pinion gear double cup bearing issue

[Lee Mitch]

In preparation for a Mitchell overdrive I removed the torque tube from the banjo and the drive shaft with pinion gear and double cup bearing just fell out of the banjo housing. I'm pretty certain that is not supposed to happen! There is some scoring where it appears the double cup bearing was turning inside the banjo. What say you? Is this a complete replacement of the double cup bearing and the banjo?
