We have experienced a similar issue unrelated to the manufacturing of these gearboxes. Cantilevering the "El Toro" intakes last year put a LOT of forces on the output shafts that they were never intended to have. In fact, I am amazed they held together as well as they did! Sure, it is simple to replace the output shaft and snap ring. The problem is, they seem to know when the worst possible time to fail is.

I would love to see these plates. You never know when they may be needed again. A CAD file would be even better!!
