One would hope that QC reports make it back to the factory and someone pays a bit more attention to the material and molding on these vital parts.
If these were uncommon failures, I wouldn’t mind buying a truck or two to rob parts off of. But I’m already looking at needing to buy six locos to get the four I need. That’s after a good luck pair to start and hoping that the next two are keepers – and not like the pair I’m working through right now that are essentially just one sorta working loco at the moment. That’s going to be a whole lotta trucks.[^o)]
