Using these HO Scale Kadee/Vulcan trucks is easy. First, use a #2 or 2 - 56 screw to mount the trucks. When it comes to the journal box, if you need to replace it, just remove the pin. For normal use, enjoy the smooth tracking and free - rolling features. As for maintenance, keep the wheels clean to ensure they roll freely. Check the springs regularly to make sure they are flexible. Avoid exposing the trucks to strong magnetic fields as the wheels are non - magnetic. Also, store them in a dry place to prevent any metal parts from rusting. If you notice any parts getting loose, make sure to tighten them up in time.
