Yup, btdt at least twice now, but I didn't know that forcing the
trans/engine together was another possible cause... I've also read that
uneven wear in the clutch lever forks can cause p/b failure, which leads to
input shaft seal failure, etc. Since then I've always replaced or at least
evened out the clutch lever forks.
But keep an eye on things, and it's possible to save the clutch from oil
contamination if you catch signs of oil leaking at the bottom of the b/h
soon enough. (you may also feel the clutch grabbing erratically).
Tomorrow I plan on pulling my dash, so we'll see how fun that is compared
with the trans swap... :-)
