Premier GP-30 Diesel Engine Operating Instructions
Light Replacement Instructions
The locomotive’s lighting is controlled by a constant voltage circuit in the
engine. The lights are easy to replace when they burn out. The bulb has a
quick disconnect plug that attaches the bulb harness to a light circuit.
Replacement bulbs are available directly from the M.T.H. Parts Department.
Follow the body removal instructions found in the Lubrication and Greasing
Instructions.
Gently disconnect the bulb harness from the socket on the constant voltage
circuit and replace the bulb.
B. 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. See Fig. 8 for which
screws you must remove to do this.
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.
