[QUOTE="Tazza, post: 71596, member: 82"] The bolts, are they the ones holding the flywheel to the engine or the 4 to the U-joints? If it was the flywheel to the crank, i thought there was like a key pin that aligns the flywheel to the crank. I honestly don't believe there would be enough torque from the engine to sheer all those bolts and pin in one hit. I'd go with the idea that the bolts were not tightened up properly or over tightened and were so stressed that they just failed. I don't think the freight company caused that damage, they did the other damage, but i can't see it being the bolts As the pump turns, i'd like to rule that out. There are parts inside that are a lot weaker than the bolts that broke. These would fail before the bolts. [/QUOTE]
