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 on each pivot point.
The locomotive’s internal gearing was greased at the factory and should not need
additional grease until after 50 hours of operation or one year, whichever comes first.
Follow the greasing instructions below. Note that in some tightly packed engines you
may need to move internal components temporarily in order to access the gears.
1. To access the gear box, remove the cab from the chassis by unscrewing the body
mount screws as seen in Figure 8 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 (see Fig. 8).
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.
Lubricate the outside truck block idler and drive gears with grease. Use the diagram
shown in Figure 5 below as a guide and add grease to the points marked.
