Seeing this makes me like the VersaPlanetaries even more. Their manufacturing tolerances and material consistency must be very good for all four pin holes to fail at about the same time. This is assuming that the OP exceeded the torque ratings on the gearbox. I'd love to hear how this happened.

It's more likely that one failed, then the rest did in order.

If one had failed before the others wouldn't you expect to see differences in the breaks or other damage elsewhere in the gearbox?
