Title: Pittman arm?
Post by: hertz350 on November 14, 2020, 09:35:32 PM
Was the 66 Shelby Pittman arm the same arm as used on power steering cars? Who was the supplier to San Jose in March 66? Thank you.

It was not a Mustang application.

There were no '66 Shelby's with power steering... are you asking if the Shelby quick-steer pitman arm was the same as a stock Mustang with power steering?  The answer would be no, they are dimensionally different.

The Shelby quick-steer pitman arm was a Ford piece.

Ok. What Ford vehicle did it come on and what the part number? Mine is missing. I still hope to find it. Thank you

Hi Hertz350,

IIRC, the 66 GT350 idler arm uses the power steering bushing C3DZ-3356-A, not the manual steering bushing C3DZ-3356-C or C5ZZ-3356-A.  That may be part of your confusion.

Why SAI used the power steering bushing for their manual quick steering idler arm has always baffled me.  The only thing I can guess is the power steering bushing had a larger ID and OD compared to the manual steering bushing, making it more heavy duty.  Any other guesses?

Here is the picture of my idler arm off of my March built  66 Shelby. Part number is XRR 2549. This has the bushing for the power steering idler arm installed.

Hi Hertz350,

Was the power steering bushing in the idler the source of you confusion for the power steering Pittman arm?  Or was there something else?

Both the Pittman arm and idler are 1.0 inch longer than the stock mustang pieces.  I am helping a buddy that his car has a GT350 Pittman arm with a stock shorter Mustang idler.  He never notices.  I can't imagine how this affects the steering or wears on the tires.  It can't be good.

Stay well

Cory

Yes, I was confused by why it used the same bushing as a 66 power steering idler arm. I was hoping to find that the information would lead me to a source for a Ford correct pitman arm in case I can't find mine. Now that I understand it and have the part number, I will source a Shelby pitman arm if I don't find mine. Thank you for your help.

I would loose the yellow paint.

Hi Bob,

Is idler/pitman arm yellow paint not considered correct for 66?

While the yellow paint in the reply #7 photo appears to have been applied later, when I removed the the grease and grime from the original idler and pitman arms on 6S1757 in ~1990, both were covered in yellow paint.

I've seen other later 66 original arms with yellow as well. Just trying to get a consensus.

Thanks,
Dave

This yellow paint is duplicated as to what was on this part. This is a March built car shipped on 3/31.

It is typical to see the yellow paint on ps idler arms.The yellow typical identify's ps. I haven't seen the yellow on many survivor  65/66 examples so I am a little skeptical to say it is supposed to be on every one . Given the arm was put on at SA and not Ford so there was no need for assemblyline type identification markings so it seems contradictory that there would be one. I also don't think that it was a complete assembly chassis side and arm when purchased/shipped to SA. Just individual arms swapped out with the Mustang one. I don't remember seeing any of the NOS ones that had the Ford oval trademark with yellow paint designated for power steering on them.I have several on the shelf that don't have it ether. I wasn't aware that the Ford application of the SA added longer arm was a ps one. With all that said I think the jury is still out. That is why I said that I would loose the yellow paint. I would rather be safe and not have anything then a wrong marking painted on.

Then I hope you had the presence of mind to take pictures of the part prior to restoration to justify why you did it. Some of these cars have gone through several restorations over the years.

Thanks Bob.

Unfortunately on mine I dropped the ball and did not take photos of everything during disassembly in 1990, wish I had. But, I did take detailed notes and both arms have all the correct 65-66 GT350 XRR numbers and were covered in yellow, both have a block FoMoCo logo. I've also specifically discussed this with all the previous owners and no doubt they are original. The idler was removed in 1973 only to replace the bushing with a roller bearing unit for racing, then reinstalled. The pitman had never been off the car until I removed it.

When I bought 5S275 it had a too short Idler arm but the original Pitman arm. Used a repo Idler arm until found a NOS
one in the box. Both Idler and Pitman have FoMoCo within an oval markings. The repo I had had Ford and placed in a different place on the arm, middle instead of the original towards one end. Also found a spare 65 Pitman arm with FoMoCo within an oval.

   If you don't find XRR on the forging there could be a problem. I bought several NOS loose 65-66 idler arms at Holman Moody in '77 when I was there. They all had a somewhat faint "flat", non gloss , medium blue paint mark on all of the twenty or so I found in a wire "basket". "My" guess is that those were not taken from the assembly line and therefore not "coded" with yellow paint.
As always I welcome other opinions.

I could have sworn reading in the 80s, from less than authoritative sources, obviously, that the power steering arm was used.  I think this misconception may go way back.  Thanks to all for helping clear this up.

Here is a picture showing the yellow paint on the idler arm off of an unrestored 52,000 mile Shelby built in March 66. This car was off the road beginning about about 1970 and to the present time.

6S2020 has original "survivor" pitman arm and has the original "survivor" yellow paint on it.

Have mentioned it before in other posts(maybe even a photo) on here only to be poo poo'd by the "experts"

I have lots of details from 6S2020 a car that sat in a dry long beach workshop and did not move for 36yrs 76-12

I gave up sharing these details on here long ago.........
Title: Re: Pittman arm?
Post by: J_Speegle on November 17, 2020, 11:24:22 PM
Yes 6S2020 you posted pictures at least one. Have a fair number of pittman arm pictures from additional examples built in the later half of 66 production.

While we're discussing the subject service replacement pittman identified by C5ZZ-3590-A Have a blue mark on them.

Idlers (not really the focus of the thread but have been mentioned)  can find found with the following - If they were correctly placed in the correct box or tagged correctly

C4DZ-3352-B with yellow mark
C5ZZ-3352-B with blue mark
C6ZZ-3352-B with yellow

Just sharing   

For others reading the thread these details are specific to year and application please, please don't rush out and add paint markings to you 68 based on what you read in this thread. :)

Randy,
My Idler Arm has the XRR-2549C on the same side as the Brinell Testing mark.
It looks exactly the same as Howard Pardee's on 5S350 that I believe he bought new.

 Correct! Mine is the same way. The current one on 477 is one I got from H&M in '77. I did switch to the MOOG "K451" roller bearing kit 40+ years ago when they were plentiful. Because of drag racing , I have only added a couple thousand miles in all those years. Steering effort was less with the bearing vs the rubber bushing.
   I haven't seen any "reproductions" with the hardness test mark. IMHO they appear to still be made by the original supplier.

For some reason I thought of this thread the other day and thought that I recalled seeing some yellow paint on the pitman arm on 6S1575 - 2nd or 3rd week of March 66 build.  I got under the car today and cleaned up the part and found more yellow paint than was apparent before the cleaning.  I assume this is an original part but have no way of verifying that.  Just thought I would add another data point and picture to this thread.
