RailKing F-3 Diesel Engine
To clean the track, use a clean rag and denatured (not rubbing) alcohol. Unplug
the transformer and wipe the rails of the track, turning the rag frequently to
ensure that you are using clean cloth on the rails. Because the manufacturing
process leaves a coat on RealTrax, you should clean the rails after the first 30
minutes of use (you may smell something burning during initial use as the coat
burns off; this is normal). Thereafter, keep an eye on the track and clean it when
it gets dirty to ensure good electrical contact and to lengthen the life of the tires.
Traction Tire Replacement Instructions
Your locomotive is equipped with two neoprene rubber traction tires on the rear
set of flanged drivers. While these tires are extremely durable, you may need to
replace them at some point.
1. Remove the truck sides from the truck block in order to slip the new tire over
the grooved drive wheel. To do this, remove the screws as shown in Fig. 7.
2. 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.
3. 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.
4. 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.
5. 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.
6. Reassemble the truck sides to the
truck blocks.
Replacement Tires are available
directly from the M.T.H. Parts
Department.
