Traction Tire Questions

HEY tn.,

I've  had no problem just undoing the one rod and slipping the tire under the rod . Using two small Phillips drivers to spread the tire around the wheel and you're done.

As far as the jumping engine.........could you post a video ? 🤤

Question1: I have 3 RK steamers and all are like you describe, easy to replace. just changed a y6. One data point for you.

Question 2: Never had this happen. probably need more details, like model, pictures, does it happen in both directions, maybe a video. Seems that could be more than a traction tire.

Good advice from Joe and Hokie on changing tires.

You are going to have to examine your ALCO to see why it leaves the rails.  First, make sure the truck moves freely.  When you lift it up you should be able to rock the truck from side to side and back to front.  If it is tight you will need to open the shell to see if some of the wires are binding.  Next, examine the tire to be sure it is seated correctly.  The tire should be just above the wheel surface.  Look for any difference between the truck that derails and the other truck including the space between the wheels (gauge) which should be uniform.  Finally, with the locomotive on a piece of track, make sure that all four wheels make good contact with the rails.

Good luck and let us know how you make out.

Does the S-1 derail with no cars attached? Definitely need more details to analyze the issue.

What is the arrangement of the tire(s)? Two on one axle, one, one on each axe?  One per axle can cause a truck to turn like an army tank.

Look at the wheel thrust surfaces for something "snaggy" or rough.

Adding an ounce or 7 of weight may fix it too.
