Well at least you've got others for reference on getting the alignment correct. What I do is scribe a line between the meshing teeth, and also marks between the gears and the chassis. Then take photos and video during the teardown. I also like to take a 9 volt battery and drive the mechanism all the way to one end or the other so that there's less room for error on gear position when I'm assembling.
I've seen some of these gears starting to warp with age, or the bearing holes become oval or loose especially when they are under spring pressure.
