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. 4), 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. 4 for which screws you
must remove to do this.
Once the truck sides have been removed:
1. 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.
2. 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.
3. 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.
4. Make sure the tire is fully seated inside the groove. Use a razor blade to
trim away any excess tire that doesn’t seat itself inside the groove properly.
5. Reassemble in reverse order.
One set of replacement tires is packaged with the model. Additional tires are
available directly from the M.T.H. Parts Department (phone: 410-381-2580;
fax: 410-423-0009; e-mail: [email protected]; mail: 7020 Columbia
