Reinstallation

3) Place the white gear on the motor shaft and secure it with the 7/64” Allen screw.
4) Plug in the ribbon cable.
5) Mount the motor/ bracket assembly using the two 7/16” bolts. Don’t tighten them
yet.
6) Slide the assembly up so that the gear mesh is tight, then back off 1mm and
tighten the 7/16” bolts. (Ideal gear mesh will allow a piece of paper to pass
through the gears, wrinkling it, but not ripping or puncturing it.) Manually move
the robot front to back the full length of the track to ensure there is no binding or
skipping of the new mesh adjustment.
