A/C compressor on-board air

[feellnfroggy]

Has anyone read or completed the a/c compressor on board air mod posted in the tech section? I read through it and it looks simple and affordable enough, but it was very detailed and I dont know much about air compressors, can anyone shed more light on the mod or post a more detailed writeup? Or anyone in my area interested in getting together and doing this to one of our trucks?(or all of them)

I glanced over it some months ago. It didn't look too complicated, I think it was more parts intensive than anything.

Think of an air compressor like a little 1 cylinder 2 stroker.Piston goes down, pulls air in to a cylinder, piston goes up, pushes it into a tank of some sort where the addition of more air creates pressure as more air is forced into that same volume of space. Only difference is that its driven by an electric motor or a belt instead of its own momentum and expanding gases.

have you looked at my build thread? I have the OBA

i know i have siad this atleast once on here but you CANT use an a/c compressor as a air compressor they rely on the freon as lube and once you take that out of the system it will burn and lock up and you will snap your belt off. you can use a YORK air compressor and they are belt driven and they will produce the same if not a bit more air than your a/c compressor will ever be able to do. i can get you write ups on how to install one. i had one on my toyota and it was amazing i used it to air up my tires after a day of muddin or some mild trail ridding. i had it fill up an old scba that i got from our vol. fire dept. it help about 45 mins of air so thats about 150 or so psi it was about a 3 gallon tank. here is a pic of my york air compressor before i installed it in my yota. you can see the breather on one side and the output on the other side. they have their own oil resever so no tapping into your trucks oil system

I suppose I should have read this ten years ago when I converted my a/c compressor to oba, strange that mine is still working flawlessly.

i was going to say the exact same thing lol. I guess i should go tell both of my OBA setups that they need to break down already!

 

[bigcountry]

ok then how did u convert it to oba then?

what do you mean? are you asking how I'm using a sanson a/c compressor?

heres the link to how i installed my york http://www.yotatech.com/f116/oba-my-95-4r-lots-pics-155109/

yea cause every person i talked to before i put my york oba on told me that a a/c comp wouldnt work cause it would burn up without the freon in the system not sayin yall r wrong or tryin to be a smart arse just merly tryin to figure out how all the mechanics i talked to told me that freon was the lube in the a/c compressors and taking it out would cause it to burn and lock up

 

[NMB2]

you just keep a can of WD40 or air tool oil. Just oil it up alittle before each use.

 

[bigcountry]

wait so you have to oil the compressor up before you use it? hmmmm id prolly forget to do that hahahaha id more than likely be in such a hurry and just fire it up and go. thats why i like york its already got an oil reserve in it so i would burn it up

 

[NMB2]

the york is nicer but harder to find. and i dont oil it each time before i use it admitedly, but is recommended.

The REFRIGERANT (Freon is a brand name for R-12, which is no longer produced, by Federal law all new cars after 1994 were produced with R-134a and all previous cars were to be retrofitted for R-134a) is not actually the compressor lube. It contains PAG oil which is used to lube the system and keep the o-rings from going brittle and breaking.

The compressor will run itself dry and lock up eventually if you don't oil it with something, but it would take hours of dry operation before the oil was forced out and lockup occurred. It will work, you just have to treat it like any other air tool and oil it before you use it.
