CLEANING THE WHEELS & TRACK
Periodically check the locomotive wheels and pick-up rollers for dirt and buildup, which can
cause poor electrical contact and traction and prematurely wear out the
neoprene traction 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 denatured alcohol
(not rubbing alcohol)
. Unplug the transformer and rub the rails of the track, turning the rag fre-
quently to ensure that you are using clean cloth on the rails.
TRACTION TIRE REPLACEMENT
Your locomotive is equipped with four neoprene rubber traction tires on the rear pair of each
set of flanged drivers. While these tires are extremely durable, you may need to replace them at
some point.
1
.
Remove the side rods
(the rods that connect each drive wheel to the other)
from the
wheels in order to slip the new tire over the grooved drive wheel. This screw can be
loosened with a 5mm nutdriver.
2
.
Make sure the old tire has been completely removed from the groove in the drive
wheel, using a razor blade or small flathead screwdriver to pry away any remains.
3
.
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.
4
.
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.
5
.
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).
