5 ton PTO out put seal

First, I did a search.
Can anyone give me a civilian part number for the 5 ton PTO output seal on an M39 deries which should also be the 800 series PTO for the forward facing out put shaft for the winch driveshaft?
I bent my drive shaft Saturday pulling out a pickup built on 5 ton axles running 60 inch rice and cane tires in a heck of a mud bog. I have a shaft but need to replace the seal in the PTO.
As a matter of interest, I was pulling in high retrieve because I was having trouble finding loe speed and it was a terrible hard pull, all my fault on bending the driveshaft. The shear pin is aluminum and it did not break, only has a small bend in it. I'm pretty sure it is a military pin but there is a chance it might be one of the ones I built. I keep the RPMs around 1000 when I do recoveries .
The existing seal is a Trostel 256-148-8


Thank you, JT

I have this seal number for an M35a2 PTO output shaft. CR Seal PN 12530

From what G has posted, both the 2.5 ton and 5 ton PTO shaft diameters are the same. The shaft lengths are different.

John, sorry for not responding immediately!
YES, for the two PTO's sharing the same seals.
Output shafts are different but still the same diameters; 1-1/4" where the seal rides on - (pic w/ arrows).

The seal in question would be a Timken 471787; or better their wider, encased one 410244. Both are double lip type, which I prefer over the TCM (single lipped) shown in the last pic.

Dimensions, below...


G.
