The clustergear have only 2 pairs of bearing at each end; at the center is bearing-spacer (red arrow). If clustergear (housing) or countershaft broke, you can strengthen it by remove the bearing-spacer and add roller-bearing instead. I have not yet done it, nor heard anyone done it, just a thought.

However, from your picture, not the clutergear's housing broke but the cluster's gear itself. I have no idea how to strengthen it.

Btw, I love 720 HP :burnout: .What motor is it?
