On Board Air
« on: March 07, 2017, 09:37:52 AM »
This isnt going to be a DIY


One of my least favorite parts of offroading is airing back up. IT SUX

There are 2 typical routes of airing up,
co2 - you blow your wad on a tank, regulator, hose, etc. Carry around the potential bomb in the back of your jeep, freeze your booger pickers while the air chuck turns to ice... Good Times

Pep boys compressor- you get a little cheesy compressor designed to fill up Kia Rio tires, wait around while it fills 4 37'' tires, and then have the head of the compressor brand you when packing it all up to go home....

Well after a year of sitting on the healing shelf, I have a better way ! About a year ago I received from Henry, A york 210 compressor. For anyone who dosn't know the intended use of the compressor is to pump Freon. What makes this pump different from a normal A/C compressor, is the york has a dedicated oil sump; what for keeping your jibbly bits lubricated.



The compressor at 2000 rpm will deliver 170 psi @ 7CFM

The first step of the process was to track down a different front pulley configuration. The original compressor used a V belt setup, the jeep obviously runs a serpentine belt.  after some google searching, A freightliner part number turned out being the solution.

Ill post pictures of the bracket when it gets removed for paint. Alot of people online need to run a custom belt when running a York. Keeping with the " readily available parts" theme, I was able to retain the stock jeep serpentine belt used for jeeps with A/C ( Took 12 hours of planning and fabrication)      WINNN!!!!

The next step is how to distribute the air. The setup on my jeep will not have a tank, My thought was to build a very fancy air distribution block.

Block fittings
-pressure in
-1/8 pressure switch
-pressure relif
-gauge
-quick connect

There will be a main power switch in the cab, When on it will "Arm" the relay. When an appliance is plugged into the air manifold, there will be a pressure drop which will cycle on the fan clutch. The compressor clutch will stay on, until the pressure switch sees 110 psi.

Time for the block. One thing you will notice with any onboard air setup, there are wires and hoses everywhere. By making everything mount in one spot my goal is to eliminate that. after some careful planning it was time to start making chips..

The air block will mount on the side of the compressor, Tucked up out of the way.

This is a work in progress, stay tuned

Nice work!  I've have a York sitting on the shelf for years that I wanted to use for OBA.  What did you use for input and output fittings?  I thought the York had proprietary fittings.  I assume you didn't have factory AC

I did have factory AC in my jeep at one point. When The frame was rebuilt, I cut most of it out. I needed the AC condenser real estate for the power steering cooler.

The factory york fittings were Roto-Lock.... Instead of running those, there is enough meat in the head to drill and tap for 3/8 pipe thread.

Kilby Ent. used to be a good source for fittings and push lock hose, don't think they are selling all the small parts anymore since they got bought out.

Kilby used to sell a replacement alternator pulley that had the factory serpentine and added a V-pulley on the end.  That way if the compressor ever seized, you could just pull the v-belt

Make your closed in frame the air tank. Locate air fittings around the corners of the Jeep and we all can air up at the same time.  :grinyes:

Even if the compressor seized, the clutch disengaged would allow the pulley to spin free... unless im missing something

7 CFM @ 170 PSI is going to be around 12 CFM @ 90 PSI

What are you going to use as a pressure switch?  Solid State (like the one ARB uses) or mechanical?  I have a mechanical pressure switch that switches 12V if you want to try it out

Tom - this pressure switch/unloader/ball valve assembly should mount up on one of your custom manifold ports...  It's an adjustable pressure switch.  You can have the 2.5 gallon tank too if you need it.  I built this set up a decade ago and had the Pep-Boys MV50 12V compressor on top of the tank  :mrgreen:

Coming home last night I was greeted by a large box from the rain forest. Amazon 2 day shipping has made life soo much simpler. Started by threading the aluminum block / installing the required fittings.

With the block mounted in place, I bent up some copper tubing. If you need to bed tubing, buy this bender

https://www.amazon.com/Imperial-Tube-Bender-16-Cap/dp/B007I9Q4RY

Test fitted the copper, and snugged it all up.

Against my previous plans, I will be running a small tank. sitting in work yesterday, I realized a paint ball tank will work perfectly! Becca and I went to walmart and bingo


Initial testing without tank. The setup works freaking sweet. If i hook up a blow gun on a section of coil hose, the compressor will pressurize to 120 then kick off. as soon as the trigger is pulled the compressor clutch kicks back on
