Thread: Engine driven compressor from aircon pump

I've fitted 15-20 York twin piston a/c compressors to various vehicles over the years to do air compressor duty. No to an Isuzu though. There is an oil passage from the inlet port to the front bearing housing that should be blocked for best performance. Take the head off and tap a small grub screw into the oil channel that's visible at the bottom of the port. Oil level can easily be checked in these compressors. 'Diesel Kiki' branded a/c compressors from the early 70's used to be good for this too.

Not hard to do at all if you are using the aircon compressor as an on board air compressor, All you have to do is add an air tank and lines. I have a 6X6 which already has aircon and I am in the process of adding a York piston compressor on top of the existing rotary aircon compressor bracket. I have yet to make a mounting plate for the compressor and it will be driven from a double pulley on the alternator. There is a lot more room around the 6X6 engine bay than a 4X4 but if you don't run aircon you should be right. I would post up pics if I had it finished but haven't got that far yet.

Would you recommend the york compressor to convert or the isuzu unit. I have noticed most tutorials around the place all mention the york compressor due to its high output I am guessing it has a much higher output than the isuzu unit would.
No point running aircon in a canvas top so plenty of space in my egine bay to mount one I think and getting rid of the arb unit will create even more space in there so I should be good.

Bee utey is probably the bloke that can answer that question the best but I can say that they are a very robust hi output twin piston compressor and if you can fit it in that's the compressor I would use - in fact I am

I have a York on my SIIa for compressed air. I also have a 240V driven York as my workshop compressor. I am happy with them both.

For near ten years I've run a standard disco 1 Dandenong rotary air con compressor as an air pump on my 300tdi. With a 130-90psi pressure switch thru the clutch wiring and a 20l air tank.
To ensure it has remained oiled and lubricated I simply have the air supply plumbed to the rocker cover. Nice filtered and oiled air supply.

Dandenong much more compact than a York and likely cheaper to source.

the main advantage of the original yorks are mainly traditional based things.

back in the day it was plentiful, easy to modify, easy to check the oil level in.

the ease of checking and topping up its oil being the only real remaining benefit of the york reciprocating style compressor vs other styles of compressor. and IMHO, this is outweighed by the ease of installation of other compressor layouts.

I'm interested if anyone with AC has also managed to fit a second compressor.. i'd love to do it but don't think there is the space.
