I've seen the a/c comp conversions to air compressors for tires and such. My question is there anyone out there with both? Though its not charged and leaks, I hate to sacrifice my possible a/c but I don't really like the idea of more stress on my elec system w an electric comp.
With my smog pump gone, could you mount one there or having 2 comps on the 351 just too much? Obviously I wouldn't run my a/c wide open while I change tires, but to have them both on there and use one at a time.

 

Plenty of space on a 351. I have a York 210 driven from the steering pump by a combo serpentine/v-belt pulley. I was gonna make this pulley myself by welding two pulleys together but I couldn't find the right serpentine pulley. The factory one is plastic and of course I would need a steel one to start with. I bought my pulley from here:

Home

And of course they have the compressor mounting bracket too but I just made my own out of 3/16" steel instead of aluminum like theirs is. And I didn't like that hideous orange color either so I painted my pulley black.

I can still mount something where the smog pump would go as well. Don't think you'll get a York pump in there though. A Sanden pump is smaller and will probably fit but they require an external oiler for lubrication where the York has it's own crankcase.

Anyway here's my setup. Factory a/c compressor on the left, York air compressor on the right, steering pump in the center.

 

Did you bump your idle up with the quadrajet part? And when does your comp actually come on? Anytime your air press drops or on a toggle?

 

Nope, didn't have to touch the idle. The compressor barely loads the engine down! As of right now the only control is by pressure switch. It cuts on at around 100 PSI and cuts out at 130. I have plans to make a custom center console (or if not that, then an overhead console) and one of the controls on it will be a three position switch for the compressor. Positions are Manual/Off/Auto where Manual runs the compressor continuously and Auto allows it to run by the pressure switch. I had this on my old console but when I took that out the controls went with it so I have to get around to making a new one.

I'll take some more pics of my setup here in a bit...

 

Okay this is an old pic. Mounted some controls on a spare console top that I had to see if I liked having them between the seats. That console went back to stock for now and the controls are gone (that digital display is now mounted in the dash) until I fab a custom console up to do this right.

 

Here's some more pics...

Compressor charges this 8 gallon tank thru the oil/water separator you see in the lower left. Bought a brand new compressor and robbed it's tank cause the ones that are sold for building your own on board air systems usually have like ten ports on them and I like to keep it simple. After the oil/water separator is a brass check valve with an unloader port. The black tube you see coming from the side of the check valve runs to the unloader valve on the pressure switch. The 1/2" solenoid valve feeds the air horns under the truck. The orange hose off to the right is to the quick connect air fitting on the outside of the toolbox.





So I can run air tools! The picture don't show it but the end of the air fitting is actually flush with the top edge of the toolbox so the fitting is pretty well protected.





These are useful during snowbird season and for all them folks that think they're the only ones on the road.

 

Great info. Thanks for the pics. From my math my new rear bumper should hold ~ 9gal. .

 

460. . can u get me the model number off your York.just 210 came up a lot of different ones

 

I can't, I bought it from a rebuilder and it's missing it's nameplate. I can tell you that it's a 210L which means it's a 2 cylinder, 10 cubic inch, left hand discharge.

There are 7, 9, and 10 cubic inch models out there with model numbers 207, 209, and 210 respectively. Here's how to tell which one you have by looking at the crankshaft:

Then you have your choice of right or left discharge. This is just the location of the suction vs discharge ports... they are both on top of the compressor, it's just that you can have them either way around depending on which compressor you buy. It doesn't matter one bit if you mount it right side up like I did, but if you're gonna mount the compressor sideways then it DOES matter. I think because the suction port has to be above the discharge port.

And the last thing is the connection type for the suction and discharge ports. There are several and not one of them are NPT thread. Mine were flange style so I just had one of the pipe welders at work TIG a couple 3/8" street elbows to some flat stock, and I bolted them on. I can take pics of this if you need.

Here'a a rebuilt 210 with the flange-type connections on top: http://www.ebay.com/itm/73-84-VOLVO-240-260-YORK-210-A-C-COMPRESSOR-FREE-OIL-/121192061059?pt=Motors_Car_Truck_Parts_Accessories&hash=item1c379c1883&vxp=mtr
That will work for what you want if you can fab up the fittings to go on top. Or you can buy them here but I wasn't fixin to shell out $45 for a pair of fittings I could make for less than $5 http://www.kilbystore.com/28723.html

Oh and also... you CAN run both the a/c and air compressor at the same time. Not sure why you thought otherwise but it ain't gonna hurt a thing.

 

How did you attach the second pulley on the crankshaft. I'm digging the setup though

 

Did you not read post #2?? The second sentence says: " I have a York 210 driven from the steering pump by a combo serpentine/v-belt pulley."

He even goes on to tell you where you can buy said pulley....
