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. 7), go to step A. If not, go to step B.
A. Remove the two Phillips screws that attach each truck side to the truck block.
B. Remove the trucks (see page 11) from the chassis and the truck sides from
the trucks in order to slip the new tire over the grooved drive wheel. 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:
