tranny seals leaking on M

Could anybody tell me how to change what appears to be the 2 seals on the transmission side of the casing. I guess were I'm talking is under side of tractor (no belly pump) I've taken the cover off to change my clutch and it looks very wet inside not so much on the clutch side but the side were the shaft from the crank goes into the trans. housing and possibly the one underneath it as well. I'm kind of new at this and assumed that my clutch was shot so I ordered a clutch kit after trying repeated adjustments, and now I noticed how wet (oil) it is and wonder if this is the cause of the clutch slipping and if they should also be replaced? There isn't any oil on the pressure plate just kind of grimmy if that is any way to describe it. I put any load on the tractor and it just sits there in gear not moving with no change in rpm's. Any help would be greatly appreciated. Thanks....
P.S. sorry about writting a book>>>>
 
That isn't a book. The two seals are replacable from under the tractor, as is the clutch PP and disk. Take apart the coupling at the transmission. (take a photo to assure correct assembly) Remove the Throwout components. remove the drive yoke and the retainer and there it is.
The bottom seal is taken out after the drive coupling is unscrewed with a hard square steel bar (lefty loosy) The clutch is toast. Clean the oil off of everything, and be sure to replace the pilot bearing in the center of the F/wheel. There are pictures in the archives, as well as a vast number of posts on this topic. Good luck JimN
 
The original part numbers are:
43359D upper seal
50839D lower seal

The 2 gaskets that go along with them are:
47916D
43334D
