Had a Jred 2171 that came in here a while back with almost identical damage but on the clutch side. Bearings rough also. Turned out that the ball retainer in the clutch side main failed. (Metal retainer not plastic) Got caught (I think) between the skirt and the jug on the up stroke more than once. Most of it was still in the crank well. Also scored up the bottom of the crank well.
