So i finally started my a/c to oba swap the other day. My 94 had a different a/c compressor where the ports coming out the back are horizontal of each other instead of vertical and i could not find any addapters that would work with it. so i had to get a compressor from the junkyard. I found one that i pulled out of a 92 cherokee and it was the only one they had with the vertical mounting bolts to match the one i had on my jeep.
For the compressor i used You will need to get some 3/4 to 1/4 pipe reducers so that you can run the propper air fittings. i made everthing to work with 1/4in NPT fittings to keep things simmple. Since the compressor is normally lubricated by the freon you will need to put an in-line oiler on the suction side like i did here. i also ran a hose with a valve cover breather/filter over by the battery to draw in some relitively cool air. i found my in-line oiler at sears and it was about 12 bucks.
For the discharge side of the compressor i used a some of brass fittings and tubes to help disipate the heat as you will eventually melt the air hose if you run it directly from the compressor. I set up a one way check valve that goes into the filter dryer which will catch the oil coming out of the compressor as you dont want the oil in your lines. The filter/dryer was only 11 bucks at lows and i had to get the check valve from OSH like 6 bucks.
Underhood plumbing compleet. you will need about 30ft of air hose, i bought a roll of 50ft as it was only 15 bucks.
I chose to run my air hose under my jeep because it was simple to do and will make any repairs much more easy. i drilled a hole in the grommet thats half hidden behind the taillight and ran a brass elbow through it so i wouldnt be pinching the hose and it looks neater.
I know my tank is small but it works for now. the hose goes into a T fitting where i have the safety pressure switch on as well(its hidding behind the pressure regulator) and the pressure regulator is only there teporarally as it will be run off a nother T fitting. i wil be getting an electric pressure switch to turn the compressor on and off when the pressure gets to a certain point in a couple of days and that will sit above the pressure valve on the end of that T fitting. i will post up a closer picture of that once i get it all finnished.
i was able to test run it and so far it only takes 15 seconds to fill up my 1.5 gallon tank to 150 psi at an idle. will do a more extensive run when i get the pressure switch installed.:cheers:
