Just an fyi
I have a MTH r17 mets train and when it would go into a turn it would make a clack clack ckack sound. It was driving me nuts. I swapped motot, truck, Greased everything to no avail. I kept on trying to find out what it was. Process of elimination led me to the collection roller on the front truck. Changed it out and no noise. Next time I will look at the rollers first. Has anyone ever had this problem. Just curious and also want to share this experience. Feel free to move to the propper forum.
Thanks
