(with typical orientation of mounting) In fact, after drilling out the holes for a 1/4-20 tap, the holes were still not perfectly circular, that's how much damage had occurred. We noticed this issue right before eliminations at Fall Fiesta.

Iirc the bearing block is geometrically/mechanically locked in position in reference to the gearbox plate. Aren't those screws only being loaded in tension to clamp on the tube?
