OBA TEMP install

[Rubi04TJ]

Well yesterday i installed my compressor and ran into a few glitches but at least i found a place for it.

These are the bolts holding it in.

My bag of goodies

More goodies.

Goodies hooked up

Goodies Pressurized

Yeah i know.. a propain canister but like I said it is temperary as without the extra space the compressor builds pressure almost instantly to 150lbs at the head. So when you are filling up your tires and you take the filler off of the valve stem the compressor just builds way to much pressure on itself. To minumize this i needed a tank.. this works for now and gives me enough time to check and move around while the compressor is still on.

I do plan on going to a larger 1 or 2 gallon tank and a relief valve to solve this problem totally but like i said this works for now.

150 psi at the head... nice... I have a system the does the same thing... i eliminated the storage tank and air chucj that has a squeeze lever to fill the tire, I tie wrapped it in the open position so air always comes out as long as the compressor is on... I just walk around and fill as needed then shut the system off...

You need a Flow-Thru Chuck or you gonna blow-up that compressor.

or a pressure relief valve like i stated above... :wink:

i went to home depot and bought a hose repair kit.. cut the crappy end off and put the repair kit on, works like a charm.

There's got to be a 12volt pressure swith system available to shut down the compressor. hmmmm....good project for today.

these guys have everything we need.

12 Volt Pressure Switch - 00308
12 Volt Pressure Switch

Pressure switch keeps your air tank at preset level. Available in two ranges, either80-105 psi (great for use with ARB's) 90-125 psi or 110-145 psi.
Made by Texas Instruments. var sc_project=225349; $24.95

sweet!

I think i'm going to basically copy xjmarks setup.

As far as a pressure switch - and voltage type will do- the 'relay' is tripped by pressure - not voltage. I used one off an old compressor.

Can you post a list of part #'s and where you got them for the rest of us?

 

[NomadJeep]

so Frank, how did you do yours, any pics or part lists?

Mine's not permenantly mounted yet. I used an old 3.2 gallon tank and pressure switch off an old air nailer compressor that blew up a long time ago. I just put a male QD on the tank's manifold. On the Pep boys compressor - I cut the black leader hose with the proprietary odd QD fitting. I used a 1/4" hose barb to 1/4" MPT fitting with a standard QD. I wired +/- 12 volt DC leads into the pressure relay(where the 110VAC cord used to go) I wired the +/- leads from the compressor to the pressure relay where the original 110V motor used to hook up. When I arm the pressure switch - the compressor turns on at 80lbs and off at 115lbs. I was able to run an impact wrench intermittently.


Next step is to find somewhere to mount the set-up in the Jeep. No need to mount it permanent until I get an ARB...

I'll try to take some photo's this weekend.

It's on sale again! :dance:
I bought the complete MaxAIR 4.0 On-Board Air compressor system for 399 earlier this year. I figured do it once, do it right. 100% duty cycle. Works awesome. Basically, with the sale you pay for the compressor and tank, and get all of the other components for free. They add up quick.:wink:
Here's what you get with the kit and the part numbers.

Here's how I set mine up for portable use. Eventually, I'll probably mount it solid in the YJ, however for now - it't nice to have it portable to hook up to any 12v source (spare battery, jumper box, ATV, and someone elses vehicle!)

Parts list:
For me - an old 110VAC nailgun compressor with dead pump
MF 1050 pepboys compressor
(3) 1/4" hose barb to 1'4"MPTF and QDs (to cut into the propriatary leader lines that came with the MF 1050

For you:
MF 50 PepBoys compressor (or expensive alternative compressor)
Some sort of air tank (or air tight bumper)
One-Way unloader valve
Pressure relay
Pop-off valve for tank
1/4" hose barb fittings / NPT (AKA -air hose repair kits)
Air-line quick disconnects and fittings for 1/4"NPT. Sections of airline
10 gauge wire and connectors.
Gauge
Air Chuck

Here's some photo's of my setup (sorry for the large pics):

On the last pics of the relay - it's a standard 110V pressure relay. The bottom leads (to the right and lower) go to the 12V source (line voltage). The top set (to the left) go to the compressor motor. Just like a regular home/shop compressor.

SWEET, gotta keep my eyes open for small donor compressor. Hmmm, we have an airtool repair place in town. Maybe check out behind the shop. :twisted:

 

[jon]

these are some neat setups guys, but I do have to say. I like the Sanden in my heap. Especially since I am using factory wiring and the ecm t o run it.

Ecm bumps up the throttle for me when it come on :lol: .

Now just to figure out the crusise control wiring so I can use it as a hand throttle

 

[JeepinMaxx]

Jon - any special modifications needed to the compressor to run air? Did you need an oiling system?

 

[jon]

air filter and inline oiler on the inlet. and seperator on the outlet

 

[JeepinMaxx]

Here's the mounted install - I added a $19 12V fan that stays on to cool the compressor (even while the the compressor is off). Of course the whole thing is temporary until the off season when I get a chance to mount it underhood and hidden.

sorry again fo the large pics...

That's some great work Frank. 8)
It's good to see people with attention to detail when building things.

Over-kill engineered as some people say, but there's nothing wrong with over kill. I like it.

 

[JeepinMaxx]

Unfortunately (to my wife) as an engineer - I over engineer EVERYthing! Sheds with trussed roofs, Decks with I-beams, YJ's with 4.56, etc... :wink:
