Saw this reported in the US today.........
It's been a tough few months for the folks at Teledyne Continental Motors. For most of 1998, a hydraulic press used to assemble crankshafts for its most popular engine series -- the 470, 520 and 550 big-bore sixes -- was misadjusted. The press managed to damage the super-hard nitride coating on numerous crankshafts, producing a stress riser. In turn, a few of the crankshafts failed, resulting in engine failure. Thankfully, there were no serious injuries -- except perhaps to TCM's bank account and to its reputation.
