If I got a York compressor do I need a tank? I would not be running air tools often if at all. I would mostly like it to air up my tires.

Dose anybody having a wiring diagram or instructions to wire it up so I have a switch to engage the clutch?

Also could I just run a line (after an oil filter) to my tires or would I need something in between.

Thanks for your help

Air tank is not needed since you'll empty it in no time at all.
They work well with air tools if you keep the rpm's up and using a hand throttle will help with that.
Stu Olsen has a good write up and there are tons of other write ups all over the net. Get the correct bracket or build your own since there are differences depending on what year TJ you have.
There are a a variety of options you can use for filtering the air and oil. I have nearly everything to hook up my OBA, but I just need time and a free weekend.

Good luck in your search.

Thanks for the help. I'll look at Stu's write up.

Do you know where I could get a bracket or some ideas on places to mount it?

If you were closer I would say I would come help you install yours for some pointers.

To my knowledge no one makes brackets any more kilby did but they went out of business I was lucky and found a York with all the brackets I just had to fab up a way to run the belt which I figured out. I ran a tank for mine and I mainly use it to air up tires. Reason being that the compressor won't keep up filling my 35s so I have the tank to keep up.

I was looking online and saw ORO made a bracket but it's expensive.

Dose anybody have specs to fab one myself.

I can write more on the subject tonight but yes, a 2. 5 gallon air tank is highly desirable with a York when running air tools. An air tank helps with refilling tires faster too. I ran a York on board air system in my previous TJ for years.

That covers 2000-2006 not prior years

If you don't mind could you. Thanks in advance. I'm not that concerned about speed. If I don't get a tank now could I add one later?

My buddies jk has a warn winch with a built in air compressor I don't know how those r compared to a York or anything but filled my 31s up preety fast

I just looked at that since I don't have a winch but those are more expensive than a OBA kit w/ York from kilby

I love Warn winches but their Powerplant, the one with the built-in air compressor, is just plain huge. Too big to look right on a Wrangler TJ in my personal opinion.

But even if it wasn't so huge, I wouldn't want two critical tools like the winch and air compressor combined into one fail-point. I trust Warn but I'd rather have a separate winch and compressor. Not to mention the Powerplant is finicky in that there can't be any residual air pressure in the system when you want to use the winch... there is a pressure switch that prevents the winch from operating. So if you had the compressor hooked up to anything like a quick disconnect, air tank, long hose with a quick disco or filler accessory at the end, you'd have to let out all the air pressure before the winch will work.

On the air tank, it is very useful when using high air volume consuming tools like grinders or sanders. The compressor cycles on-off to keep the tank filled which serves as a buffer between the tool and the compressor. And for refilling tires, the tank provides a nice initial rush of a huge volume of air into the tire you're refilling which speeds the refill process.

I installed my 2.5 gallon tank underneath between the frame rails, near the driveshaft where in 8-10 years never took a hit on the rocky trails I love.

You want to go with the largest capacity York compressor which is the F-210, which indicates it has 10 cubic inches of capacity. With the engine revved up a little, that York can put out over 10 CFM and 6-8 CFM just off idle RPMs... and that is into 20 psi of tire pressure. My big upright belt-driven shop compressor can't put out that much air volume.

Most 12 volt compressors you see used on the trail are lucky to put out 2 CFM and some of those use the very misleading spec of saying their CFM is into 0 psi which is a useless rating. Heck our lungs can put out probably 15-20 CFM into 0 psi (open air) but put a little resistance there and that amount would drop off to near nothing.

Thanks for the info on which compressor to look for

So if I were to only use an impact driver I wouldn't need a tank. I was trying to avoid a tank to reduce cost but still have a good compressor that can fill tires relatively quickly

You definitely would not need a tank with the York just to run an impact wrench. The York F210 compressor can easily keep up with a typical impact wrench's lower CFM requirements.

So without installing a tank what would I need on the output end of the compressor

The air coming out of a big high volume compressor like that is HOT, hot enough to melt standard air hose and anything plastic. Some people connect a coil of copper air line to the output so the air can cool enough and then a fitting for a hose and quick disconnect. Or you can use something like a high-temp Goodyear hose right off the compressor and attach a quick disconnect at the other end.

Be sure to use 3/8" inside diameter fittings and hose, 1/4" size hose & fittings would significantly reduce the CFM output ability of the OBA system.

Ok so if I would put a T in and run a line to the passenger side and driver side door area and then put a quick disconnect there would that be a far enough run to dissipate the heat. Also would putting a T in affect the CFM.

So long as the T had a 3/8" inside-diameter it'd be fine. You just have to insure whatever you attach directly to the air compressor can withstand very high heat. My high-temp Goodyear hose had no problem with it. It had a kind of reddish color like you can see below of my York OBA system.

Would filling tires with the hot air make a difference in the PSI in the tire

Would putting in a manifold do anything or is that for a tank

By the time the air would get to the tires though a typically long length of hose, it'd be cool enough to be a non-factor.

I added a photo of the Goodyear hose I used to my above post.

I was reading online and a lot of people put in regulators and manifolds is this needed if I don't put a tank in

Where can I get Goodyear hose

A York is an expensive way to air up tires.

I never felt the need for a manifold or a regulator. What you do need to add is a pressure switch to shut the compressor off whenever the air pressure in the line reaches somewhere around 120 psi. Since air pressure switches often have a high amount of plastic content, you want to mount it well away from the compressor to avoid it failing from heat. Pressure switches also act like a regulator in that they turn the compressor on when the pressure drops to around 80 psi and off once it reaches 120 psi... exact on/off pressures of course depending on the switch you select.

The air pressure switch is wired in series with the York's power wire that provides 12v to the compressor's clutch solenoid.

It is CRUCIAL that any OBA system have a pressure switch to insure the air pressure never reaches a level high enough to start blowing components out. A pressure pop-off valve is recommended too, that type of mechanical safety valve serves as a backup to the air pressure switch.

So wire batt>switch>pressure switch>clutch. Or do I need a relay.

Where can I get a pressure switch?

Yep that will work fine, connect the on-off and pressure switches in series with each other. No relay is needed.

Sweet. Thanks jerry for all the help

Now the big question where can I get the all the parts
pressure switch and the relief valve that are set to 120 PSI
Mounting plate Goodyear hose
Fittings I can get at Lowes/Home Depot

Any thoughts

This style air pressure switch works well... http://m.summitracing.com/parts/air-24544

That one has a little lower upper pressure limit which would work fine in an OBA system.

I sourced a lot of my parts for my oba on ebay found a 2.5 gallon tank for 65 the biggest expense I had was my filter which a lot ofpeople don't run but I opted to just for peace of mind to catch any residue oil coming out of the compressor. And idk how jerry ran a pressure switch and a pop off valve without a manifold but I had to have one to run those items. It's what they screw into. Anyway all in all this was a very worthwhile mod in my opinion. I had right around 400 in mine after it was all said and done and that's for the York the brackets all the hoses, manifold, all the switches, wires, quick connects which i have 3 one under hood one at the front bumper and one in the rear of the tub in the corner, the tank and all the fittings to hook everything up. But one of the biggest expenses for my system was the filter which cost me 120 for the high temp high pressure style coalesing filter that the kilby system used.
