Lubrication and Greasing Instructions
The Subway Set should be oiled and greased in order to run properly.
You should regularly lubricate all outside idler gears 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.
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. Use lithium-based grease and 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 Phillips screws from the chassis, as seen in Figure 3, and then
lift the body away from the chassis.
2. Remove the Phillips screws from the chassis, as seen in Figure 3, and then
lift the interior away from the chassis.
3. 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.
