Maintenance
The engine should be well oiled and greased in order to run properly.
Regularly lubricate all axles and linkage components 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.

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. Remove the eight Phillips screws from the chassis, as seen in Figure 3, then lift the
body away from the chassis.
2. Remove the truck blocks from the chassis by unscrewing the black Phillips motor
mount screw on the bottom of each truck block, as shown in Figure 3.
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.
