Figure 7. Locations of Greasing Points on the Locomotive
Lubricate the outside truck block idler and drive gears with grease. Use the
diagram shown in Figure 7 above as a guide and add grease to the points
marked with a "G."
Periodically check the locomotive wheels and pickups for dirt and buildup,
which can cause poor electrical contact and traction as well as prematurely
wear out the neoprene traction tires.
Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on each
powered truck block. While these tires are extremely durable, you may need
to replace them at some point.
First, remove the truck sides from the truck block.
To do this, turn your engine upside down. If there
are visible Phillips screw heads between the truck
frame and truck block (see Fig. 8), go to step A. If
not, go to step B.
A. Remove the two Phillips screws that attach the
truck sides to the truck block.
B. Remove the trucks from the chassis and the
truck sides from the trucks in order to slip the new
tire over the grooved drive wheel. See Fig. 8 for which screws you must
remove to do this.
