Seemed like a good idea at the time, use the 9000lb winch to remove the crankshaft vibration damper from the end of the crankshaft. It was good and stuck, so a lot of effort seemed ideal
Untill it sheared the damper off, leaving the collar behind on the end of the crankshaft. Nasty cheap castings they use these days.
Had to slit with grinder what was left of the damper off and break it with a chisel. The culprit? bit of rust on the end of the crankshaft...
