I asked this question on another forum and got 1 response which i'm leaning towards being correct. I am not trying to offend anyone by not instantly taking ones word for it but re-splitting a tractor is a pain and would like more verification before I do so. When replacing the transmission input shaft in my cub I found the front bearing to be sealed on one side and installed with the seal facing the trans. I would have thought the seal would be away from the oil side so I reversed the bearing on the new shaft, which is apparently incorrect. My question is will there still be enough splash lube to oil the bearing or will I in-fact have to go back in and change the bearing orientation?
 
seems to me that reversing this bearing will allow shaft to move forwards slightly, therefore, the pto shaft will not engage, properly, after a period of time.

dale shaw, on farmall cub rescue, can tell you more. or correct my reply.
 
Not the right bearing. The right bearing does not have a seal on it at all. If oil cant get through the bearing, the oil seal will burn up because it isn't getting the lube it needs as well.
 
I stand corrected, The bearing should be without seals either side. The real seal will fail with no lube. Packing the space between the bearing and correct seal shown in the parts catalog would work in the same way putting two seals on a shaft at other locations works. One could also remove the seal from the bearing. Jim

It's POSSIBLE the O.P.'s bearing has a "SHEILD", rather than an actual "seal".

That's COMMON with transmission bearings.
