'89 R3500 Crew Cab 2wd to 4wd conversion & beyond

Started out with 2wd TBI350 with SM465 to current 4wd with 454, 700r4, NP241
Got an exciting package from ORD today....

See Scott we posted instead of lurking.

Nice air locker!
 
Thanks you all! I'm excited to get this in the truck. It's for the Dana 60.
 
Now that we're doing more of the easier, scenic trails it'll be nice not to always have the front locked up.
 
Mounted a 5 gallon aluminum air tank.

The ARB compressor runs between 130-150psi. I'm going to add a regulator to the line with the air coupler and set it at about 90psi for tools and airing up tires. My thinking is that since the compressor's duty cycle is 130-150psi, running stuff at 90psi will help the compressor to keep up easier. Plus the air impact I have is rated for 90psi anyway.

I'm also going to add an air pressure gauge to the rear most port of the tank so I can read it standing at the back of the truck. I'm also going to run an air line from the tank to the ARB solenoid.
 
I have much the same idea for this as you, post up lots of pics!
 
Will do. It's surprising how long it takes to charge a 5 gallon tank to 150psi.
 
Yeah i was thinking that using the house compressor to pre-charge it would be good, then just use the lil pump to maintain. In Moab or such, just recharge it at the gas station if you do tires with it.

Havent thought it all the way through yet :thinking:
 
What compressor are you getting?

I went for the biggest ARB because I want to run air tools, air horns, and air bags.
 
Mounted my regulator. It's a small IR unit I got for $25 on Amazon:

Had to mount it upside down so the IN and OUT ports were on the correct sides.

I'm a little concerned about the regulator kinda sticking out there, it might get hit when we're loading stuff. I was looking at adding a 90° elbow instead of the 45° but all the elbows I've found seem to have restricted flow and I want to keep that open for the air tools. Plus I'm afraid it would jam me up to tight to my cover over the compressor and I wouldn't have room to connect the hose.

You can also see I added a pressure gauge at the back of the tank. The annoying this is by the time I got it tight enough not to leak it's barely readable. However I can see it standing at the back of the truck so it still gives me some benefit.
 
Hmm. I get the feeling you will come up with better solutions for the gauge and reg. They would be fine forever as is, but you (like me) don't seem very good at forgetting about something that bugs you.
 
Honestly I don't think a 90 will kill your volume through the line that much usually the fitting on the air tool necks down to really small anyways. And for the gauge you could get the plastic airline they use on semis and run it from the tank to the back of the bed and have a gauge in a little panel under the bed rail and you could also put a T fitting too for your air tools there so you don't have to climb over the bedrail to use them.
 
If you are going to remote mount the gauge, move that all the way to the dash board. Just like a Peterbuilt, yeehaw!
 
I realize I forgot to post some info before. The gauge at the back of the tank wasn't in my initial plan. I was using these aluminum plugs for the unused ports:

They leaked and I couldn't get them to seal. So I went to get regular brass fittings and saw the gauge and I figured why put that in. So it wasn't as thought out as I would have normally done.

I actually have a Viair remote I was thinking about putting on the dash.

I was just talking about this with a coworker. I find it interesting the impact calls for minimum hose size of 3/8" and yet uses 1/4" fittings.
