on board air compressor
I have heard that you can make a onboard air compressor by useing the air conditioning compressor on your truck. I have a 1977 F-150 that has a air conditiong compressor on it.
Anyone know how to go about doing this?

It doesn't get any better than that. Have one on the Jeep with more hours on it than the 60 gallon shop compressor.

The links for that compressor's data are not good. How much does one of those run?
Looks $$$

Sorry for the big picture...I've got one installed on my 97 Ranger (2.3)
http://img6.photobucket.com/albums/v...n/Im001169.jpg
Fill times for 5 gallon tank
At idle, approx 700-900 RPM
0-120 psi - 1 minute flat
0-150 psi - 1 minute, 20 seconds
I used a Sanden 507 from an '87 Jeep Cherokee 4.0l

Watch for cracks in those copper fittings. Copper does not take vibration well.
I changed the picture to a link ( removed the {img} tags) so that people would not have to scroll the forum view.
Let us know how that compressor lasts. I have heard they wear out quickly when used as an air compressor. What do they use for lubricant?

I plan on using it for supplying my (distant) future air suspension setup...so it won't see much use. I plan on using plain ol' used motor oil to lubricate it, mainly because it'll discharge some as it pumps. I think they're designed to use some kinda special oil (can be found at sanden.com) but I figure as long as the level is up where it should be I'll be ok. It won't run nearly as often as it did in it's original application so I'm not too worried. Time will tell though!

I had planned on mounting the check valve near the tank, but that will have to wait until my new gas tank in installed.
Don't have a head pressure release...this is to ensure the compressor doesn't pump up past a certain pressure right? I'll be running a 145on-175off pressure switch. I plan on wiring it up through a relay, and also a switch. I'll mount a guage in my dash, with an LED right beside so I can tell at a glance what my tank pressure is, and if the compressor is pumping. The switch will be a master switch so that nothing works unless it's on.
Any other suggestions?
(Thanks for your input thusfar, I'll try to find some steel fittings.)

The head pressure release is to release the pressure on the compressor so that every time it starts it is not pumping against pressure. You normally hear a "PSST" when your air compressor motor stops. That is the pressure release operating. This is usually used on electric motors tho, maybe some small gas powered rigs too. I just wondered whether you were using one. With the HP you have in your truck you don't need one.
A check valve at the tank is probably a good idea.
There are mentions here re automatic tank drains that you can buy. A search on "compressed air" will probably find them.
