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.
Remove the two grease port screws (two per gearbox). Use a grease tube dispenser and
put a small amount (Approx. 1-2 mL.) of lithium-based grease into each grease port.
Replace the screws.
Lubricate the outside truck block idler and drive gears with grease. Use the diagram
shown in Figure 10 below as a guide and add grease to the points marked.
