Brendan -

That bracket is a support for the nose drive against downward pressure applied by belt tension..... the nose drive is fine - I think the issue is with bearing failure at the rear of the rotor housing.

Ed -

I expect I'll have more to do than just replace the bearings. I'll do a complete rebuild including the coupler, oil change and whatever is needed on the rotors. If the bearing rollers did indeed go through the engine, the rotors may be trashed - and the engine will need work - at least the heads will have to be inspected.

Since it's a hobby truck, I don't mind the work.... I even enjoy tearing it down to find out why something happens - I'm always curious to see what caused a problem and learning how to avoid it in future efforts.
