AC compressor conversion

I want to make it an air compressor. It sounds fairly simple.

The two biggest problems I see are the air inlet/outlet and oiling the compressor. The fittings on a '96 4.3 compressor are funny, so I'm going to have to cut the hoses and put barb fittings in them. No big deal. Oiling it seems fairly simple. I can get an air tool oiler and put that on the inlet. Then, on the outlet, I will have to put an oil/water separator to keep the oil out of my air line

Any thoughts? Has anyone done it? Any other tips or advice?

Re: AC compressor conversion

The stock ac unit will not work as an air compressor. a sanden 709 fits in the stock location with an adapter plate of some sort.

I agree. Altho it has been done, it's not worth the hassle. Your AC Comp uses a "Wobble Plate" design. Which is NOT efficient in air. Go with the Sanden if you want a fairly basic swap.

Re: AC compressor conversion

thanks for the heads up then. if I'm going to be buying something, I'll just go with a Viair 380c or larger and put a 2nd AD244 alternator in the AC location.
