12 RailKing R-12 Subway Set
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 10.
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 (order online: www.mth-railking.com,
