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, they may
occasionally need replacement.
First, remove the truck sides from the truck block. To do this, turn your engine
upside down and remove the chassis as detailed on page 12.
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. 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 will not seat inside the groove properly.
5. Reassemble in the reverse order.
