A/C and On Board Air

Stukboy · Jul 23, 2010

So, I have a 92 4.0 XJ with air. I want to put the big York OBA set up from my YJ on the engine.
Any have or hear of anyone running both?

When I pulled it from the YJ it was a 2.5 4cyl. So I can't just bolt it up.

Any help would be appreciated.
The wife wants air in the summer. I don't really care but want to keep her happy.
Thanx,
Stukboy

Look into Kilby Enterprises, they make some bracket kits for 4.0's

It's been done successfully. Here's an old post from way back when, but unfortunately some of the pics are gone. But the remaining ones will give you a good view on how it's done....

That thread is about using a second Sanden compressor for OBA.

Yes, you can install the York and keep your AC. As xj9140 said, Kilby does have a bracket and pulley kit for 91+ XJs. It's part no. KE-1700, which is not listed on their website. You will have to make some minor mods such as relocating your airbox and battery.

I first installed the York OBA system in my 98 XJ. It's now been swapped over to my 92 MJ. My favorite mod.

Thanx, I did a search for OBA and came up with junk.
Pics are good if anyone else has them.

Interesting. I wonder why Kilby never put the KE-1700 kit on his 98 XJ.

You can have both. My battery is in the back of the jeep. I used piece of an I beam cut in half and turned on it side for my mount.

Try lookin on Madxj there a couple on there!

I have done it, only with a second Sanden compressor due to lack of space for the York

Here's mine.

OK, thanx everyone.
What i'm looking at now is how you are running a V belt and a serpentine(sp) belt.
I like the side by side on all the set ups.

The Kilby KE-1700 kit consists of the brackets and a new alternator pulley, which has a groove for the v-belt to drive the York.

If the York were to suddenly seize up, I can take the v-belt off and keep on driving.

OverlandZJ · Jul 25, 2010

What was the cost on the Kilby bracket/pulley?

johnnyc · Jul 25, 2010

I think it was like $130 when I got it several years ago. Looks like it may be closer to $150 now,

What's the hot ticket for York compressors? I think I read that there's three versions (vary by cc), and how can you tell them apart? I found a beauty the other day, and will snag if it's the right one.

Model 210 is the one you want.
