OBA

[rejeep]

I came across a YJ 258 with factory AC.. (Mike already has dibbs on the block)
I have read about the York compressor and finding one from a Benz and finding brakets from a FSJ 258.. but I have a setup already for a YJ 258 with a good working compressor..

So question being..
If I take the 1990 YJ brakets and Compressor.. flop it on my engine, spend the money im saving on a manifold, switches, etc.. what kind of performance can I expect from the stock YJ compressor?  Is it so bad I should spend hundreds on a Kilby?

[MrMindless]

the reason the York piston type is so much more desirable than doing the same with a Sanden rotary type is longevity.  The York has a crankcase full of oil to keep it lubed relatively well even when running air through it.  the Sanden doesn\'t have a reservoir and as such without oil suspended in the gas it\'s compressing will fail much more quickly unless some sort of pre-oiler is used on the intake side.

with that said, if you\'re not running it constantly, you can probably still get a few seasons out if it and the rotary type compressors are pretty much a dime a dozen when it does fail....

One of these would work great for tires and small air tools. Not as extravagant as a york but it will fill your tires.

I looked into them when I was thinking OBA. A lot of people are using them and they are happy.

I did see that, but I also saw a Viair kit for $369..

I guess I really have to see how much hooking up the \"free\" compressor is.. I would still need to buy a tank, fittings, manifold, switches, etc...

I could see this getting up into the Hundreds...  the 12v Viair kit might be the cheaper solution..

I dont think I would have the room for the PUMA system.. it would take up too much room in the back. At least with an OBA setup I could seperate the compnents in different locations to spread the wealth.

[MrMindless]

all those stupid little fittings really add up fast.

i just picked up an ac comp out of a 97 chevy half ton with a working clutch and manifold for 25$.  i will not be spending hundreds.  garbage picked four R410a tanks and have some hose laying around.  i have a 2hp HF air compressor thats very tired and i need a bigger one anyway.  I was thinking of stealing the pressure switch, blowoff, and maybe one of the tanks if the R410a tank doesnt work out (kinda big).

i plan to hack something together to see the performance, with a total cost under 40$.  if its decent ill throw some money at it with an oiler / separator.  

I was talking to Tony (DTP owner) this weekend about them as he has low riders with those air shock things.  he says he loves the newer ones over the yorks because of the noise reduction. The oiler setups arent hard either.

interesting.

i\'ve got about $50 invested on my stock compressor oba setup.i picked up a nonworking 5 gallon pancake compessor for $25 and used the tank and pressure gauge and pressure switch another $25 in fittings hose, wire and switch.paul airs up his 35\'s in about 3-5 minutes

[carchameleon]

yea troy\'s oba works well

[smichaelR22]

do anything for oiling?

[luvmyxj]

in line oiler $15.i do need a air filter maybe i\'ll tie it into my cone intake

[rejeep]

can somebody explain to me the \"duty cycle\" of a 12v pump?
I have been looking at viair kits and im a bit confused.

[MrMindless]

they should describe duty cycle as \"X% in Y minutes\", so in a given period of Y minutes the actual pump can be run X% of that time.  a 100% duty compressor can run constantly forever with no issues.  a 50% duty compressor can run half the time in a given period before it needs to be let cool off.  Often the period isn\'t advertised though.  5 minutes is probably a safe wild guess for a duty cycle period.

[rejeep]

so despite tire fill rates i would want something that would run constant or 100%..
from what your saying the tire fill rate can be manipulated.. (advertising)

[smichaelR22]

a 100% duty compressor can run constantly forever with no issues.

interesting.
