Question about York compressors

[Craig]

I've decided to go with a York a/c to be used as a pump vs a stock YJ a/c unit. I'm gonna buy the mounting brackets from onboardair.com. Just wondering if there's different models of York compressors out in the wrecking yards and if so which ones are better? What vehciles should I look at to take a York from? Newer or older better?
Also...wondering if it's possible to use the York for it's intended purpose of air conditioning and also use it as an air pump? Is it possible to install a switch (on the dashboard) controlled valve that'll allow the York to pump air either into the vehicle for air conditioning or to an air tank to be used for filling tires and eventually air lockers? It would be nice to be able to use it for both. I could just switch between a/c or pump. I know if it can be done it'll be pumping cold air to the air tank and to the lockers but I don't think that'll do any harm.

no.... a/c and compressed air are completely different.... the a/c compresses refrigerant around in a continuous cycle.. when it compresses.. the temperature increases tremendously... then when it is given a chance to decompress, the temperature drops tremendously... and ambient air is blown across that and cooled from the evaporating refrigerant inside the evaporator... the compressor doesn't deal with compressing cold air at all.... though..
when yu use it as an air compressor... you are taking ambient air and compressing it for use or storage, and not in a continuous cycle like with the a/c

[Craig]

Ok, so scratch that idea, looks like I'll just be using it as a compressor then. So what's the best vehicle to strip a York from? Is there different York's out there?

There are three different displacements to choose from, 6, 9, and 10 c.i.
You can find them in fords and AMCs in the junkyardsfor cheap.

Here is a good link: www.n2jeepn.com
also go to www.pirate4x4.com and do a search in their bulletin board.

haha.. nope, not the most advanced in that trade.... but i can work my way around most trades

i got a question about compressor ID. i bought a york a couple of months ago and the part & serial number doenst make any sense. the serial is "M 123612" and the part is "AMC 5461585" i was checking out onboardair.com for the ID and the number seem to be different. it is an AMC compressor made in july 1987. i was wondering if someone knew how the tell what the displacement is from these numbers.

[jps4jeep]

Here you go people, If your compressor still has a metal York ID tag bolted to the front of it, Which is rare cause they seam to fall off, there will be a number on the tag that looks like "F2XXY", where:
XX Stroke length
10 = long
09 = medium
07 = short
Y Discharge Direction
L = left
R = right

Like F210L is on the tag on my york. That is also how they get there names, 210, 209, 207.

Should the tag be missing, or you have a rebuilt model

Take off the clutch and look at the crankshaft.
Remove the center bolt (1/2" socket)
Remove the large washer
Run a 5/8" coarse thread bolt in until it forces the clutch off
Look at the end of the crankshaft. The end is flat on all models.
If the edge of the flat end is beveled, you've got the short stroke.
If it's a sharp corner, but with a thin groove for a retaining clip, you've got the medium stroke.
If it's a sharp corner without any groove, you've got the long stroke.

Hope this helps guys!!

I was looking around the sites you people posted and it seems the long stroke Yorks are most common in early 80's Volvos. Anyone know of a newer, more common vehicle to strip a long stroke from? Were they standard as long strokes in any other more available vehicles? I called around and there doesn't seem to be too many early 80's Volvo's around. I wanna get the long stroke but it seems most of the id tags are missing and the wrecking yards aren't too keen on people pulling the units apart to check the crankshaft. I'm gonna search around the web but any help would be great. Thanks.

JPS, thats what ive found everywhere ive looked, but what do you think of my numbers(earlier post)? the tag says york on it, do you think it could be rebuilt?? it had a lot of engine gunk on it and looked like it was original. do you know if they used that number configuration for all yorks??

[Craig]

One last question about the compressor. I've heard the freeon (however you spell it) is very dangerous to breathe in. When I pull one from a vehicle and disconnect the hoses am I gonna get a face full of the stuff? How do you empty the stuff out of the compressor? Also, back to my previous question...any more common vehicles than Volvos with the long stroke Yorks out there?

[Snitty]

if you know of someone with a recharge kit... get the hose from it... screw it on the port and walk away... do this in an open area... go back to the vehicle in about 10 minutes... you'll be just fine... i've let them out with me standing right there... not good to do though

[White]

I can't admit to breathing it all the time, But trust me Iam still normal....
I think

Do us the favor, Its so cold out I think we need to open up the ozone layer a little more .....

I was looking at the #'s on your york Joe, is that the original tag. Those might be a motorcraft rebuild. even if it was never removed from the vehicle, if it was a dealer installed AC system, often they used motorcraft Yorks. For example, my 77 has been family owned since it was bought at the dealership in 76, my old man had AC installed at the dealership, it is a york, never been removed, but it has motorcraft tagging on it.

I am unsure on how to read the motorcraft tagging, try to get in touch with them and see if they can enlighten you. also try the other method of looking at the crankshaft.

Late 80's taurus's have short stroke yorks
Older volvo's Mines off a 84 240
4&6 cyl stangs up to 88 I think.
Lots of vehicles with aftermarket A/C
Any AMC concord, eagle and a-like have 210's in them.
I have seen one in a older saab
I think the turbo diesels benz's from the late 70's till the mid 80's

Look like this



That is the bad boy in my YJ just after I got it back from the rebuild.

[jeeperjoe]

my tag says york automotive, i think it came out of some kind of eagle. the tag says '87 and it wasnt rebuilt since then. it might have been a dealer install. it doesnt realy matter what kind it is, im still gonna use it. i would take the clutch off and look manually, but i need one of them funky weird wrenches.
yours looks real nice JPS, if i find that mine has a long stroke, where could i have it rebuilt and how much?? oh, and did you use the factory hose fittings?? i have the hoses, but i would rather use new fittings.

[LGR]

does it matter what side the discharge side is when mounting it in the jeep? go for left or right?

[Snitty]

it won't really matter where the discharge is... the important part is to make sure it is mounted correctly, and is perfectly lined up

[Craig]

Ok...another question...hopefully the last. After I install the York and run it to the air tank what kind of valve do I need and how does it hook up?
I'm guessing some kind of 12 volt regulator valve. Does the wire coming off the York that engages the clutch run through this valve and to the battery to disengage the clutch when the tank reaches a certain psi? Is there a specific name for this valve? I'm planning on doing it hopefully this weekend so I need all the info I can get.
And what's this about a special wrench? I've read lots about getting the York and how to id it by the crankshaft and nothing mentions a special wrench. Anything else you think I need to know? Thanks.

[LGR]

i was looking into all that stuff on onboardair.com and other websites to help me learn better. onboardair.com has a nice map or layout of how to hook up your compressor and all the accessories in the FAQs section. http://www.onboardair.com/oba_sc.htm also the links section as other peoples instructions with very clear pictures(very helpful). Not to mention you can buy everything you need from them. hopfully that helps..i'm still new to this york compressor thing too...but well on my way common summer!
