Default DIY on-board air

was browsing thru ebay and something in particular caught my attention. a guy is selling an OE a/c compressor that leaks slightly... but he said it would be perfect for making your own on-board air system. thinking about it initially, it seems real feasable.

anyone familiar with doing this? what kind of pressure would an a/c compressor make? also making me wonder would the clutch work like it's supposed to at the correct pressure?

i'm planning on installing train horns in the spring, and it would be killer to drive outta the dunes, right past the air-up line.

OBA has been discussed on here before.

Also there are many member/shops that carry ultimate air parts http://www.ultimate-air.com/dealers.htm

Depending on the compressor it may not be a good candidate. Some will not last long because the freon held the lubricant. If you put an oiler on the intake it helps, but they still do not last as a York compressor. A York is another type of A/C compressor that has a oil reservoir in it.

search around for York OBA and you will get a lot of info

yes, i actually have done a bit of digging thru old posts, and see the York (or "yoke" lol) mentioned often. i just happened to see the OE compressor on fleabay mentioned being used for air and really never put two and two together before i read that.

so riddle me this; realistically, how effective are the 12v pumps (100% duty cycle), when used with a 2-5 gal tank? again, i've seen mention of it, but noone has really said if it works well or takes half an hour to air up.

I currently have a York setup w/ a 2.5 gallon tank. Last summer I was with a group and one guy had a setup similar to what you are questioning. It worked fine I thought when we need it, but he openly stated more than once during a tire repair that he would never do it again (he had a York on his YJ prior to buying a TJ).

I think his biggest issue was CFM and ability to recover. And secondly it was a space issue. Jeeps are small and when you put a system like his in the rear is takes up too much space. A York under hood coupled with a 2.5g tank mounted under the drivers seat area saves takes up no space in the tub.

FWIW

i built my own OBA using a GM radial style compressor...pumps out continous 125 PSI, not sure how much CFM but it runs an air gun no problem and build pressure quickly...i aired up a 33" tire from 10 PSI in about 2 minutes.

I have my OE sanden compressor converter for OBA use. Works great. No tank will air up a 31 inch tire in about a minute to decent pressure.

I have seated beads with it, and used it to fill up TONS of inflatable toys and mattresses. Works very well.

will be adding a tank to make it not have to run continuously and further speed up fills. Also would be nice to have an idle bump as it pumps faster w/ RPM. I will probabley rig something up to work.

I have a inline filter and luber on mine but they were cheap HF units and i dont think they do anything so I just spray some oil in there every couple of uses.
