Onboard air
Ok...the concept of onboard air is definetly a good got any ideas on the best way to do it or the most effective way to do the job....(will be for a 460 setup in a bronco,if it makes a difference)

Re: Onboard air
use the stock A/C compressor.

Re: Onboard air
Here are some links. They are not all vehicle specific but they will give you some ideas on what needs to be done and bought. I haven't done this yet but am hoping to do so in the next year. York1 Bronco Air WT Broco Air I haven't yet found anything engine specific for the 460. I do know that Ford used to run York Compressors in some of its older trucks and vans. I'm not sure what years and motors though. You may have to fabricate or have a bracket made to fit your aplication. everything else is pretty much strait forward. Did you do the 460 swap yourself? Do you have Fuel Injection?

Re: Onboard air
there are other ways and better ways(in my opinion) to do an OBA. find a 460 out of a van that had the york style pump, and steal its brackets and pump and bolt it right on. the york style has its own lubrication system, and is the square headed style.

Re: Onboard air
A few problems
a Do you have A/C? Does it work?
b Stock compressors have to have an oil return or the compressor will sieze.

Get a york compressor. Cheap easy and they move a LOT of air. I'm in the procces of putting one in my truck. The compressor was $25 w/ a clutch. I'm making the brackets myself out of angle iron and using the stock serpentine belt. I had to get a new clutch to make it work. I'm putting it in the place of the compressor because i cut the a/c out and threw an idler pulley in there. The york will act as a idler pulley now. It can't be that bad to fab a set of brackets for your truck. A few places sell kit but i've never seen one for a 460. I have no idea how your pulleys are set up. The whole system cost about $150 due the the fact that the new clutch alone cost $90. I have a 5 gallon tank in the bed. If you want some pics or more detail just PM me and i'll tell you whatever you need to know. Good luck.

Re: Onboard air
Stock AC compressor will work if you buy a tool oiler and make sure you keep it full! [img]images/graemlins/blush.gif[/img]. But for the price you can't beat the York. You can find them everywhere on the cheap. It's the rest of the components that make it work that end up doing the biggest dent in your wallet IMO. [img]images/graemlins/cool.gif[/img] NORM

Re: Onboard air
norm, the oil isnt for the tools, its to lubricate the compressor, and i dont think there would be enough pressure to run the oil to the inlet of the round style compresser.

Re: Onboard air
well....its goin to be carbureted for now....until i can either a)find a 460 EFI and molest it of the components that i need or b)fabricate a setup for MultiPort....and yes i will be doing the swap myself....ill keep you posted

**DONOTDELETE** 11-29-2002 06:04 PM

Re: Onboard air
the 460 i got out of a 86F250....radiator to transfer case....ive seen in have 460 mounts to swap right in for either a I-6 or V-8 setups....either way i will be needin a a/c compressor....and if you guys know anywhere i can get CJ heads PM me...

BigNorm 11-29-2002 10:21 PM

Re: Onboard air
That's what I meant Burned. You need a tool oiler on the intake side of the AC pump. Right after the airfilter. I know alot of XJ drivers that use this setup because they really don't have alot of room with that 4.0l up front. It works. Just not as good as a York would.

BurnedBronco 11-30-2002 08:20 AM

Re: Onboard air
ahh, no room in a xj? you lie! we put a 350 in one last weekend!
350 with trans in MJ

Re: Onboard air
IT can be made to work but like you said u need a seperate oiler. For the price of the oiler you could get a York with a clutch. The only thing i still have to do is make a filter for the intake and locate 3x3 angle iron for the brackets. I have a bunch of old brackets from the drivers side of the motor in my garage cause Rep-T and I just both converted to saginaw pumps so i can get the pattern from those but TRY finding 3x3 angle iron. I have a filter in mind for now , fuel filter clamped on the stock york feed line. It'll work for now. I also have a filter inline with the compressor before the pressure switch, check valve, gauge, and saftey valve. The whole system would have cost me about $100 if i didn't buy the clutch for the serp belt. The only problem i had was Grainger doesn't sell to the public and they require 2 forms of bussiness ID top buy their stuff. I had to make up a fake company and go the website and buy the stuff.

Re: Tear a guys head off
YOu need two fomrs of business id to buy from grainger. Never hassled me before but i have been ordering parts through my father who has had a business account with them for 20 years. Thats good to know though. They send me the catalog so its all good.

86convert4wd 12-01-2002 04:32 AM

It's all good as long as they recognize you as a bussiness customer. There's a disclaimer on theier site somewhere that says just because you have the catalog doesn't mean you can buy from us.

Re: Onboard air
Guess im missing something, but what for this set-up did you have to get from graingers?

86convert4wd 12-01-2002 08:09 AM

Re: Onboard air
I got the check valve and the pressure switch. Neither of these are needed unless you are running a tank. I got a 5 gallon tank in the bed of the truck. If you plan on doing an OBA setup plan on running back and forth to a plumbing supply shop or Home Depot about 650 times. I bought a buttload of fittings, nipples, reducer couplings and reducer bushings on the first trip so i only went back a few times. I bought a pressure cut off switch with the unloader valve and the check valve with the unloader valve so the compressor starts easier. If you are only using the system to fill tires and are only using a hose you can get away REAL cheap. I got a filter from Sears on sale for $20 and 2 25' air hoses for $10 each. One runs between the manifold and the tank and on stays in a bag with my impact lug wrench. Once i get the brackets i'll post pics on my superford site(Oh yeah this means i'll have to figure that site out too [img]images/graemlins/confused.gif[/img] [img]images/graemlins/grin.gif[/img]) There were a few good links on the internet. I didn't save any of them though. Sorry
