As the case distorts the crown wheel moves away from the pinion gear to move the load out to the pinion tooth tip. So the pinion breaks a tooth off first, keeps rotating to damage the crown wheel teeth. The next pinion tooth is then impact loaded to break off next, until there are a number of pinion teeth off.

Not a correct answer.
The exact loading being questioned is the lateral forces involved, as would be required to distort the case. Not subsequent loading on the pinion teeth, which involves gear diameters.
