View Full Version : York OBA build

Just went to the junkyard and snagged a York 210 compressor for onboard air. I know that this has been documented at length elsewhere, but I figure I might be able to get some advice during the build, assuming others might have already been through this. Its going on to a Chevy 4.3 V6, but really this should be an engine-agnostic project.

BTW, I *believe* AA Auto Parts has more of these for $25 right now, in case others are interested.

So far I've ordered a serpentine style clutch, a coalescing filter and a 160 psi gauge. I'm thinking, right now, that I'll try my hand at building my own bracket (my second welding project!). I thought about purchasing a kit, but the York I found has the discharge on the wrong side and I'm stuck mounting it upright. And its a nice challenge. This is what I'm trying to duplicate: http://www.pirate4x4.com/forum/toyota-truck-4runner/579496-york-air-4-3l-powered-first-gen.html

On that note, does anyone know where I can get some 1/4" plate cut? I might be able to use my cutoff wheel, but I'm thinking a plasma cutter could be a better tool for the job.

Dave done a fair bit of metal work. Maybe he has one or knows who could help you out.

Good plan! Once the new clutch gets here I plan on making some cardboard templates, and will talk to Dave. After all the work that went in to the trailer, I'm sure he knows how, or where, to get metal cut. :cheers:

I just finished this project on my 80, so some of the details are relatively fresh in my mind. The biggest pain for me was all the various fittings and connections, and figuring out exactly what you need. I ended up with about $50 in extra brass that I don't need....

What's your plan for integrating into the fan belt/pulley?

drill and tap the head to accept pipe thread street elbows. done. that's what i did...

looks like you have the perfect compressor for it

Ok, went and used a drill-mounted steel brush to clean (most of) the grime off, and got a new 6 groove clutch installed.

I'm already collecting bits I don't need, or worse - getting fittings that require other fittings when one would have done the trick. Its not all that bad though - I just figured I would sit down and seriously think through the setup at home and order it online. I'm paying extra for shipping but I can process this stuff better when I'm not in a store/in a rush to get out. On the 4.3 there is just one serpentine belt and an idling pulley where the original AC would have been. I'm removing the idler, tensioner, and all of the bracketry that holds it and making my own bracket to accommodate both the compressor and the tensioner. Pretty much the same thing that was done in the link I posted earlier, just with my pump mounted vertically.

That was my thought too... I got a 3/8 tap - what size did you use? I'm wondering if I really have to drill it first and if so, what size bit I should use. I might also just tap the original fittings. Would hate to have to find a new head for it. (or new compressor, more likely)

I think I used 3/8" and I don't remember if I drilled it or not. I seem to remember the holes being pretty decent sized... Drill bit for a 3/8" NPT tap is 9/16"

Don't worry about messing it up.. If you are worried about it I can help. Even if the holes are too big the tapered tap works great and you can get some decent threads in there. I used anaerobic sealant on them also.

Nice thing about tapping it also was that I was able to use the elbows which kept it really low profile.

Here is my thread on it:

looks like i did use 3/8" pipe threads in it. there are a few pictures in the thread.

Thanks for the info - I'll give it a shot, maybe with practice on the stock fittings first. Nice looking setup btw. Great that you were able to find a stainless compressor! I'm going to try and get it hooked up to a tank sooner than later, hopefully that will reduce the load on the York. I do have a tube bumper...

Thanks for the link! I have been kicking around adding oba to my 80 with the 5.3l but the mounting bracket had me stumped.

I have a 14" chop saw I used to cut my tubing and a 4" angle grinder for the smaller stuff both of which could work depending on what size you're starting with. My sheet metal was cut to size so I didn't need to do more than a few trims there. You're welcome to what I have though.

Thanks Dave! Made a mockup today and think I might be able to get by with a chop saw... We'll see. I'll do what I can here and might ask for some of your expertise. Here's the mockup I made (redneck solution):

Also, the manifold/filter setup is complete. Just need a couple female disconnects (and a tank... but that might come later).

I'm kicking myself for not getting metal today. Dencol is closed on weekends, and I happen to have this one unexpectedly free due to the heavy rain. :-/

K & K Surplus on Brighton Road in Commerce City is open Saturday mornings and sell small pieces at pretty cheap prices. You just need to snoop around the yard to find what you need.

I was hoping you might have another option in mind... I'll be there!

Thanks again Dave for pointing me to K & K. Was cheap and quick and had what I needed. Just had to brush off a little rust (Gee, I wonder why everything was so rusty?)

Anyway, spent AGES with the cutoff wheel cutting plate. Definitely not the right tool for the job, at least if time is any concern whatsoever. But I got there. Bracket is probably halfway done, but good enough to tack it together:

And bolt it together:

Looks like it might actually work out! Belt seems to line up OK, so I wont bother slotting the bolt holes to make the compressor adjustable (this makes me happy). Got the fancy car occupying the garage while its raining, otherwise I'd still be out there. Hopefully tomorrow I can get the tensioner on and be back in business.

WOW! Glad K&K worked out. :beer::beer::beer: It's lookin' real nice Dan!

Yeah, 4"-4 1/2" cut-off wheels aren't real efficient, but they usually get the job done...in time. I'll tell ya about trimming my 2x4 solid steel front bumper on my 40 with 4" cut-off wheels (yes...plural) when we're on the Outlaw Run. :rolleyes:

Thanks Dave! This was with a 14" cutoff wheel... SO SLOOOW. I don't know if I can hear your story about that solid metal without hurting myself ;) Anyway I did some reading and heard that a sawzall works great, and sure enough it does... Cuts aren't as clean, but if you use another piece of metal as a guide you can make some decent straight lines. It went MUCH faster.

So I was able to get the idler mount built with some trial and error. Glad I tacked everything first because I had to break, grind and re-weld things several times before I got it. Still need to get some hardware to bolt it together, but the bracket is complete:

I'll get some photos of the completed bracket when I feel like looking at it again :)
