Brake seal on Farmall H?

I removed the brake drums from my 1942 Farmall H and found oil leaking from the nearby transmission. How do I repair this? I can't see a seal of any sort. Does the splined drum act as a seal? And what do you do if it's leaking? I noticed a cork washer on the bolt which holds the drum fast ... is this all there is acting to keep the tranny oil from leaking out?
 
There is a large oil seal in there, it seals against the hub of the brake drum. You will have to pry, hammer, chisel it out :)then replace with a new one, any good automotive parts store can cross the number on the old seal and get you a new one. The old seal is about 3/4 inch thick while a new one will be about half that thickness, that is not an issue, tap the seal in until it is flush with the outside of it"s recess. The cork washer keeps oil from leaking out between the splines.
 
These seals can be a little darling to get out. I drill a small hole in about 3 places in the seal then I take a little hammer puller, screw it in the hole and tap it out. I suppose you could screw a screw in there and pull it out with a crow bar.

Make sure you do not deface it so you cannot read the numbers on the seal for cross matching. I wrote the numbers down around here somewhere but now I have forgotten where it wrote them.

If it is original, it may be a double seal - 2 seals in a single shell. and like the toehrs have said, it is fun. The gasket under the botl holdignb the drum is needed to.

yep you need to change the seal and if you can't get the original seal just put two thinner seals one the lip inward, the other outward. I would also replace the oring if it is leaking. If you remove the carrier that the seal seats into don't forget to remove the big bull gear out of the way otherwise you will break the carrier... don,t ask how I learned that lol
hope this help and good luck
 
You say you have the seals. I did manage to remove one seal in about 8 pieces. It was a bear - concluded that it was physically impossible to remove in one piece. The double seal has the number 48498D on it and some letters C/R ... is this the replacement seal you say you have?
