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.
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 5 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 Figure 5).
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.
