I know you(or someone) had at one time figured out something about using a suspension system air compressor from an older Caddie(or something) to use as an air supply for air lockers. Do you still have this info somewhere?? Did these compressor units come with a small tank/reservoir, or did you have to add a tank to make it complete??

Thanks!!

This is the quick-n-dirty instruction sheet. Now that this is done, I can do the writup on it.

Parts List:
* Two 1/8" NPT T-adaptors
*Two 1/8" pipe nipples (one 1" one, and one short one)
* One 105psi pressure switch
* One Caddilac air compressor
* One female quick-disconnect (with female 1/4" NPT input)
* One 1/4" (male) to 1/8" (female) NPT adaptor
* One ARB solonoid
* One 1/8" instant pipe fitting

First of all, you need to realize just what you are replacing. The ARB compressor has three 1/8" BST female fittings on it. Thankfully for us, we can use 1/8" NPT fittings as a replacment.

The three fittings are for the two lockers and the pressure switch. One of them can also be used for airing up tires, by using the ARB tire fill kit.

(Quick hint: use teflon tape (2 layers) on each male NPT before screwing it into the associated female fitting)

So, we need 3 outputs, and one input (for the compressor). In the Lowes/Home Depot based garage, I did this with two 1/8" NPT T-adaptors. These each have three 1/8" female fittings. One fitting on each T-adaptor goes to the other T-adaptor.

So now we have our "manifold." We are going to connect the compressor input, locker output, pressure switch, and female disconnect to this manifold. I suggest connecting the compressor input to one "end" of the manifold. Then the quick-disconnect, then the ARB solonoid, then the pressure switch at the other end of the manifold.

Note: DO NOT TIGHTEN THE ARB SOLONOID TO THE MANIFOLD BY TURNING ON THE BLACK PART OF IT - USE A WRENCH ON THE ALUMINUM HOUSING

The only other useful information that I have for you is on the parts sources:
Pressure Switch: 12V pressure switch from http://www.4x4connection.com - pick the 105psi one, which is currently at: http://store.yahoo.com/cruiserconnectio ... esswi.html
ARB Switch: Part number LOAR180209 from http://www.4x4connection.com
ARB Switch cover: Part number LOAR180212 from http://www.4x4connection.com
1/8" Instant pipe fitting: Part number 51495K181 from http://www.mcmaster.com

Just an FYI......

Found the pressure switches here for a lot less $$$ http://shop.sportruck.com/airlift/fitti ... 20Switches
They emailed me and told me shpiing was only a couple of dollars so the total from them is about $20 vs. $33-$35 from most other places I found.

Too bad I'd already ordered one for $25 plus $8 shipping when I found the place above. :( :x

If a person were smart, they'd also get a couple of the ""Unions" to carry with them in case they break a hose and need to splice it back together. The place above has them for $2.50 each. I think ARB sells a kit but it's pretty damn expensive IIRC. Not sure these .25" unions would work with the 5mm hose though. Probably not. :cry:
