Yes, I actually wanted to do something like this in the beginning, but I did not find a way, how to calculate the required diameter of such a pin - first of all that depends on material to be used (well, its shear strength, to be more precise), which I also do not know, what would be most suitable. Replacing a pin on such an occasion is acceptable, so no worries about any inconvenience for operator. Overall solution seems to be pretty easy to implement - use such a pin instead of key between sprocket and output shaft of gearbox. There is max torque allowed, there is radius of the shaft, which allows to calculate the shear force easily, but do not really have any idea, how to proceed from there.
