How were the counterweights and journals supported when stored in the vertical orientation?
Without additional support the counterweights and journals will still have a bending moment imparted upon them when stored vertically. This would have a cumulative effect as you move down the crankshaft towards the ground (assuming they were stored sitting on a surface instead of hanging).
