M500 drive sprocket question

[General Chaos]

I was replacing the right side variable speed jackshaft bearing and noticed the sprocket on the rear clutch was really worn. Even right into the plate the clutch plate seats against. The front sprocket and chain looked fine. Anyone know why only one sprocket would wear that much?

Misalignment or the other sprockets have been replaced.

I figured it out this morning right when I woke up. The bearing was shot on the jackshaft so that sprocket was tilted up. As the chain ran to the first sprocket it was misaligned.
