenty of pressure and volume to re-seat a 38" tire on the wheel.



Besides, who needs A/C on an open Jeep?

 

[dwalker151]

I am thinking about using the one that came on my first gen but I've heard that the rotary compressors don't put out enough air to make the trouble worthwhile. Was the one on your jeep a rotary or an reciprocating?



I'm just not sure if a fat man can part with air condtioning during harvest!!

I'd have to guess mine is rotary. Maybe someone can help out here. It doesn't look like a York at all, which I believe is reciprocating. As far as air output, it does quite well for me. It'll fill large tires quickly, run air tools, etc. I've only needed to use it at idle, even when re-seating a 38" tire that came off the bead. I have a small tank to add volume to the system. Here's a pic, maybe someone can tell more about the compressor. It's the thing with the two aluminum lines coming out the back.



As far as doing without A/C in your truck, I wouldn't give up A/C for air in my truck.
