4000 brake cross shaft part number help

Pulled the cross shaft out of my 1970 4000 last night to replace bushings and oil seals. It's worn a bit more than I had hoped it would be. In trying to decide next steps, I went looking to see what a new shaft would cost if one was available.

I'm having trouble figuring out the part number. From the New Holland parts site, under Brakes->02A02 Brakes and Brake Controls, the shaft is shown in the schematic as part 26. (Mine is the pre-1972 version shown in the call-out box, with the LH brake lever welded to the shaft).

Unfortunately both the New Holland site and the parts manual I have show part 26 as C5NN2473F, which is just a seal.

Any idea what the actual part number might be?

Thanks in advance!

If this the call-out box you're talking about:

My parts manual shows 3 part numbers for item number 26 in that picture, and they are all listed as "Pedal Shaft Assy." each is for different year ranges and applications. C5NN2473F is for 01/01/1965-07/31/1967, all models. C5NN2473F is for 08/01/1967-10/31/1972 without a 10 speed (S-O-S) transmission, and C5NN2473H is for 08/01/1967-10/31/1972 with a 10 speed (S-O-S) transmission. Full text of each of the 3 listings for part number 26 are listed below:

26 C5NN2473F 1 Pedal Shaft Assy., Includes: Ref. 26A, When replacing Shaft Assy., use (1) Ref. 26B, (2) Ref. 30A, (2) Ref.
30, Ref. 26C, Ref. 26E & Ref. 36., Years: 01/01/1965-07/31/1967

26 C5NN2473F 1 Pedal Shaft Assy., L/10 Speed, Includes: Ref. 26A (Not Shown), No Longer Serviced, Years:
08/01/1967-10/31/1972

26 C5NN2473H 1 Pedal Shaft Assy., W/10 Speed, Includes: Ref. 26A (Not Shown), When replacing Shaft Assy., use (1) Ref.
26B, (2) Ref. 30A, (2) Ref. 30, Ref. 26C, Ref. 26E & Ref. 36., Years: 08/01/1967-10/31/1972
 
Thanks for posting the image and data -- yes, that's exactly the diagram. My tractor is a 1970 8-speed, which would be the middle of the three, C5NN2473F.

What's confusing me is that when I search for that part online, the only thing I come up with is a $2 seal. Moreover, the online New Holland parts manual lists C5NN2473F not as a shaft assembly, but instead as "SEAL PROTECTION". I'm wondering if the parts manual is just wrong, or perhaps it's just that no one sells this particular shaft.

The ytmag parts store has the 3000 cross shaft, but I can't find *anyone* online who has the 4000 cross shaft.. not mine (assuming it's C5NN2473F) and not the other one (the non-callout version) D9NN2N337DA.

Hoping someone has been down this road before.. thanks in advance for any advice.
 
I think I figured this out.. on the theory of "if no one is making an aftermarket part, you probably don't need a new one" I settled for new bushings and new oil seals. Worked like a charm.. no more leaks!

Reading the parts manual again I think the idea is that if you have the older shaft and it needs replacing, use the newer shaft. But I don't see anyone selling the newer shaft either. Not listed in the sparex catalog even.

Thanks!

I was going to suggest trying the newer one next. It looks like the only difference is the older one has the lobe with the hole for the left brake rod as part of the actual cross shaft itself, and the newer one has the lobe as a separate set of parts (26C and 26E) that attach to the cross shaft, which actually looks like it would make it easier to adjust the play in the left brake pedal.
