    So far I've made a tank out of one of my rock sliders, and now I need the pump. I figure I can run it off the 283 from a York air compressor. AFAIK, some used the freon to lubricate the pump, some didn't. How can I tell which compressor is which?

    Sammy, York compressors have their own sump for oil which is why they work so well as an air compressor. They will throw oil out into the air line so you will need a separator in line and need to check the oil level periodically.
    Some compressors did use oil in with the freon as it circulated through the system, but it wasn't the freon itself that did the lubing, it was the oil with it. On those types of compressors an in line oiler like used on air tools works ok.
    The York compressor should have this done so it doesn't blow out oil.

    nick is right I think , all Yorks were made to throw oil into the system. you can follow the Kilby site for most info , how you can tell which pump you have is to pull the clutch and see the shaft chamfor(sp?) the one in the picture is a 210. I THINK the 210 model is the best one of CFM and bore size. , mine was the good one . I was plauged with oil problems so,,,, pulled the pump head and ran a screw into the oil feed line and that stopped only some but not nearly enough.it was a mess!!! so then I got the same EXACT filter as Kilby sells for $115 for $44(Intersate Pheumatic W1060A-047 at my local hardware store .these are for high pressure stuff. this filter was worth the $$ .HF stuff I feel would blow up . Grangier supplied the check valve (3/8" 5X781 $17) and alot of push on style hose barbs more expensive- but I feel worth it , you don't need clamps. ORW scored me a Viar 1 gal tank ($46 the Viar 5 piece tank fittings $10),,I also bought about 20 feet of high pressure Parker hose . I run the system with 1 click of the hand throttle and it pushes that gauge up fast , it's impressive.... and will supply at least 50 psi constant. my switch is a 140 on to 175 off with a blow off of 200 psi.
    the system will still blow oil but the filter will catch most of it , the filter has a site tube and you can see when it's filling up ,I then ran the return line out of the special filter and when running you turn the ball valve SLOWLY! and it will force the oil back into the pump , there is about a Coors beer can full of oil in the pump. I can get pics of my set-up or answer any other info .this weekend I pumped up about 20 tires from trail pressure 5/10 to 30 psi . no problemo...........

    yes Steve I'd be very interested in detailed pics as well

    Sammy I'm planning on using the A/C pump that came on my Ford 5.0....the plan is to plumb a oil reserve that can oil the pump as it pulls air into the system..........and a filter that cleans the air on the way to the tank. I'm using a old 5lb acetylene bottle as a reserve air tank.......much of the parts have been scavenged from old compressors
    here's a few helpful links.....think I have others

    I'll have to look but one of my old A/C text books had the specs to build the dipsticks needed for the York. There were different ones depending on how it was mounted. I'll have to dig around and see if I still do.

    no need for a custom dipstick really , if it's a side mount measure oil 1 beer can full dump in and mark a gutter spike and put it in the trail tool box, or you could buy the one Kilby offers,,,,,,think the level is around 1/2 to 3/4 "

    The dipstick was just basically a piece of welding rod but it had the specs for the right height for the different pumps. It showed right where to mark the rod for the application being checked. IIRC it showed where to make marks for high and low levels.

    I modified a Saden compressor that came stock with my buddy's jeep we just drilled and tapped the fill plug 1/4-28 for a zerk fitting pumped it up with some lithium grease and walla no oil and it pushes as well as a York and is a allot smaller.
    The pump has been running know for about three years and has been on some fairly harsh trail rides and has had no problems.
    I had a bunch of Yorks around but we could not fit the under the hood with the modified set up we put in the jeep so we figured what the heck we have the compressor laying around if it blows up we will figure out how to install a York when that time comes.

    the sanden is another way to go , just the pistion is a little smaller but still a good unit.you need to drill for the zerk grease fitting for it to live.

    The Yorks use a crank dipper for oiling, just like the old 216 Chevy's. The biggest problem will be building the bracket to fit it under that low hood and keeping it clear of the fenders. This is one place having some latter heads with the accessory holes in them would be a real benefit. As to the dipstick, my 74 FSM has a diagram for making one (and also instructions for rebuilding the compressor).

