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. Please use the following instructions to replace the
traction tires.
1. Turn your engine upside down.
2. Remove the two Phillips screws that attach each truck side to the truck block.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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
