Good point. That raises the other question: how would the shaft get in there to begin with?
The lightening holes might let you get away with not removing the gear. But IRL if I made this, all bearing flanges would be on the outside and/or I would use riveted bearing blocks to save space inside the tube. That particular spot is actually easy to put at least one of the bearings on the outside because I have space in there.
