Has anybody converted the A.C. pump to onboard air pump?
Is it worth it, or should I just spring for the York kit?
Don't need alot of full time air, just air up at the end of the day.
-
Guy in my club has been using the stock sanden for years, just need to remember to toss some oil in once a year and it seems to work fine.
-
I've had a York on my Jeep for years. BTW, a York is an A/C Pump. It's fast and if you have 35's or even 33's, it will fill them up fast. Find a York in a JY and buy the Kilby bracket for $35. You can find everything else at the hardware store. Keep in mind you'll still be spending $50-100 on a tank, and all of the small bits, but it's worth it.
-
I know the York is the better pump, but the stock A.C pump
is smaller, will bolt to the stock bracket, and I can use a stock belt.
The down side is they are not self lubricating like a York.
I was just wondering if the A.C. pump put out enough C.F.M.
-
Yorks put out 6,8 or 10 cfm depending on which one you get. A sanden puts out 8 or 9 cfm depending on which one you have.

If you have neither then it won't really matter, The only different is it costs $35 for the bracket on the York, but you'll need to run an in-line oiler and separator on the Sanden since it doesn't have an oil slump. The York will run a 6 groove serpentine belt and unless you already have A/C, you'll still need to buy a new belt. ($20)

Thanks for the info,
I realize I would have to buy a new "A.C." fan belt with the stock pump,
and just taking a quick glance at the Mc Master Carr catalog,
the oiler and seperator look a little pricey.
More than the extra money a York would cost.
Any ideas of where to buy these cheaper?
-
York's you should be able to find at the Junkyard, its a tough compressor and was widely used on domestic cars and trucks as well as big rigs. These days the sanden compressor is pretty much displacing them
-
You can get an oiler and filter for about $12. McMaster is the wrong place to look for pretty much anything if you want a good price.
Something like this would work fine.

What filters are people using on there York oba?
-
I think they are using just an air filter on the intake side,
and maybe a water seperator after the pump.
The sanden needs oil going in and a filter to take it out
after the pump.
-
I run an actual compressor filter. It keeps the noise level down as well as keeps water out.

None. The air tank is my "filter". I put the tank with a drain cock at the lowest point so that all of the junk could collect at the bottom of the tank. It is simple and cheap. It is the same way the railroads used to do it. If you are interested, I can get pics of my setup for you...

I believe he means on the intake side of the compressor.

That sounds interesting I would like to see that setup. The tank I got only has one port yea I know it's not as efficient but it still gets the job done. I know that there is oil in the tank so that drain cock sounds like it will work for my setup.
As for the filter I was talking about for catching the oil that comes out of the York the one that is linked to the ebay add is similar to the ones I have seen at harbor freight.

You don't need to take oil out of the air for the York compresser.
It has a contained oil system within the unit.
The Sanden does not and has to be externally oiled by the incoming air.

Well, yes and no.
The York has a oil slump where the oil usually is. BUT if you take the top off the compressor, you'll see that the slump is open at the top and can get into the air flow. This can be a problem when mounting the compressor on it's side. If you do this you need to make sure the compressor is laying with the intake side up. Otherwise, you'll get a lot of oil in the lines. Still, you'll get some oil in the air if you don't use a separator.

Jeffy is right
Another way to stop oil from getting into your airlines is the vent the crankcase. My york is mounted upright, and i was still getting oil in the lines so I but on a coalescing (sp) filter and that cleaned up the air but the filter has getting filled up more than I liked because if you run a york without enough oil it will burn up. So, i heard about venting the crankcase. I thought i would try it. I replaced one of the fill plugs with a bronze filter and now i get no oil coming out of the compressor. so if you want the easy fix just vent the crankcase, it was about $9 in parts and 5 min to install :beers:
-
I did this mod to the York to minimize oil pushed into the system: http://members.cox.net/cglabe1/Air/OilFix.html
-
I havea AC pump from a XJ on my YJ and I have enough air pressure to run air tools. I know there is enough preaaure to fill tire. I put a tool oiler on the intake and a coalescing filter on the output it works very well.
-
Just found this and thought it might be helpfull to others aswell and when I do this mod to my york I know where to find it too! It's for plugging the oiling hole thing with out having to take the York off the engine and all the other hassel of tap and die.
Very easy mod will help stop about 90% of the oil blow by.

nic99007, where'd you get the bronze filter to vent the crankcase?
-
it's a "muffler" from grainger. part number 1A327 on thier website. found it at a local industrial supply parts house.
-
here's a pic

-
I've seen those. They have the adapters too? I think I'd try it at a 90º upward if possible.
-
yeah they did, once i found the right filter i just took the drain plug out from the side that I wanted to put the filter in and took that into the parts house and we rigged up the adapters to get from the treads on the York to the NPT threads on the filter. :biggrin: it really works great. i have not had any oil in my coalesing (sp) filter since.
-
If you put the screw in the york to help stop the the blow by is that vent needed? And for those who don't have grainger acount how do where could one find that part at?
-
I plugged the hole behind the bearing cover and I still get a lot of oil in my filter, going to try that crankcase vent next.

i've heard that plugging that port works only so-so. and that it could starve parts of the compressor for oil. so i tried the vent and it works very good. but i never plugged that port so i can't compare the 2 methods from first hand experience. Grainger is a wholesale only operation. So, I told them i was a car lot and needed a few small parts occasionally. :naughty:

I run the sanden factory compressor for my OBA system... But I run grease in the unit instead of oil.... Check out this link for more info...

Ive been running my for years now with out any problem and no oil in the system....
