[quote]QUOTE: Don't buy into the rumors that GE locomotives do this on a regular basis , I have patched 100s of EMD crankcases after a rod came through the block. Working on 645 , 20 cylinder engines I have seen lots af broken crankshafts too . I have spent enough time around the SD80-mac and the Sd -90 mac to know that they have some serious electrical issues. This particular GEVO had connecting rod failure, this is so far the first one I have heard of , doesn't sound to me like Ge has a quality problem yet . In fact if you ask people in the know, EMD is suffering the bulk of the QC problems. [/quote] I don't think GEs do this on a regular basis. But this connecting rod failure was just a freak thing. It could happen to any engine. EMD ain't perfect- a MRL SD70ACe had a sensor go defective and then it can't tell if the wheels are slipping and then the wheels started slipping and it burned the rails. But after that MRL still bought SD70ACEs. GE is just trying to get too much power out of 12 cylinders. It can be done, but I think they should have done a little more testing. Just looks at ALCo PAs. They had one 2000 HP engine which was ahead of it's time (as far as how much power can be extracted) they threw rods quite a bit. Again, if they had been tested a little more this MIGHT not happen.
