Hey Guys

I'm collecting stuff for my latest mod and wondered if any of you might have some feedback on the subject of onboard air.

I went to my local Pick-u-pull and found a York mo# ER210L, That means 10.7 cid (the biggest) two cyldr Rotolock (Flange styles the best usually)
Just make sure you get the hoses and you're ok there.
I chose the York over Sanden because of it's crankcase setup, don'd need to install an oiler just a return line from the coelesing filter to the crancase.
The Sanden you'll need and oiler and a coelesing filter and have to empty and fill the fluids every 6 to 14 times you use it, APROX.

Here's the problem.. Finally...

I haven't been able to find a mount that keeps the alternator up high and use the York at the same time.
The mounts I've seen  either mount the alternator under the compressor, way low (can you say wet alternator) or the add a homemade pully that bends the v-belt way too much causing early failure.

Brad Kilby has some great brackets but apparently doesn't care much for our four bangers (or at least ones like my 1989) because he doesn't offer one.
Look forward to any input, Thanks, Brad :?

You'll probably have to make your own.  I don't see the alternator mounted lower being a problem.  The later 4.0L's had the alternator mounted lower, I believe.  I haven't looked at any pre-91's to see what would work though.

I have run two of Kilby's mounts on my Jeep.  The reason why he doesn't bother making a mount is because it's not cost effective.  He doesn't even make mounts for the 4.2L.  They usually get mounts off AMC cars with the same engine.  The later 2.5L's share the same mounts as the 4.0L's so they are plentiful.  Not to mention they continued to use the same setup till the end of the 2.5L.

Looks like he's got a 4.2L.  I'm not sure if I'd call it good since there are no pictures or diagrams of his mount or close up's of the compressor.  He could have easily found a bracket from a AMC like I mentioned and used a York.

:?  Not sure what all that means in York post, So!  I was told that I could simply find an AC compressor from 4cyc and bolt up and maybe add ~2 gal tank for onboard air. any ideas on best fit and easy install?

Well, it's somewhat easier but there are still a lot of things that need to be plumbed and fitted.  Since the non-a/c bracket is only $35 it would be better to go with a york.  As the Brad once stated, you'll need to plumb a filter/seperator and an oiler to a sanden to keep it oiled properly.  The YOrk has it's own crank case with a seperate oil res.  Although you will get some oil in the lines still but you can use a seperator for that too.

YOu probably won't wnat a A/C unit from any small car.  Some are too small to use.  Most are Rotary style which means you'll need an oiler system unless you want to burn it out.  It would need to be from a Jeep.  Perferable a 2.5L or a 4.0L since they use the same compressor.  Although like I mentioned above, you'd be better off with a York.  If you have A/C already you'll need a bracket that will move the York to a new position and Kilby is the only place that sells those.

Keep in mind this won't be a cheap project.  You'll probably be looking at $50-75 for the compressor.  Then anywhere from $50-100 for all the small parts. ANd you'll still need to buy a tank.  Then you've got to figure out how to mount it in the Jeep and route it.  Don't forget about switches, pressure gauges, cut off switches, popoff valves, hoses, etc...  There is a lot of small things that can nickle and dime you.
