Ok guys here is the deal... I have been reading here and other places regarding onboard air... really which compressor to use.....

York - tons of write ups....
how to tell which one you have....

http://www.kilbyenterprises.com/york-manual/pdf/6.pdf
Mostly came on Volvo's some older model fords (some say early model 4cyl mustangs had Yorks with a serpentine belt set up) and AMC's

Cons- BIG hard to mount with out some fairly major DIY work... have to mount straight up... or strait side ways (sideways is up for debate it seems)


GM A6 Compressor......
don't know much about these..... so I guess my questions is what years did they come... how to get serpentine belt set up (did some come that way?.?.?) and why can't I seem to find any thing on them on this forum.?.?.?. other offroad forums say they are as good as Yorks.... and have a oiling system similar to the York so you do not have to run a oiler and oil separator.....

Any help?
 
Yorks rock. Period, end of topic. Anything else is second rate.

I *thought* the A6 was the Sanden, which requires external oiling.

Mounting is not bad. There are brackets available, both commercially and from a vendor/member here... Muddytazz, IIRC.

Serpentine belts can be challenging if you're cheap; it's easy if you throw $$at it (Kilby sells the stuff, but it's pricey.)

Search for any of my or 4x4High's threads about Yorks.

I run an A6. The brackets came stock on many years of k5 truck, from the early 70's through mid 80s they were used. Also called the 'log', they're 6-8" diameter, and almost a foot long. Internally oiled be a seperate reservoir, pumps just as quick as the yorks I've dealt with. MUCH easier to package.

Ahhh interesting. So the Sandens must be the new short-can ones ... is this the A6 in the bottom left?

Ok all you blender ****ers:blender:, here is the deal; I need to setup a high output a/c compressor, and an OBA setup for my airbag suspension.
Anyone have any info on how much gas these thing flow? I am sold on a York 210 for the OBA already, but I want your input. So far all I have found it York CFM outputs, and that "stock" a/c compressors suck ass. I tried work's AllData, but no flow ratings there ether. My electric compressor(550c Viair) is getting sold for various mounting related reasons. I could keep it, but It would run all the time to fill up the bags.
If a York flows more then the stock a/c compressor, Ill mount two up. Maybe a commercial bus style? Anyone have any numbers/websites to throw at me?

Tons of visual info for many types of A/C Compressors

**** Tons of info on a6 and Sadens Rebuilt stuff, gaskets, types, backing plates, TONS.

The other thing to note is that the York and A6 have an internal oil supply where as the rotary Sanden style do not and rely on the oil in the refrigerant (R-12 or R-134) for lube. Using a rotary style (Sanden) needs additional lubrication system of some kind. Oiler on the intake and a oil trap on the outlet with a return line to the intake for example.

Hmm, I wonder if the A6 would fit in place of the smog pump....

I keep thinking a York would go well there on my big block -- lots of room above it, so it oughta fit vertically.

OTOH, thinking is as far as I've gotten with it :haha:

JACK POT!!!!!

"Car air conditioning has been around since the 1940 Packard. One of the most recognized manufacturers, Frigidaire, has been manufacturing air conditioning components for automobiles since the early fifties. Their first successful complete air conditioning systems were installed in 1953 Cadillac, Oldsmobile and Buick cars. One of their more popular successes was the design of the model A-6 compressor, which was used by General Motors for more than 25 years. The A-6 was Frigidaire's first axial designed compressor. This compressor used a cast-iron cylinder and heads with a steel case and "swash" plate. The A-6 designation related to its axial design and the fact that it was a 6-cylinder compressor unit. The interior of the compressor also had an oil pickup and sump system to lubricate the internal parts. The A-6 compressor will push out 27,000 BTUs at 2,000 rpm and as high as 42,000 BTUs at 4,000 rpm with a discharge rate of 240 p.s.i. That's enough cold air to cool a small house (most home window-mounted air conditioners are only rated from 5,000 to 12,000 BTUs). The compressor functions much in the same way an engine does but without the ignition and combustion strokes. An A-6 is rated at 1.5-inch bore with a 1.2-inch stroke and 207cc displacement. That's about 121/2 cubic inches. The A-6 is also highly adaptable. It can run in 6, 12 or 24-volt systems if you install the proper clutch coil. They are a pretty resilient unit too; they can turn consistently at 6,500 rpm all day without overheating, and you can turn them in either direction and they will function in the same way. Originally designed to be used with R-12 Freon, modern adapter kits allow the A-6 to run on the newer, more environmentally friendly R-134a. By 1969, 54 percent of all new American production line cars were equipped with air conditioning. In addition to offering A/C as a factory option, most dealerships were installing aftermarket air conditioning at their own facilities using the A-6 compressor as the major component. By 1997, 96 percent of all new cars were factory-equipped with A/C.



If you are in need of an A-6 compressor, your list of donor vehicles includes:
1962-'84 Buick and (and 1985 Buick diesels)
1962-'79 Cadillac and Oldsmobile
1962-'81 Chevrolet (cars) and Pontiac
1962-'85 Chevrolet and GMC trucks
1972-'80 Ford
1971-'80 Lincoln
1974-'80 Mercury
1972-'85 Jaguar XJ6 and XJS
1978-'86 Audi 5000
1966-'85 Mercedes
1972-'82 Volvo


Although primarily used on GM vehicles from 1962-'85 and other cars from 1971 and up, you will find this compressor used in many off-road and heavy-duty truck applications, as well. Off-road applications include Massey-Ferguson, Allis Chalmers, Caterpillar and Deutz among many others.


Frigidaire compressors used in the above General Motors and import applications were activated by a high pressure or superheat switch located in the back of the compressor. Although these units look the same, there are slight differences in the size of the hole and its position on the back of the compressor for the switch........ Some 4WD enthusiasts have even built onboard air compressors for their off-road trucks using the A-6 as the primary source of pressure."

I think you could use a A6 in place of a smog pump... I am going to the junk yard very soon to grab one and see how she looks in the place of the smog... cross my fingers and I think it will work....


Oh yea... I think I deserve some kudo's for this :D
 
Maybe a cookie for now, kudos if it works. I think it's going to be to long for the air pump opening.
 
So, the big compressor I have in my 86 with the non-op AC could be converted to onboard air without the need for an oiling system?

How does a guy fill / empty the sump on the pump?
 
Went to my local "junk yard" yesterday and picked me up a "6A Frigidaire" from a 70's model Oldsmobile cutlass supreme..... and told the guy what I was looking for...

"oh yea we have been using one of those on the red wrecker for years... even run air tools with the wrecker idling"

it is a V belt but I am going to do my best to find a way to use a new style clutch serpentine belt set up..... I will keep you all posted....
 
How much did you get it for? I might look into doing this for the 88 Burb as I dont have the origianl AC anymore. Since I'll be junkyarding the project, I can hopefully find the brackets too.:D

Kinda funny you ask... my local "junk yard" guy and I are pretty tight.... my shop seems to get my friends stuff there and my stuff there and when I take a notion to clean up around there I usually take my old scrap metal over to his yard and dump it off.... for me it use to be the way to get rid of stuff.... since metal has went out the roof I have been saving up to take a load an hour down the road to where they pay you for it.... so with that said he gave it to me.... I have read that they usually go for $25 to $50..... good luck bro....

I will do the same tomorrow when I am at my shop to see what I can find out too.... also it has been discussed the posibility of sticking this where the air pump was..... not gonna happen..... now maybe relocate the alternator to there and put the A6 where the alternator was?.?.?. or maybe move my current AC compressor (which is not hocked up but will be very soon) down or something..... guess we will see.....
