Maintenance
Lubricating and Greasing Instructions
The engine should be well oiled and greased in order to run properly.
Regularly lubricate all axles and pickup rollers to prevent squeaking. Use light
household oil, such as that found in M.T.H.'s maintenance kit. Do not over oil. Use
only a drop or two on each pivot point.

1. To access the gear box, remove the cab from the chassis by unscrewing the body
mount screws (located underneath the trucks) as seen in fig. 9 and lifting the cab
from the chassis.
2. Once the cab is removed, remove the trucks by unscrewing the black Phillips motor
mount screw located on the underside of the drive trucks (fig. 9).
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.
4. Reassemble the truck and motor, being careful not to pinch any wires between the
truck block and motor mount.
5. After repeating the procedure for the other motor, reassemble the chassis and body,
being careful that the wire harnesses are not caught between the chassis and body,
and reinstall the body mount screws.
