Yanmar 1500D hydraulic fluid leaking.

I know you like to keep going to the hyds system for some reason. it really really really sounds like you want to take your hyds apart.. so.. you might as well start there, as you mention it in each post.

once you get that done, then come back and we can talk about your tranny input shaft.

going down hill puts oil against the seal.. if the seal is bad.. that's when it leaks.

as to a bearing be bead.. that's conjecture. We KNOW a seal is bad because of the leak. We are GUESSING it is a bearing because of the bad seal, and metal. it could still just be a chewed up seal that was installed incorrectly that then wadded up and spun, etc... won't know anything till you get the bellhousing open to see the input shaft.

But no problem.. you go take your hyds apart and get that itch scratched.. then we can work on your input shaft.

So you're telling me I put that seal wrong or incorrectly...ok...guess I'll have to do that again. I'll be a professional, I've taken it apart two times already. This will be my third time.

I'm not saying you did it wrong, just saying that without putting eyeballs in there, we can only make educated guesses.

Oil leaking from a bellhousing drain that isn't engine oil I usually trans input shaft related.

A few machines have Hyds in that area, but that sort of leak would be pressure, and you would loose oil constantly, not only when nose down. If it were suction, same deal, constant problem, not a leaker, but a sucker, usually foamed oil, loss of 3pt, loss of prime.

Machines with a powershift tranny can have charge pump leaks, etc.
