On Board Air compressor

[eagle mark]

I've got a 1990 Blazer but I think the motor was changed as it has a v belt pulley on the crank which was supposed to be used for the air pump in earlier years. Everything else is serpentine.

Air pump is gone and I was planning on using the v belt pulley to a York compressor. Question is has anyone tried to mount a sandon (sp) compressor back in the spot where the air pump came out of?

im sure its do able but youll have to make an external oiler since the sandon pump is not like a york the freeon lubes the pump in a sandon the york is internal oiled with 80w90 gear oil.

Yes I realized I would need and oiler and seperator but it seems that may be easier than making brackets for the York to run off the v-belt.

I've also thought of making a super duty viair type compresor with a york compresor and a starter motor...

Keep in mind that the V belt for a smog pump is usually a pretty narrow belt and you will not find a pulley for any AC compressor that is that narrow.

Well you just rained on my parade...

Sugestions?

Either buy the Kilby mounting bracket kit for the York or build your own and run a York. I opted to just buy the bracket kit and leave all that guess work to someone else, of course when i bought mine it wasn't GOLD pricing like today and it also came with the belt which i believe now they don't.

Contact Buefchris here on CK5> IIRC, he has a York setup but is not engine driven but electric motor driven and works pretty well. Just a thought.

Starter motor will only turn it for a little while. They aren't meant to run anywhere near 100% duty cycle that you would need to produce any real air volume.

I realize that but that is turning an engine. The load would be much less turning just an A/C compressor.

After looking around I remeber where I got the idea for a starter attached to a york compressor.

That's a winch motor, not a starter ... very different duty cycle, very different design.

You're losing efficient converting the rotation of the gas motor to electrical energy in the alternator, and converting it back to movement with the electric motor driving the York. Obviously you'd be better off just running the York directly from the (gas) motor if at all possible.

Well, yeah but you're not losing much in efficiency. Electrical components (both alternators and motors) are pretty efficient, say 90% as a low figure. The motor is 2.5 hp, so you're only losing a couple tenths of 1 hp in efficiency losses.

As for duty cycle, the York is 100% duty cycle while the electric one posted is only 30%. That could certainly be relevant based on what you want to use it for, but it sounds like it can move an awful lot of air.

And the benefit of mounting it wherever you want is pretty sweet too.

Each has its place and each will fill up tires just fine. If you want to run air tools off of the compressor it might be a better idea to use the York.

Well, a York is 100% duty cycle no matter what ... it was the winch motor that was limited to 30%

And under the hood of a fullsize, Yorks don't take a lot of space.

(That said I still haven't sorted out where to put one on my bigblock ... but hey, a man needs projects )
