Yes, I bought it on Ebay. Of course, I need to replace it with a new/reman unit as the york failed while at Rausch two years ago.

CO2 is a great backup and even after I install a York, I'll still carry my 10gal PowerTank. It's not perfect, though. The tank does not go as far in cold weather and always seems to run dry when you need it most. It's also not suitable for high-volume uses, like blowing dust out of your truck. You'll empty the tank in no time with a blower attachment. The York, on the other hand, is like one of those tankless water heaters; it's basically limitless.

Almost all of the ones I've seen done so far removed the AC or were for a diesel. I started on this conversion for my Disco, so this would really only apply to 97 4.0 Defender owners, but I'm pretty sure I'll be able to retain AC. The only major alteration should be custom AC lines. The plan is a belt from a 2004 Disco with ACE, 1 additional idler, the SC york 209 (about 1" smaller in all directions compared to a regular york), and a custom bracket

Your 95 should be easier to modify since it is V-belt. Lots more options in mounting locations, though if it were mine I'd probably put a disco belt setup on it and 97 defender hoses to simplify things.
Haven't touched it in a while, been too cold out around here

Thanks guys for all of the input. This should keep me busy for a while. As an FYI, I am probably just going to rely on my old wrenches for tools, but I am really looking for a souce of air for my tires when done wheeling. I also plan to install a winch soon.

To Robertf:

I don't know about the 209 since you say it's smaller but I know with the 210 I used you are going to want to cut out your hood brace and use spacers to raise the pump a little so it doesn't rub the coolant tank. You can also trim up the tank bracket to bring it closer to the side of the engine bay.

I tried using a junk aftermarket coolant res but I blew out the connection for the line at the bottom and left me walking on the side of the interstate one particularly cold night. Coincidently I trace this as the very moment my wife began to hate land rovers

Sorry to hear it but many of us have suffered a similar fate. Several of whom are now divorced...
Raub has a great signature line that expresses his feelings.

I second the opinion that you want two sources.

Does anyone know what brackets are needed to install a York in place of the AC on a 3.9 serp belt engine? I have a York sitting on the garage floor taunting me.

Agreed on multiple sources...my two (or three) sources are:
1) Huff pimp-mobile
2) Galpin CO2
3) Rausch shed air hose

Not sure on the York bracket - BUT if you need a guinea pig I say we throw that York my way and get my onboard air back up and running .

After many good recommendations, I have decided you guys are much more sophisticated than me. I really am only using this for tires, not tools, or a locker, and I do not get off-road as much as I would like, so I really wanted a tankless setup. After a trip to 4wheelparts, it lools like the ARB dual air system may work but dang is it expensive. I am debating it now.

FYI on CO2. We use it for flats on MTB's and Road Bikes (the BB gun style), and it does not have the same air holding charactoristics as a true air pump. I find it will drop pressure pretty quick after a flat. Wonder if the truck tire volumn creates the same issue?

If you want to go electric, get a Viair 400H, http://www.viaircorp.com/400H.html Great bang for the buck.

CO2's only issue is that its critical temperature lies at 87.8 degrees Fahrenheit.

I'm assuming that your road bike tires are being inflated past the triple point of CO2 at 75 psi absolute. Above that pressure, the proportion of CO2 that is liquid vs vapor is not stable. Temperature changes can cause large, non-linear changes in CO2 gas volume at above the triple point.

Below the triple point, CO2 only exists as a gas (or solid), and therefore would follow standard ideal gas calculations for temperature vs volume that normal air or nitrogen would.

I think you've been watching too much breaking bad

a couple of shakes of the co2 tank is all it usually takes to get it moving again.

I've used my C02 in cold weather. Still works just fine.

If you get crappy C02 (aka, from the paintball shop) it'll freeze up the regulator. That'll cause issues for you.

I just took some card board and made a little model then took it to the fabricator. I probably jumped the gun because all that I really got back was a piece of 8"x3/16" strap bent around then a triangle welded between it.

I made essentially the same thing myself to use as brackets for the under tub bar on my 90 Rollcage. Just used a torch and a big hammer. The hardest part is getting the angle right for the bend and getting your holes to line up.

Also, I can't remember which one it is but make sure you get the model York with the oil return on the bottom side. I had to buy a second compressor because my first one was wrong.

It looks like you are going to have the same crunch with the coolant res that I had. Make sure you either move the stock res or find a good thick replacement. It will take a while but if the York touches your coolant res it will eventually rub enough for it to blow.

Yeah I'll make my own brackets, but figured it couldn't hurt to ask in case someone has them already. Thanks though.
