    My A/C is not working, and I'd like to remove it, and use the A/C compressor for filling tires, and maybe use some air tools. Has anyone tried to use the original Harrison compressor for those purposes?
    I know there are better compressors, but I'd like to use that Harrison, because it is already there...

    I think there are a few members who have done this but you need to keep the compressor oil as it would've originally got it's lubrication from the a/c gas. I've heard that they don't last too long. I was going to go that route untill I read up on it. I know have a Kilby OBA set up and it's great.

    I used to work at a salvage yard when I was a kid and my boss made a system like that. Took an early 80's k20 and put a 60 gallon tank in the bed. He used the original compressor and just cut the low pressure line at the compressor and put an air filter over the line. I think it was an atv or motorcycle crankcase filter or something. He just tightened it up with a clamp where we could slide it off and put air tool oil in it. You have to be sure you have a really good oil trap and water filter though. Otherwise you will fill your tires with oil.

    Squirt oil into it when you use it and get a good oil trap.

    I have a friend that was working on routing the oil back out of the trap into the compressor, but he never finished. It would be a good way to set that up though.

    I have several friends who are using an A/C compressor without a seperate oiling system for this purpose. The one guy just has a "T" in the inlet hose that has a screwoff lid..........just unscrew it, put a few drops of oil in it, and reinstall the lid.

    Thanks :)
    How much oil is needed to properly lubricate the compressor?
    about 2-3 drops / minute? or something like that? (don't say: "try and find out")

    Should it be something like this: Inlet air filter - oiler - compressor - oil and water separator - non-return valve - air tank with pressure switch.

    I'd do as you say but ... non-return valve - air block with gauge,pressure switch, safety blow off valve and take offs for air lines and then the tank.
    Run it all in 10mm nylon and use the neat T pieces to take off for coupling points.

    OK, I have plenty of time for thinking, before I begin to work on it. Temperature today is -10c (14F), and I dont have a warm carage...

    Yea I don't think I could get motivated to work in temps like that. I was just complaining about it being in the 50's here (10:23 P.M.)

    Of course, my Blazer doesn't fit in to my small cold carage, and here is about 10-15 cm (4-6 inch) snow. So I'll wait for the next summer...

    So you guys keep on laughing.. :)
