York setup on a 4.2 (V-Belt)

[jfogarty]

I've been gathering parts for my OBA system, specifically the brackets (and the York) off of an AMC Pacer. I went to install the compressor bracket and the alternator re-location bracket today, just for a trial fit. It seems that the alternator is too far forward (almost touching the fan) and the York is too far back.

Has anyone done an OBA setup on a 4.2L with the factory brackets? Does the alternator go in front or behind the left-most hole (as you're looking from the front of the Jeep) on the compressor mounting bracket? It doesn't seem to want to fit behind. Which of the two sets of four mounting holes does the York go into?

The orignal setup on the Pacer was not very helpful, due to the fact that it was a triple V-belt configuration (triple pulley on the crank) and I am hoping to keep the standard two belts, with a short one running between the compressor and the alternator.

Any help or advice would be greatly appreciated.

Hey man I have the spacer for the fan I think.

I'll sell it to ya for 10 bucks or so...I don't need it.

It came with the Kilby kit.
You'll just need longer bolts.

Thats probably what you need.I also have a good diagram if I can find it,I'm gonna scan it and put it on my site, I'll post it here if I can.
Incidentally my york pulley is 1 or 1.5 inches away from the fan.
No probs so far.

If you are around tomorrow I will be going up to Charlys.

We're going to Hiway to get my 44 front.


I'll bring the spacers and anything else I have, and we can check
it out if you are there.


EDIT:: OH now I get it you arent running the 3 belt set up...the only way I can figure you could do it with two really is to have a double pulley on the Alternator.
One from belt from the alt to the crank, and one from the alt to the york.
I'm running the three...the kilby kit gives you an add on one.

I got my stuff off of an AMC. First - it sounds like you have the double pulley on the York, which is what you need.
The inner belt on the York is smaller than the outer & goes to the alternator.
The outer belt goes down across an idler mounted on the alt. bracket to the outside (forward) crankshaft pulley, then up to an idler pulley mounted on the driver side of the valve cover & back to the York.
My York is mounted upright on the set of holes closer to the engine & the alt. bracket only allows 1 mounting location, having a cradle type lower mount that the pivot mount on the alt. sits in.
Maybe you got the wrong bracket because it's for a triple crank pulley? If you can't make it work, you probably need to look for an AMC w/ a double crank pulley like your Jeep. I know I saw different configurations when I was looking. There are still quit a few old AMC's in the Pick-Yer-Part type yards around here, they might be more rare in your area.
Hope this helps.
Oh Yeah, don't forget to check in, Newbie

I generally get laughed at when I ask about AMC anything around here.
Long gone most of the stuff.

We are in the rust belt after all.

We all dream of the vast piles of AMC's and D60's, and flawless Jeep tubs dating back to WWII that you all seem to have access to in the west and Southwest.

Someday I will follow the yellow brick road to OZ.
