Spun rod bearing

[C3L1CA]

Wouldn't one want to figure out why a motor spun bearings in the first place?

I thought it was too risky to just get the crank polished/cut and throw in the proper bearings. Maybe it was just improper install which caused the damage or something else? I'm sure it would have been fine with getting the crank polished but it would have been too much money to fix it for what a 7 bolt was worth to me.
