Inner axle seal question

My tractor is a 1951 8N (Sn 432525). I am now working to put the axles back in place with new seals. Trouble is, there doesn't appear to be anywhere for them to seat. No milling in the housings, no milling on the axles. The only picture I have of the area is of the axle end with the bearing. What should I be seeing in the "trumpets" for the seals to fit into?

Thanks, guys.

Re: Inner axle seal question (and outer seal, too)

Noob here - patience appreciated while I learn correct etiquette for this particular forum.

Great info in this thread on axle seals - thanks.

So, where do the 'outer' seals go? Somewhere very near to the hub, I presume.

Do the 'inner' seals go near the diff end of the trumpet, or near the hub end of the trumpet?

I'm about to do the hub replacement procedure on my '51 8N s/n 434,xxx and I'm not sure if I'll need both sets of seals or where each set goes.

Where are the casting dates located on the trumpets, and what is the cutoff date for needing / not needing the inner seals?

Thanks in advance!

forgot to ask:

How is the axle retained in the diff / trumpet? Is it a 'C'-clip on the diff end of the axle or some mechanism on the hub end?

Thanks!

n/m, I think I can determine that, by the direction of the cone bearing on the hub end of the axle, that the axle is thereby retained within the trumpet. That bearing is then pre-loaded by the axle nut outside the hub, thus holding the axle firmly in place on its outer and, and it is stabilized at the inner end by the differential side gear. Therefore, the axle can only be removed by removing the trumpet, correct? Furthermore, the inner axle oil seal (if my trumpet casting in fact contains one) cannot be replaced without removing the trumpet and axle, right?

Thx
