As I said previously the weak link on these units seems to be the drum that blocks the outlets to direct the flow. I've heard from others that the drum breaks right where it attaches to the gear drive, seeing as this is the thinnest part I figured I would make a brace for it.
Here is the piece I made next to the drum. If it looks like the hole is too large, there is a boss around the hole and this fit snugly against it.
Here it is in place ready to be glued.
