All this banter about oil/grease/etc does not seem to be helping the original poster with his problem.......New trucks are not that pricey, I would consider starting there....maybe new wipers too....
Scott sent me his loco, arrived at 1:30 pm today. In 45 min it was back in the box and on its way back to him. I first pulled the shell and ran with a 9V battery, runs like a clock. Looked at the wheels, very dirty. Cleaned with a little QD followed with Goo-Gone and then 91% alcohol. Ran for some time, no more problems. It would not run at all when it got here. Wheel treads are now clean and bright. All is well. Bob.
I ahte to start a fight with DKS, but here goes. A friend was running trains on his layout one evening. He shut things down and seft the room. His son went down and ran some himself, and on departure did not shut down anything but the overhead lights. He was running a three or four unit lash-up lf Kato SD 40's, which bumped into a stop and ran all night. He discovered this the next morning. About 10 hours of running totally trashed the trucks, and he ordered replacement from Kato. He gave me the old ones to strip for parts. Not only did the wheels rub a circle in the rail completely through the head, it also rubbed deep grooves in the wheels, and the pointed axle tips put holes in the top of the axle cups. That's the equivalent of a day on a ntrak display, no? so maybe just a drop of oil would be good.
Running a loco around the layout, and running it against a hard stop, are two totally different circumstances. The forces and stresses are not even close between the two. Apples and cucumbers.
What I have found is that the wheel threads of certain models seems to attract "dirt" much more agressively than wheel threads of other models.
I too have noticed this and wonder why. To give a specific example: most or all of the metal wheels that have been shipping with the recent Exactrail models I have (e.g. the waffle-side boxes) have become absolutely filthy. As a control sample, I have several cars in the same test train with FVM or BLMA wheels that are still very shiny, even though they have seen nearly identical service on the same track. Does anyone understand the metallurgy at work here? Even the plastic-wheels in this train are pretty clean, so it's not purely an electrostatic/conductivity issue.I plan to replace these wheels, so this is just a matter of idle curiosity.-gfhP.S. Thread drift alert - but it is somewhat topical, as it turns out.
