3. Once the motor mount screw has been removed, pull the motor away from
the truck block and lightly coat the motor worm gear and bronze drive gear
(in the truck block) with grease (see figure 3a).
4. Reassemble the truck and motor, being careful not to pinch the pickup and
ground wires between the truck block and motor mount.
5. Repeat the procedure for the other motor and truck
6. Reassemble the chassis and body, being careful that the wires are not
caught between the body and chassis, as this can lead to a short that may
damage the electronics beyond repair.
It is also a good idea to lubricate the outside truck block idler and drive gears
with grease occasionally. Add grease to the points marked with “G” in Figure
