Re: Transmission output flange fell off Yanmar 2QM15 - Theories re: why?
The spline on the shaft looks serviceable still.. that's the good news, I think. But it's very hard to believe that the mating spline on the original coupling wouldn't have been similarly matched for full engagement so now one has to wonder if the damned thing didn't machine itself... But it wouldn't happen overnight and I'd have thought you'd have noticed some slippage or unusual behaviour/noises prior to failure.. it's still hard to credit.
Odd problem. Would there be an original part number to use on an image search?
