Lubrication and Greasing Instructions

The engine should be well oiled and greased in order to run properly.

You should regularly lubricate the pickup rollers to prevent them from

squeaking. Use light household oil and follow the lubrication points marked

“L” in Fig. 2. 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 screws from the chassis, as seen in Figure 3, then lift the body

away from the chassis.

2. Remove the black Phillips motor mount screw located on the bottom of the

truck block underneath where the pickup roller sits.

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.
