Any one figure this one, had a twin screw ship which during a major engine overhaul to do stb engine top end stripped, now necessary to engage the turning gear to expose crank, some days turning gear turned crank no probs, other days seized and cannot turn at all ? Large extension bars were no help at all.called in manufactures rep, turned over, made us all look fools. Rep went back, next day seized, won't turn. Any ideas and no cheating if anyone who reads this was in enginerooms at the time. Remember ship steamed alongside no probs.
Remembering The Good Old days, when Chiefs stood watches and all Torque settings were F.T.
