the truck block and lightly coat the motor worm gear and bronze drive gear
(in the truck block) with grease. Reassemble the truck and motor, being
careful not to pinch the pickup and ground wires between the truck block
and motor mount. Repeat the procedure for the other motor and truck and
then reassemble the chassis to the body. When reassembling the chassis and
body, be very careful that the lighting wire harnesses are not caught
between the body and chassis as this can lead to a short which may damage
the electronic circuit boards beyond repair.
In addition to the truck block internal gearing, it is a good idea to lubricate
the outside truck block "idler" and "drive" gears with grease. Use the
diagram shown in Fig. 3 on pg. 5 as a guide and add grease to the points
marked with a "G".
Periodically, check the locomotive wheels and pickups for dirt buildup as
this can significantly affect the engine's ability to perform properly. Dirty
track and dirty wheels can cause both poor electrical contact as well as poor
traction, especially on elevated track sections. Finally, dirt and oil build up
can prematurely wear out the neoprene traction tires.
Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on
each power truck. While these tires are extremely durable and long-lasting
there may arise a time where they will need to be replaced. Should this
occur, you will need to remove the trucks and truck sides on the truck block
from the chassis in order to slip the new tire over the grooved drive wheel.
We suggest you follow the disassembly instructions found in the
Lubrication section on the preceding pages to dissemble the chassis and
truck blocks from the body.
