Other than that, there should not be an issue with the retaining screws being a bit loose.

Yeah, I doubled checked that the middle gears were oriented this way, no problems there. As far as I could tell only one gearbox reacted differently to loose or tight retaining screws, the rest just won't spin by hand regardless of screw tightness.
Dissembly and reassembly would often allow me to turn one by hand, but I haven't found a method that works every time.
