OnBoard Air Setup for CJ5 - Automotive

PPSIncGa · 02-19-2011, 05:35 PM

What size reserve tank is needed for my onboard air setup to be able to run an air tool to change my wheels? I would like to be able to do it anywhere and just keep an impact wrench in a toolbox. Thanks for any help.

I read that 90 psi is needed, so is it best to have it coming from a seperate compressor independent of the engine or one powered by the engine?
Thanks

If your just looking to change tires, I would probably just look for a cordless electric impact gun. it would save a lot of room in a Jeep.

It all depends on the size of the compressor, how much air the tool uses, and how long you want to run the tool. I use an ac compressor in my Jeep with a 3 gallon tank and have no issues with running low on air.

One of the favorites for on board air (OBA) is the York a/c compressor. It's a 2 cyl model with it's own oil sump, which is why its so popular. Should be relatively easy to find as well as it was used for several years on different vehicles.

Some good info here...

depends on tire size i guess.... i wouldn't go any higher than like 3 gal... space is at a premium in those... u never have enough room

i would go with the cordless impact, however, it would probably be dead when i went to use it... lol

It takes a heck of a lot of air to run a impact wrench. There is noway a 3 gallon tank is going to do anything for you.
