Help with 2n tranny

I have a 2n with 3-speed with sherman step-up tranny.Had a noise coming from inside tranny and have isolated that to a bad counter shaft.I also had a little bit of tranny oil leaking from cotter key hole in center section. I thought I would try and fix this while i"m in there. Am I right in thinking there is no oil seal for the main drive shaft where it comes through the housing when you"re using a sherman? What would be the likely source of a leak from the sherman tranny? Thanks for any help,

the sherman uses the exact same input shaft seal that the regualr input shaft would, which it replaces.
 
Thanks SG
I found that seal and also found another that goes on the shifter rail. I did what I should have done first and went to John Smith's sight,what a wealth in information! Now all I got to do is order the parts and I'm back in business.

Just for your info,

If you plan to replace worn parts (bearings, shift collar, etc) in your Sherman, John Smith and Red Rock Manufacturing (Phil Smith) will probably have what you need.

If'n you need to replace a badly worn Sherman counter-shaft, The Old Hokie can help on that too...

If you replace the Sherman countershaft and find the case is a little oversize, then use some loctite bearing retaining compound at the shaft to case mating surface upon istallation to seal that from a possible leak.

I did not seal mine, so I have a small seepage that makes its way out the cotter key hole below.