    I bought my air cleaner, unloader/check valve, line filter, SD pressure switch and just about everything else from Grainger. I am using a sintered breather in one side and the oil return line from the line filter is plumbed to the other. To empty the oil back to the compressor, you just turn the valve on the bottom of the line filter-done after bleeding the pressure down to less than 5 psi. I run my system at 150 psi.

    so the grease doesn't get pushed out the discharge line?......sounds like a great solution to one of the issues I've been wracking my mind over :tea:

    copied from my local group

    Hey Rob here are some pic’s and a parts list from when I did my on board air install on my TJ.

    I sourced the compressor from an early 80’s Volvo sedan in the Santa Paula junkyard for 20 bucks. They can be found in old Ford’s, Amc’s, and others. You want to look for the Vin tag on the front of the compressor. Look for 210 R. They have a manufacture date or rebuild date on them too. Mine was redone in 2001 and I got it in the junkyard in 2003. Most have dates from when the car was manufactured-70’s to 80’s.

    The majority of the other parts were purchased from Kilby Enterprises now onboardair.com then for a cost of about 400 bucks. I would recommend buying the parts in red from Kilby for ease and quality of product. You might be able to save on the clutch I think Chris S. got his for 60 something bucks and I paid a 100 from Kilby. My tank is a 2.5 gallon with six fittings. It is mounted on the drivers side under the rear passenger foot well next to the transfer case. I mounted a pressure adjuster and ARB switch on the tank. My ARB wanted no more than 90 psi. The rest of the system runs at 160 to 170 psi.

    At a minimum you will need the following to compete the install:

    -Serpentine clutch 6 groove
    -Mounting bracket(mine was for AC –to keep existing ac and add the York)
    -Flange fittings for the top of the compressor(you may be able to use the one that come
    with the comp. but for 25 buck these ones go right on easy)
    -Intake filter
    -Air gauge
    -Tank 1 or 2 gallon (mine is a 2.5)
    -Safety blow off valve(adjustable is best)
    -Pressure switch (adjustable is best, to cycle clutch)
    -One way valve(to stop leak down of air when compressor is off)

    Other parts required will be to set up your system in you rig how you want it. Some sort of manifold to mount the switch, gauge, blow off valve, front/rear lines, pressure regulators for ARB’s ect… A whole assortment of brass fittings, tees, in’s out’s, ect’s. Air hose too 

    Here is a pic of the engine bay.

    Here is a pic of the intake filter.
    [​IMG]

    Here is the Flange fittings on the top of the compressor.
    [​IMG]

    Here is the mount. It moves the alternator down and adds an extra pulley.
    [​IMG]

    This is my home made manifold. It has my gauge, blow off valve, pressure
    switch, line in with one way valve and the line out to the tank.

    If you're going to run serpentine, there's a vendor on ebay now who's selling the york serpentine clutches at a good price...
    here's another place selling them at a good price. I got mine from the ebay seller. Otherwise, you'll run across v-belt clutches easily.

    I just finished making a bracket on mine. I ended up cutting the existing bracketry on the motor and fastening the new bracket onto that. I had several things get in the way that made it a challenge to mount (dipstick tube, sensor, air cleaner, coolant reservoir, radiator/grill support, etc)

    electric what?.....the small electric are slow.....even the high end units are not 100% duty rated so they need to cool down between uses......and the volume is not up to par with motor driven compressors...IMHO

    We get a very very small amount of oily residue in the trap sometimes after a long day of wheeling.But I am not sure if this just residual oil in the compressor or the grease separates after awhile.

    And this compressor is constantly running one because there is a slight leak :D:rofl: and we are running an air locker on my buddy's jeep as well.

    And we are always the designated tire guys at the end of the day when everyone is ready to head home.

    We also have a five gallon air tank onboard and it takes the compressor less than a minute at idle to pump it up to 130psi.

    The older twin cylinder compressors work really well, you can run air tools with one without a tank.
