Bill; Nitriding is similar to case hardening and may be thick enough to not
crack through. What you are calling caged needle bearings I think is what I
call roller bearings. They are in split cages, For the thrust bearing I was
told Ball bearings are used with the races that curve around the side. I
don't know what they are called but they take radial and thrust loads. I
guess your injectors would be on the bottom of the crankcase. Kind of strange
but doable. The price is the big holdup I see. Rich
