Help!
Friend mentioned article in Mopar Action "Pump it Down" October issue. I can't find it on the stand.
Does anyone have this article?
I have my power steering pump out right now and going to put back in this weekend thought the modification would be good. Basically it decreases the pressure on the valve by shimming the high pressure port fitting.
My friend does not remember the details.

Thanks for anyone's help

Mark

I sure would like to read some posts from people who have done this! Been thinking about it, just haven't gotten around to trying it. As I recall E-booger recommends a .031" thick washer/shim for the task.
Anyone done it???

I was flipping thru some of my old issues of Street Rodder about a month or so ago and came across on article where they installed a valve inline to regulate the pressure. I'd have to find the issue again to tell you who made it.

Seemed like an easier (though not cheaper) solution.

I'd like to know how they do it. Power steering in these older mopars isa bit over powered.

I'd be interested in this too as my pump is out at the moment.

What is it, some kind of washer to restrict the flow?

No its just a washer (of a certain thickness, again I think about .031) to compress the valve/spring assembly in the high pressure line a little more than stock. Simple simple simple.
I just have never tried it or heard from those who have...

well guys, i had a "super meltdown" on this stoopid pooter last friday/saturday and lost everything. i just got back online as of this morning, and i think my scanner is fried. the basic idea of this article is that a "shim" is inserted into the spool valve on the pressure side [outlet] that lowers the output pressure from approximately 1400# to somewhere around 750-825#. this makes a very noticeable difference ! i like it a lot ! but the hard part is getting the correct washers to use as shims. e-booger recommends adding approximately .062[1/16th"] to whatever shim[s] you may currently have in your stock valve. the shim washers are 1/2"od.x 3/8" id. one way is to drill out a 1/2" od. washer to 3/8", which is almost impossible to hold. what i did was to stack some 3/8" id copper washers on a bolt and turn 'em down on the lathe. super easy to do. if anyone wants some, let me know and i'll whip up a batch. as to when i can scan the article, it may be a couple of days yet. i will try to take a photo and see how that works. to the original poster, please accept my appologies if this has caused you any delays in your project !

These shims should work and come in different thickness for fine tuning the pressure. Stainless Steel Round Shims
Click on "round Shims",Choose "Bearing",Click on ".498 outside diameter."

I am actually having the same problem. I am pretty much computer stupid though. Tried saving and blowing up, with no luck.

I made this modification as the article instructed. Factory shim was .017"thick. I enlarged the ID hole of a 1/2" washer by holding it in the jaws of a vice grips and steping up in drill bit sizes to get to 3/8". Modified washer was .062" thick, added to factory shim for a total of .079". ( The article stated the slant 6 shim pack totaled .077")

I realy can't say I can feel a differance in steering effort. My steering box may have over 100,000 miles on it. I can understand it may be a little loose but I thought the effort level would increase and be felt.

I didn't post my findings as I didn't want to cast doubt on the article. The article made a statement regarding worn boxes in the first paragraph.

It is an easy modification and I hope others will post their results and the total thickness of shims used.
