I had an incident with my RV8 and am now in the market for a used serviceable IO-390 crankshaft . Part number 13B47219.. Can anyone advice of one available
It is actually confusing because on the experimental 390's the build they use the small main 13B cranks. It is the same crank as the 200hp 360 counterweighted engines. The certified 390 engines have a large main 13C crank. I know they make a lot more of the small main cranks so it is probably a cheaper option for their experimental engines.
