so you sheared the bolt and the key. No way is that crankshaft not tweaked as a bend or twist. The key flat side usually goes into the crankshaft. Make sure the sparkplug wire is out when you work on it. Torque the bolt to specs. Then make note where one end of the blade is close to the edge of the mower housing, rotate it 180 degrees to be sure it is in the same spot. If the mower runs poorly or won't start, suspect the flywheel key may be sheared too. If it vibrates badly, then the crankshaft is warped. If that is the case, you may find another model with the same engine as a donor on FB Marketplace.
