gearbox. Amphibionics

Place a pinion gear onto the end of each motor shaft so that the
end of the shaft is level with the end of the gear. Install each motor
in the gearbox by sliding it into place, as shown in Figure 6.6. The
plastic clips on the gearbox body will snap into place and secure
the motors in position.

When the gearbox is complete, mark each shaft at 5/8 of an inch
from the body and cut with a hacksaw. The finished gearbox,
ready for use with Crocobot, is shown in Figure 6.7.
