Cool York OBA Question!

Hey everyone! Finally came time for getting a OBA and I have decided on the York belt driven compressor. So far the crucial parts that I have found out that I will need is, the unit, kilbys bracket kit and the clutch assembly. I will be heading to a couple junkyards tomorrow to find the compressor.

Should I be looking for a specific model or will any do? Also did they come stock with a 6 tooth pulley?

Thanks!

Not sure about the 6 tooth pulley, whatever that means, but the model York you want is an F210. The '10' meaning it has 10 cubic inches which produces the most air. I paid $30 for mine years ago.

I bought my York at a junkyard that had 12-15 of them on the shelves and used a 12v car battery to test 4-5 of the best looking ones to pick the one that had the most suction/pressure when I spun the pulley by hand. Place your hand against the suction/output lines to tell.

The below shows how to identify the York's capacity/model.

By the way, a flange head fitting style is highly desirable. Kilby has flange head style fittings that make connecting that style intake and output fittings easy. I'm talking about the intake and output line fitting style, not the head itself... i.e. two bolts holds each of the two fittings onto the head.

I see that kilby doesn't have a mounting bracket for a 2.4L.

Found exactly the one I was looking for! F210R and has the fitting with two bolts that Jerry mentioned! Spun it with a tool and it has good suction and pressure. Ill post some pictures after I clean it up. Had to pull it out of a 78 ford. I did find 3 but this seemed to be in the best condition.

Wow nice find, what'd you end up paying for it? Prices have probably gone up from the $30 I paid for mine 12-13 years ago.

Question Jerry since you have owned a York. How do you oil it and what kind of oil? Also how do I hook up the suction and the output? Im gussing output goes to a tank and the suction is left open?
Thanks

Use 30w oil, fill it from the side where the little hex-head bolt plug is. I connected the suction to a rubber tube I connected to a fitting I added to the air intake tube. Go to Lowes or Home Depot to get some brass barbed fittings that will screw into the new bolt-on manifold you can get from Brad Kilby. I inserted a brass barbed fitting into the air intake tube for the compressor's air intake, held on with a nut inside the air tube.

You can kinda see the air intake hose where it connects to the air tube, right in the middle of that sticker. Connecting it to the air intake tube means it gets filtered air without needing an additional air filter.

I like that setup, did you buy that pulley that connects to the alternator aftermarket or did you have it custom made?

EDIT: Also the York came with its own clutch, I just tested it with a 12v current and it works perfectly.

Kilby sold me the dual-pulley for the alternator, I liked doing it that way better than converting the York to run off the serpentine belt.

Il check his site out and see if he has any for sale, maybe give them a call if I dont find it. I looked deeper into the bracket and I dont want to relocate everything around and that setup you have is perfect.

Found the dual pulley on kilbys site for $65, not a bad price for a custom piece. Thanks for your help Jerry, you made this project a whole lot easier

An air impact wrench will make getting that pulley nut off a whole lot easier.

Well, I guess im just going to make this a project page for installing the York compressor. Ill provide pictures soon, projects been on hold because crappy ebay radiator started to leak after one month, and the guy is giving me the run around for a replacment.

Whats been done since last post.

Kilby Combo Pulley arrived and installed (pic to come)

York Clutch bearing was toast, ordered a new one and installed it today(pic to come)

Thought out some ideas on a custom bracket. Bracket will be fabricated around tuseday my dad can weld and I cannot. (Need to learn to weld correctly).

Heres a picture of the engine bay. The empty spot is where we are going to put the custom bracket with the alternator on the bottom and the york on the top.



Heres is a picture of the alternator pulley. Kilby Enterprises makes the combo pulley for around $65.

Link to pulley. ::Kilby Enterprises::



Bought a new bearing for the York clutch. Old one would make a click noise when turning. Bought the bearing off ebay.

Bearing Size of stock two V-groove: 6206 Z





For anyone thats going to be doing this in the future. Kilby sells their own custom bracket kits on their site. Kit includes their bracket and a longer serpetine belt to accodomate the york clutch.

Link to brackets: ::Kilby Enterprises::


The reason I didnt do it with the kilby bracket is because, I already had a working V groove york clutch. a 6 groove clutch would cost around $80, so why spend the extra when you already got a working one. Also, I would get to keep my original belt pattern.

Finished installing the York! The whole fabrication of the custom bracket, to the belt placement took only one and a half days to finish.



Here is a side shot of the whole thing and how it looks before the belts. The belt pattern stayed the same, except that the alternator got lowered a little.

We took the stock belt tensioner out and replaced it with a Jaguar tensioner bracket(Long bolt sticking towards camera) thing found at a junkyard, which works perfectly at keeping the belt tight for our application.




The custom bracket has reinforcing arms that extend from the bottom towards the side of the engine block, heres a sideways picture of one of the brackets.




The whole thing assembled with the custom made bracket gave us enough room for the stock airbox, and it sat the york about inches away from various radiator hoses and the fan. It was like the york was ment to be installed right at that spot.



I forgot to snap a picture of the bracket itself, probably do that later on if I ever take it off.




Also went to my local auto store about 10 times switching out belts because they were either too long or too short before finally finding the perfect size V belt and 6 groove belt

Nice job, especially that you mounted it in such a way that you're still able to use the factory air intake box. I had to remove my air intake box to clear my York compressor that was mounted using Kilby's mounting bracket.

Thank! wasn't expecting the stock airbox to fit but after finishing it all up and trying it out it amazed me. We "accidently" made it fit.

After a long time, I managed to complete the york oba system. I haven't tested it on my tires yet but just watching it fill up the 2 gallon air tank to 130 psi at idle amazes me. From start to finish it cost me ~$650 and some fsbrication.

Made two hose connection ports, one in the front and back for airing up or for power tools.

Pressure switch turns on at 90 psi and turns off at 120. Saftey valve is directly on the tank and is set at 160 psi. 2 gaugss, one in the hood on the manifold, and another on top of the dash. 2 switches, one to turn the presure switch on/off and the other for the air horns.

Was a great learning experience, went to my local hardwaare store at least 8 times to get tje right fittings. Also thanks to Jerry for helping make this project a lot easier!

Hi, I just came across your thread, and I am also new this the forum. I am on other forums and not new to jeeps. I have in my tj a York oba. I have been working on trying to figure out tank size and placement. Where you have your tank is where I was thinking myself. What size is the tank you used?

A 2.5 gallon air tank worked perfectly for the York OBA system I had in my previous TJ. I mounted it underneath between the rear driveshaft and frame, right next to the frame. Though my TJ was a rock crawler, that position was protected well enough from the rocks that even though I had gouges and scratches everywhere else under the Jeep, the air tank was never touched the 9-10 years it was installed before that TJ was stolen 5 years ago.
