OBA with York - NOT engine driven...

[Justin.Hutch]

Yet another superduty on board air project. EXCEPT I'm not hooking mine up to the serpentine drive. Instead its mated to a 12v winch motor. I'm putting this short thread together not as a write up, but to give people more ideas since OBA questions constantly come up.

Little parts list I have
*York and winch motor - Check!
*Air tanks - Two 3gallon tanks from ebay
*Winch solenoid - Ford brand from autozone
*120psi pressure switch - 90 on 120 off...Check
*water oil seperator - 3/8" inline...Check
*Check valve with unloader - Local truck parts place
*Various lines and fittings - Lowes is real close



I will be mounting everything on the outside of the frame rail. I have a long bed so LOTS of room

Got the winch and compressor mounted...



I also have the tanks mounted, along with my new horn but no pics yet. Should have them up tmrw.

What kind of duty cycle does that winch motor have?

Cool project. I like your truck by the way.

I'm not sure on the duty cycle, but here is a link to pretty much the same winch that I used the motor off of.

I decided to mounth the tanks underneather the bed in between the outside of the frame and fender well, right in front of the passenger rear tire...



I used 1/2" heater hose from napa that goes straight from the compressor, to my check valve with unloader, then into the tank. A lot of people say to use steel braided line or copper tubing since rubber hose will melt, but the hose has handled it so far.

Originally I had a 145psi pressure switch I was gonna use, but do to a wiring malfunction, I fried it a long with my toggle Another change I made was the warn solenoid I planned on using. The Warn solenoids are setup to use 2 solenoids for power, so instead I went to autozone and got a standard ford solenoid. Now I run a 120psi pressure switch with it.

My outputs on the tanks are 3/8", so I went and ebay and bought a "3/8 12v solenoid" for $30 and mounted it to one output and ran an air line to the exact opposite side, which is where my horn was mounted.


So far everything works great. I hit 120 psi from Zero in MAYBE a minute, probably more like 50sec.

Very cool. Looks good.

It's been a few months, I know but do you hear the motor kick in and how did you mate the shafts up? I have a york long stroke and was figuring on mounting in the engine bay....Trying to figure the best way to mount this up is a little bit of a PITA.

How is the system holding up?

[Justin.Hutch]

It works awesome. Only problem is, that I never use it for what it was initially intended for. All I do is blast the horn!. I put air fittings and it airs up tires very very easily. I have 44" swampers on my Jeep and it airs them up no problem.
