Personally, I feel nitrating is additional insurance and I would not fly without having a nitrided crank even with the fifth bearing. Why take the chance? It does not cost that much to have it done.

I sure hope so but only time will tell. Mark Jones ________________________________ Hi Mark J & L, I purchased a Corvair engine from Larry Flesner during Mt Vernon 2008. I will be building this engine for aircraft use one of these days, after I see how all you 5th bearing guys hold up. I am wondering what any of you 5th bearing flyers think about the "necessity to nitride the crank" with the addition of the 5th bearing? My thinking is if the previous basic problem was bending loads breaking non nitrated and nitrated cranks then what good is nitriding? Since you Marks have noticed major differences in the operating smoothness of your engines during all phases of flight with the added 5th bearing, maybe there is no need to go to the expense of that crank process. Just wondering what you think about this. Thanks Larry H. After almost two full months since my crank breakage, "Six Mike Juliet" flew again this morning with the new Dan Weseman fifth bearing installed. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to [email protected] please see other KRnet info at http://www.krnet.org/info.html
