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 by unscrewing the mounting screws
as noted in Figure 9.
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.
Headlight Replacement Instructions
The PS 3.0 headlights and other associated lights are small LEDs that require a lot less
power and generate a lot less heat than incandescent bulbs, resulting in extremely long
life compared to the incandescent bulbs. The LEDs are not user serviceable.
