York system, (update post #122)

[readymix]

I finished plumbing the system up to the manifold.
Now all I need is the rest of the cheap 3/8" rubber hose to the tank and get the tank mounted.

Anyone know about how long the york should take to get a approx. 11 gal tank up to 140Psi?

I ran the system while filling up the tank through a jumper hose and all worked well at first.....not so much anymore.

The check valve/relieve valve seems to not be functioning correctly.
Normally it will allow the air to go to the tank at full flow until the pressure switch opens, then it dumps all the pressure between it and the york.

This evening it was venting air stating at about 50-60 PSI and up. This causes the tank to never fill above about 100 PSI. If I rev the engine the valve seems to open all the way and works correctly until the cycle starts over again.

My thoughts:
1. The valve might just be going bad. I did take it apart to clean it and found nothing wrong.
2. The clutch on the york may not be engaging fully, and not pushing enough air to force the valve all the way open. That would explain why the valve starts working if I rev the engine.

Any other views on this one. I am lost at this point.

The output on the York is a function of its speed, which is related to which clutch pulley size it has (there are at least two) and the pulley you're driving it from. I have mine (with the smaller pulley, which spins it faster) driven from the main pulley and the steering pump.

You might bypass the check valve, just as a quickie test, but IIRC without it the compressor works really hard to charge the tank, and may not go above 100psi at all. If you were local I'd loan you mine as a test =))

I seem to recall that my York will charge the ~10 gallon tank up to 150 psi in a minute or two, it's very quick.

HTH.

Finally had a chance to clock my York. At 1500RPM (fast idle -- I put a manual switch onto the AC solenoid) it'll charge my ~10 gallon tank to 130psi in about a minute forty-five. Obviously that's with no load (i.e. no impact running =)) but it gives you an idea of what should come out of the York.

Cool, thanks for the info.
I still have not had time to play with it anymore. Work has me far too busy.

If the intake has a 3 way valve connected it with 1 side going open filter to pull in air, and the other is an attached line of hose, how much vacuum do you guys think a york could pull safely without damaging it?

Donno 'bout damaging it -- it's not like it's a fluid pump that you're running air through. As long as you keep it lubed, i.e. keep oil in the crankcase, I don't see how pumping with it would damage it.

I cannot immediately visualize what this three-way thing is, though; I assume you don't mean a manifold or a splitter?

And what the heck do you want that much vacuum for?

well what I had meant about a 3 way valve, is a valve you can choose between leaving the line open for compressing air, kinda like a T, or closing the filter off and opening it up to a sealed line to create vacuum instead of pulling in fresh air. I am rolling this around in my head for a cheap way to power my wvo tank. Creating a vacuum of say around 15-20 lbs inside a properly sized container and a 2" sucker hose(lol...i know), can empty a 55 gallon drum in a minute or less. Then when I get wherever I need to empty it, just apply some positive pressure and a little heat to power it out through some filters. This way, it will avoid expensive pumps that will wear out and just cost more money...

As long as you never suck fluid into the York... I s'pose.

Basically, a York is a little two-cylinder engine, only instead of expanding gas+air inside and blowing it out as waste to spin the crank, you spin the crank to *compress* air and blow it out as the end product.

Point being that, just like your gas motor, fluids do NOT compress well and you could hydrolock the poor thing, or at least gunk it up so bad you have a paperweight that smells like french fries.

OTOH, a LOT of the WVO stuff is the DIY spirit, and NOTHING says Redneck Ingenuity like having an engine-driven air compressor under your hood... so I'd say go for it, and worst case, carry a spare York in your toolbox

Yeah I definitely wouldnt want to suck oil up into the pump, I would be using it for the sole purpose of creating a vacuum. I guess it would be good to have a small quick disconnect and shut off valve at the tank to make sure nothing travels up the line anywhere down the road. Yeah pushing oil through a york would be a big no no. lol.
