CLEANING THE WHEELS & TRACK
Periodically check the engine wheels and pick-up rollers for dirt and buildup, which can
cause poor electrical contact and traction and prematurely wear out the neoprene trac-
tion tires. Wheels and tires can be cleaned using denatured alcohol (not rubbing
alcohol), which can be found in home improvement stores, applied with a cotton swab.
Occasional cleaning of the track will also help to ensure good electrical contact and
prolong the life of your engine s tires. To clean the track, use a clean rag and dena-
tured alcohol (not rubbing alcohol). Unplug the transformer and rub the rails of the
track,
turning the rag frequently to ensure that you are using clean cloth on the rails.
TRACTION TIRE REPLACEMENT
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.
1.
Remove the body shell by unscrewing the body mount screws.
2.
Remove the motor mount screw from the bottom of the truck block. Detaching the
truck block from the motor.
3.
Remove the truckside frames giving you access to the traction tires.
4.
Make sure the old tires have been completely removed from the groove in the drive
wheel, using a razor blade or flat head screwdriver to pry away any remains.
5.
Slip the new tire onto the wheel. You may find it useful to use two small flathead
screwdrivers to stretch the tire over the wheel.
6.
If you twist the tire while stretching it over the wheel, you will need to remove
and reinstall the tire. Otherwise your engine will wobble while operating.
7.
Make sure the tires are fully seated inside the groove. Use a razor blade to trim
away
any excess tire that doesn t seat itself inside the groove properly.
One set of replacement tires is included with your model.
Additional tires are available directly from M.T.H. Parts Department (Phone: 410.381.2580).
