Do you already have a compressor in your Jeep? If so will it be for the OBA? If not you'll need to add an A/C compressor. Thinking Sanden or York? When I did mine I bought the Coalescing filter, intake filter, pressure switch, check valve and pressure relief valve from Kilby. The inline tool oiler was mail order from Home Depot and the rest of the basic plumbing fitting were from HD too. The Sanden compressor was out of an XJ. If you are using a Sanden you should add the inline oiler on the intake and the coalescing filter on the output to extract the oil. Otherwise you'll be spewing oil into your tires. The Kilby order hurt a bit but I'm glad I went that route. It's worked flawlessly for several years now.  |

i do have the stock AC compressor, and I'd like to keep the AC so I was planning on going with this bracket: www.kilbyenterprises.com/KE-2000.htm I was assuming York because of the self-oiling but maybe a Sanden with a re-circulating oil system with the coalescing filter is the way to go. I presume Sanden compressors are cheap and easy to come by? I wonder if a Sanden will work with the bracket. Do I need the coalescing filter if I went the York route? i'll need a new pressure switch and safety valve but i think everything else is ok. I was planning on plumbing my intake box for clean air. i'd like to do this once right and never touch it again! |

The picture of the bracket looks like it will mount either style pump.
The Sanden pumps are all over the place in salvage yards.
I went the low buck approach and didn't bother with a pre-oiler. I just run a cheap inline water filter before the check valve and squirt some Duralube into the fill plug on the pump a couple times a year. My air inlet filter is an aftermarket valve cover breather.
The last time I had to replace the pump was back in '05 when the clutch burnt out.

I'm in the process of gathering parts for my system too, and just about everyone I've asked used the Kilby filter. I've been able to find similar ones cheaper online, but usually they aren't up to spec on paper. (won't handle the heat, made with plastic bowl, etc) I'm not an expert, so I don't know if any of that stuff matters, but I would rather do it once than have the thing break on me. As far as the bracket goes, I found a used Kilby one on ebay which helped save a few bucks. I will say the bracket is really well made- reminds me of the Rokmen stuff. I was able to find a used york on Jeepforum locally, but I have seen them in local boneyards and they're not that expensive. I've seen them with the right clutch in early 80s mustangs. If you haven't seen this guy's writeup yet- there's a ton of info here on his system as well as links to identify and test a York before you pull it from the donor car. www.jedi.com/obiwan/jeep/yorkair.htmlHope this helps!

great info guys, thanks! The cheapest route may be the kilby bracket with a junkyard sanden. john, do you have a sanden or york? could i periodically add some oil to the inlet on a sanden and get away with it? how do the clutches work? do i need a new one? would a junkyard clutch work?

I'm running a factory jeep sanden style pump.
The clutch is electrically engaged. There's a wire that comes off the front area of the pump, supply 12v to it and the clutch engages to drive the pump. With the 12v off, the clutch disengages and it just acts like a big idler pulley. New clutches are $$$$$ If it goes, you're cheaper off heading to the junk yard and getting another pump assembly. (a quick search on my local yard's site $35-$50 depending on model year for an XJ)
Mine's wired up with a power switch to the pressure cut off switch which then goes to a relay to control power to the pump's clutch.
My pressure switch is the lowest cost adjustable air compressor switch the local air compressor supply shop had on the shelf.
The nice thing about the Sanden pumps is the shape. They look like a log and tend to fit well under the hood.

cool, so it looks like i should go find a junkyard sanden with clutch. i'll call kilby to check about the bracket. anything else i'm missing? anyone know a good junkyard or junkyard search engine to find the sanden and/or a cherokee with a/c? honestly i've never pulled something before (just walked in and purchased) and i'm not sure the best places to check.

Jack's in Billerica isn't bad, but I haven't been to the other one. I have also been to Wilson's Auto parts in Pepperell, Anchor Used auto parts in Pelham, NH (I think). There is one down in the Boston area Andy L has delt with a few times. For an AC compressor you probably won't have to pull it yourself, but you may be able to. JW |

Hmmm... That bracket is interesting. I wonder if there is a way to do something like that on an XJ engine. Unfortunately in my engine compartment the AC compressor is located where they show the alternator and vice-versa. JW |

I bet with a little careful measuring you could weld some bits on to connect a Sanden with that bracket and it would still work. The Sanded has bolts that connect it which run parallel to the compressor body... Add some tabs to Kilby's plate with holes in the right places and it should work. JW |

JW I mounted a Sanded to my bracket. It just required a couple of pieces of 1" angle iron cut and drilled. Works great!   |
