Crank hub replacement

[sapote]

IMO A single bolt long snout design requires an interference fit hub to work properly to transfer torque and because without interference if it slips can easily shear keys/dowels over time but complicates the assembly and disassembly but this approach is used on many engines.

Do we have incidences of the single bolt and woodruff key issue? The key and keyway is a very tight tolerance machined parts.
The 4-bolt arrangement has the sprocket cantilever on the crank face and inherently seems less stable than having the sprocket carried by the crank long snout. It's an interesting engineering problem.
