[AT] Another Oliver practical technical question for the list

I have a 77 diesel and am not sure how a crack like that started. There
is a web/baffle in the case near there, but I don't think normal heavy use
could start it. - it would take abuse - serious abuse, to do it. I am
guessing it flipped over at some point in time in its life and now just
time and wear made it more noticeable or got it started. Mine isn't a
long axle, so I could be wrong.
If you are sure the crack is recent, structural, and serious, get another
tractor. There is no repairing it in a way that assures operator safety,
especially not cheaply. Personally, I'd mark it with an engraver and watch
it closely. Sometimes vibration or a recent pressure washing, or a good
long use after after a period of dormancy, will open an old leak back up
making something like that appear recent when it really isn't
