filling tires with A/C compressor?

[FinnDRZ]

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...

In that case I would build it inside and inatall it later. It's 07:15 here and already 60f.

 

[JEBSR]

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.)

 

[FinnDRZ]

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..

Sounds like it's time for some snow wheelin then!!!

No
Left rear tire flat.... and the compressor isn't done yet, as you know

I'll take few beers, and go to sauna.

Ha, you crazy Finns.
