So at the ride last night I broke my Grande. Hard. I thought it had seized, but it didnt. Got home and took it apart, and turns out my TOP crank has sheared itself in half right were the shaft meets the crank half. It also seems that the flywheel side bearing has way too much play. So the question is: did the bearing go first, or did the crank damage the bearing when it sheared? What can cause a sheared crankshaft besides crappy metallurgy? I dont want to order a new one just to do it again.
