Gearbox adjusting nut seal?

I'm looking to see if the seal is replaceable on the big adjuster nut on a 1966 f250 2wd manual gearbox?

If it is replaceable, does anyone know where I can get one and what the part # might be?

I have the HCD-B1 gearbox.

NumberDummy - I have found prior posts with the part #'s for the parts in the box. I have sourced the lower seal (near the pitman arm) and the cased needle bearings locally but could you list the locations of the other replaceable parts if/when you have time please? I know you've done it a thousand times in the past but I would appreciate it.

thanks!!

What seal, what does it look like? The parts catalog pic doesn't show one.

The adjuster nut (it sets the preload for the sector shaft only) is above the sector shaft cover plate. Below the plate is the housing gasket.

I don't see any seal in this location.

Steering gear parts: New 1961/63 Uni forum / Thread titled: 64 Manual Steering Gear Box / See Post #20 (why FTE moved this thread there, I dunno, it's not Uni related).

The 1964/72 Ford Truck Parts Catalog is available on a CD from hipoparts.com for 22 bucks / Text ~ Section 35.1 ~ Page 17: Parts List #26 is for the HCD-B1 C5TZ-3504-D M/S gearbox.

Sorry about that NumberDummy, I'll try to be more specific. First off, thanks for the advice on the parts catalog cd, I have one ordered.

Secondly, the rubber seal I'm talking about is in the large adjuster nut where the steering shaft comes out of it and the steering coupler (rag joint) hooks onto the steering shaft. The large adjust nut has a rubber seal in it.

Maybe this never needs replaced as I imagine there's no gearbox fluid that gets that high.

Also, what type of fluid should I put in this gearbox? Thanks!

Thanks so much NumberDummy.

One last question. Do you know where I can get the gasket for the sector shaft plate on top of the bearbox (it uses the 3 bolts to hold it down and the plate has the sector shaft bushing in it). I just need the gasket....

however, I suppose I can cut my own gasket to work. Does it have to be a certain thickness?

thanks!

Sector Shaft Gasket = Listed in that other thread (in post #20) as a "Housing Gasket" C3AZ-3581-A no specs listed.

The 2 sector shaft bushings ride on the sector shaft itself. Dunno what that circular part is called below the sector shaft cover.

It has a basic part number of 3651 but there's a black star next to it which means: Not serviced by itself or not serviced.

But, it is furnished with the cover, according to the parts catalog pic (Illustration Section 35.1, page 2).

C5AZ-3580-E .. Sector Shaft Cover / Obsolete. If interested, let me know.

There's no "one last question" when you own "old rolling piles of misery!"
