Hello, I purchased the Kato N scale 106-085 UP water tender set.
I was having a problem with one of the tenders uncoupling periodically. I noticed that the coupler centering spring was off the post. I popped the coupler off and realized the spring was badly kinked up and not salvageable. I popped the coupler back on with no centering spring and it actually works fine now and does not uncouple by itself.
Are these springs there for centering simply to make the coupling process a little easier? Is this spring only really needed when using magnetic coupling?
Also, does anyone know what part number coupler this is? They are not truck mounted. They just snap off and on but have not seen any like them. Was thinking about picking up a couple spares.
Thanks
Brad.
