Cracked case 510LC

Pic shows inside of a liquid cooled 510 left case half.
Would you say that crack is reason enough to scrap it?
It goes through to the other side as well.

I'd get it welded ?

That is hard to tell what I am looking at Can you put a picture zoomed out to show the whole case is visible. I would say that is basically scrap. Cast aluminum doesn't weld like aircraft grade.

It's at the hole for the shifter mechanism/lever axle.
Im thinking it's difficult to get it good enough since I reckon the force from the secondary shaft pushes there.

That picture most likely is an 85 and earlier 250 two stroke. I see it really was inside the case. Most problems to put a bike or engine to parts probably are not this issue. The one at the swingarm pivot more so on the other side for case issues.

Yup, it's from a '87 2T manual. Didn't have any good 4T pics (I'm at work..).
I've not much too lose trying to get it welded as it's an extra pair of cases I've got. Still, always nice with spares!

The manuals do tend to use pictures from years prior. Rather significantly different in the later auto bike. Perhaps that damage could occur forcing improperly aligned things together.

The damage is most likely from a thrown cam chain wrecking havoc in the clutch case.
