AC pump conversion to air pump

[Tucsontoy]

Has anyone converted an A/C compressor to a typical air supply compressor using the current style unit found on the new Duramax. I am building a buggy that will not use the AC so rather than try to switch to the older York models I am planning to use the stock compressor to fill a small air receiver for tires or tools. It looks like adding some kind of oil injector into the fresh air should work....
Any ideas?

I know you said you didn't want to convert a york but there is a company that sells a kit that is about a 30 min bolt on that goes where the second alternator bracket is. No converting necessary. It flows enough to run a good 1/2in impact steady for quite a while.
I had trouble with my oil injecting setup on the older ones, but I don't see why you couldn't get it to work. How long are you planning to run it at a time, just long enough to fill a tank or setting it up on a pressure switch?

All these OBA kits bolt up to where a dual CP3 would huh?

All that I've seen for a Dmax do. We run a auto leveling airbag set up on a few duramaxes around here and have a lot of trouble with elec not holding up. We mounted a 5 gal tank and two elec compressers behind the bumper to keep the 2cp3's. They both had a 100% DC on them and they still wont last more than 3 months at a time, so we checked around and found this company that made the York kits for the LB7 and LLY, gave them the mesurements for an LBZ and they made the setup for it.

Space?

I am already running dual alternators with due to all of the extra stuff on my buggy. Space is the problem with the big York units that I have seen. Can York convert a standard AC pump? The dual alternator setup limits the belts available to just one which creats a problem changing the A/c position and pulley diameter.
Thanks for the input...

My likes have always been Viair, from bagged trucks air supply to guys pullin their toy haulers. A good 450C or 550C that has a great duty cycle and throws good CFM plumbed to an 8 gallon tank mounting with brackets where the spare goes is what my plan was on my 05... not sure if I want the weight on my 08.

An ac compressor would fry due to the lack of oil keeping it lubed.

fried compressor..

I agree that without an oil injection it will not last long. Rather that re-invent the wheel, I am hoping someone has or knows of an injection system before I start designing one at the expense of a couple of compressors before I get it right.

mobile air compressor question

I all else fails and the GM Ac unit does not work out I may take a serious look at the new Warn VTC V-twin portable unit. I saw one at the SEMA Show last fall. It is 8 cfm @ 90 psi. But, that is a last resort. Without the AC unit in place I end up with belt issues running dual alternators.

The way an ac comp works is freon and oil come in the suction line and also comes out the discharge line. So you would need an oil sperator on the discharge line that would feed it back to the comp on the suction line.

I used an air tool oiler for a while and that's why mine fried. I forgot to keep it filled up. They will last forever if you keep them oiled, just don't forget to drain the tank every couple of times you use it to keep as much oil out as possible. York doesn't convert GM compressors over they use factory ac units off of Volvo's(made by york) because they have an oil res in the comp and need no lube from the freon.

oil options

I have heard of a tool oiler on the inlet then a filter/seperator on the discharge. The seperator was piped to refill the intake oiler. I was hoping sombody here had done the same thing..... or know someone who has....

I didn't put that much thought into it when I did it. If I had put a separator on it I'm sure it would have lasted a long time. I have seen them last for years on trucks when the people kept them oiled. The kit's are just nice because they have a pressure switch with them and all the lines and stuff. But I have to have my dual fuelers so I'm stuck with electric for now.
