Mark and Mark and netters I agree whole heartedly. And if I find that the cranksahft that WW sold me is NOT nitrided I will have it nitrided.
What I should have said is that it is premature to draw conclusions that nitriding will do anything to address the broken crankshafts in OUR CASES. If nitriding is known for adding durability to a crank then it is a good thing regardless, I agree. But I believe there is ALOT more investigating to be done on this issue, then just treat the cranks and re-install and fly. That is all I wanted to make clear. With the volume of knowledge and numbers of engines this group has collectively, a collaboration should be able to yield a great deal of useful information in this pursuit that all will benefit by, including WW. I would like to stimulate all of us to work together to go beyond where WW is now with this and SOLVE this issue, not wait on him to discover it. By WW's words himself the problem did not begin until after 2004 when his version engines began to become widely used. What has been changed from the way they were previously used in airplanes prior to 2004? A good starting point for understanding where the problem is, is to look at the way the engines were installed and used prior to WW, and compare to our engines now. Then we know what needs to be tested like Ron Eason suggested, and we can save alot of time and energy, and money. Like Ron said, maybe the way Bill Clapp and Steve Makish flew their engines has much more of a factor on the cracks then the machining. Yes we all could benefit from better cranks, but we should not stop there. We need to find out for sure why these crankshafts are/were cracked. That is my main point, take it for what it is worth...
