12 Premier Big Boy Steam Locomotive
Maintenance
The engine should be well oiled and greased in order to run properly.
You should regularly lubricate all side rods, linkage components and
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.

Figure 5: Removing The Body
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.
To access the gear box and axles, do the following:
1. Turn the engine upside down.
2. Remove the Phillips screws (marked “GREASE”) located at each set of wheels and
under pick up rollers (Fig. 6).
3. Use a grease tube dispenser to put a small amount (approx. 1-2 ml.) of lithium-based
grease into the screw holes.
4. Replace the screws.
