running york oba air pressure to 150 psi

[haryv]

I had to take my bracket out again, to re-weld the cracks on it. Fun fun.

Anyway, I am at the last and long delayed stage of putting everything together.

I want to know if the york can run up to 150 psi , shut off to 110 psi, then restart again without doing any possible long term damage to the pump.

I have a regulator that will regulate the output to 100-110 psi for the hand tools.

I will have to make a bracket for my brass for way manifold. It is shaped like a PLUS symbol with air going in one side, and out the top for the pressure switch, out the there side for the tank, and out the bottom to route a line to the front of the truck.

I also need brackets to mount to the truck body. This will hold the female air hose chuck.

Any one know of local suppliers in Vancouver that has these brackets would be appriciated if you can tell me who these distributors are.

you can run it at 150psi but it'll reduce your life expectancy and create a lot more heat. keeping them at 110-120 is a safer bet.

has anyone adapted one of the semi-truck air tanks to use with a York compressor or other onboard air setup that jsut uses teh compressor itself? Just wondering....seemed like a good idea?

Howdy! I have been running a York OBA system for nearly 10 years. It includes a 3 gallon tank stashed behind the front bumper. I run it at 90-120. If i crank it up higher, it causes the drive belt to vibrate a bit. When it goes up around 150+ the belt starts to get pretty slappy on the return side. I also am using a regulator that has a dead bleeder port. When it reaches 120 and shuts off the clutch, it also releases the pressure on the head side of the regulator so it does not leave the compressor pressurized. My York is vintage 1972, and I don't see any reason to leave it holding all that pressure. It is also much easier on the drive belt to start pulling a zero load as opposed to pulling against high pressure. John

IMHO an accumulator tank is optional. If all you do is fill tires they are pretty much useless. When running air tools they help keep the compressor from running as much but aren't really necessary. I have friends that have both set-ups and both seem equally effective.

I picked up a semi tank. Lots of fitting options on both sides and in the rear. Problem is it is a little almost to large to fit well. I may have to find a spot on the frame where it can fit and not interfear with something.

As far as life expectancy. I can always buy another pressure switch.

Now, I wonder if a heat sink could be mounted to the head or a heat pipe with mini pump to pull the heat away from the unit.

I have a york setup in my 80. It is a york 209 (manufac date early 1970s). The output on the york goes directly to an air drier/oil seperator then into my distribution block. The distribution block has a 150psi safety valve, and 120psi shutoff , a feed to my tank and a blank spot. From the tank i have a hose running into the back of the truck that feed all my air tools and things.

To answer you original question of 150 being safe operating pressure.. its absolutely fine. These compressors were made to be used in r12 systems mostly and the rule of thumb to figure out r12 operating pressures is to take the ambient temperature and add 100. So on a 85 degree day, your AC system would be operating at about 185 psi. As long as you keep the oil level topped off you will not have a problem running this york at the low pressure of 150psi.

That's what I use with my York. It fits perfectly under the floor behind the gas tank on the 79+ Cruisers.

thanks...I woudl like an onboard air setup but may go electric rather than belt drive.

Howdy! I have a York on my Piggy, but no room on my 80 withe the S/C. So, I opted for the Puma NCPD-1006. It is 12v, 1 hp, 1.5 gallon tank, 135 psi, and 100% duty cycle. Fills my 315's from 15 to 35 in just over 2 minutes each. Footprint is about 7" x 12", unless you divorce the tank. John

A little sidebar to the subject: For those that are slim on engine bay space don't overlook the Sanden 508/510 belt driven compressors. I've been running one on my 2UZ-FE/100-Series for the past 1-1/2 years and they're compact and also put out the CFM.

The current version of my OBA system runs the 508 off my serpentine belt and fills my 35" tires from 18 to 52psi in 1:26 (1500rpm engine speed). That's moving right along...

In keeping with Spressomons post here is a whole site devoted to using the Sanden comps. He has some nice tricks to get around the lubrication problem associated with the Sanden.

I have come across that before and it is a great read. Also meaning a factory A/C unit could be used for those that didnt know.

I believe the techniques outlined in the link could be applied to almost any OEM AC compressor if you wanted to trade AC for OBA.

Agreed. Guess I was just more stating the obvious.

i have always run my york at at 150 psi.. i bought a cut out switch from a truck shop that cuts out at 150 and cuts in at 110.. my air tools "sing" and i can fill tires up super quick.. this combined with my 9 gallon air tank under the bed of my truck makes for a great combination.. i run it at 100 percent duty cycle and although it gets hot i have never had a problem with it.. i have the 210 york out of a 1981 volvo wagon.. it sure works great!!

the way i look at it, the york is an a/c compressor that sees high pressures off and on.. on any hot day with a condensor rad that is plugged or partially plugged on a truck or piece of heavy equipment that compressor will see upwards of 160 psi on the high side of the system.. i agree that running this way for super long extended periods of time will shorten the life of your compressor, but it was designed and made to see these pressures...

I really don't see 150 psi as a problem or risk for a York. The reason I run lower is due to belt slap as the pressure gets up around 120. I run a fairly long belt without an idler, which would probably solve the problem. John
