R-17 Subway Set with Proto-Sound® 2.0
Traction Tire Replacement
Your subway set 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 and remove the
truckside mounting screws as seen
in (figure 12).
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
