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.

Have our prayers all been answered with the fifth bearing? I sure hope so
but only time will tell.

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.
