AC brackets driving me crazy!

[flyboy2610]

And since I'm halfway there normally, it don't take much!
I spent Memorial Day at the U-Pull-It yards in Omaha. I got a PS pump and pulley, the two piece PS bracket with idler pulley, and the AC compressor mount that was behind the PS pump. Also got the fan pulley. It was all a matched set.

The AC idler pulley bracket didn't come off that truck. The PS pump was powered off the third groove of the crank pulley, and didn't go around the fan pulley, hence the idler bracket on the PS bracket. I don't have the pump mounted, but it aligns with the pulleys. The pump that was originally on my truck aligns with groove 3 also. The alternator on the Omaha truck was powered off crank/fan pulley groove 1, if I recall correctly.
I have a 2 groove compressor pulley which will align with both grooves 1 and 2 of the crank and fan pulleys.
It does not, however, align with the AC idler pulley on the bracket, which aligns with groove 3.

It also hits the AC idler pulley bracket.

Since the PS setup came from an AC equipped truck, and I have the PS and compressor brackets that were all on the same truck, and it was all on an FE engine, I am confident those pieces are correct.
My question is: Do I need a different AC idler pulley bracket? The compressor I have hits the AC idler bracket I have now, so I'm wondering if there's a different style bracket i need?
I also have a compressor with a single groove pulley, which fits and aligns perfectly with the idler pulley and bracket. Problem is, that puts the AC on crank groove 3 which is where the PS pump belt is.

Can I run the AC and PS off the same belt? I'd rather not, but I'm running out of options!
I have an aftermarket bracket/idler pulley which I thought would work, but it just doesn't fit right with my PS equipment.


If anybody has any ideas, I would appreciate it. I know it was mentioned that AC equipped trucks had a different PS pulley, but this stuff came off an AC equipped truck and the PS goes on groove three.
Please help me before all my hair is gone!

Here are a couple of pics I have of a factory 72 with PS and A/C, and of one other I have saved on my computer. They both show the PS running behind the A/C pulley with the fan and the A/C out front on the #3 groove... You might also check with Zakt he has a complete FE motor with A/C and PS that he had pictures of how the pulleys were on his.

HTH...

here is my truck before i did any work to it it doesnt have power steering when i got it thou but it has both the two grove a/c as well as a two grove alt, back two that are on the crank are alt. Front one is for a/c and the one between them is for power steering.

Thanks for the replies!
I understand what you guys are saying, but given that the PS pump, PS brackets with idler pulley, and compressor bracket all came from the same truck, and that the PS idler pulley lines up with the third groove, I'm sure that's where it should go.
I have the original PS bracket without pulley I could use if I could find the AC PS pump pulley.
Given the above, though, I have feeling there's different AC idler bracket that would locate the AC on groove two.
I'm totally confused.
Maybe somebody has something for sale.

You have the wrong power steering pump pulley for an AC truck. The picture you show is the deep one for non-AC, the AC one is pretty close to flat. The 4th groove you have on your crank is an aftermarket AC pulley and Fords do not use them originally. The problem is you are mixing and matching AC and non-AC and aftermarket AC stuff. Simply take off the front pulley from the crank, use a single groove alternator pulley (or just leave the front groove empty) and get the right PS pump pulley and then what you have will all go together just fine. The PS brackets have the same offset for AC and non AC but the one for AC has the idler pulley for the AC belt (what you have shown). The PS pulley you need is actually quite common on late 60's Ford cars. BigEd

Thanks! I posted an ad in the Parts Wanted section for the pulley.

[SteveC]

i ran into that problem with the ps not lining up and had to make spacers on a lay to get every thing to line up

[flyboy2610]

I't just kind of strange that the pump I got off the donor tuck, along with the PS and compressor bracket, lined up with the third groove. Maybe someone swapped out the pump at some point.
Naahhhh! THAT could never happen, could it?

[rjewkes]

it could have happened. also worse demons out there than ac and ps on the same belt, heck for example the gm serpentine belt. I say gm cuase caddy was the first i ever saw use them.

OK, I did some searching and I THINK this part number will work for a PS pulley for an AC equipped engine: ( 6AA ) C7AZ-3A733-E.
Here is a pic of one:


Is this the one I need?

Another Part number I found is: C7AZ-3A733-A
One vendor has this description, but no photo:
Part Number: C7AZ-3A733-A
Category: Steering-Power Steering Pump
P/S Pulley 5-1/4"; 65-67 V8 with A/C
Found a pic of one:


If someone good with part numbers could check on these for me, it would be immensely appreciated!

I thought your A/C was finished, what, a year or so ago? Did you get a new truck or something? I've been out of the loop for a while, I don't know what's going on anymore.

[SteveC]

i may have one of those... ill look tommorrow and post back on here... i have a extra pully from my p/s swamp ill check the numbers on it

[flyboy2610]

Thanks, Steve!

[SteveC]

ok what i got isnt the same part number but maybe it cross refrences
(6B) D0AR-B S

that is all the numbers on it

[BigEd]

6AA is what you have (or it is an AG which is identical). Anything that starts with D won't work, it is for a 70's smallblock or 385 series, not for a 360/390. 7AA, 7AB, 7AE, 7AF, AA, AB, AE, AF etc... is what you are looking for. BigEd
