I have the WM 3 truck shay, Lionel 6-84239. Ever since I have had it, I noticed that the rear tender moves up and down as it moves along the track, yet the frame that the truck is attached to stays straight.
Even if sitting on the tracks, the tender tends to lead toward the back. When sitting on the tracks, I can move the tender shell up and down (front to back) with my fingers very easily. There is a lot of up and down play of the tender shell.
I am wondering if others have had the same issue. Is there a fix for this to hold the shell tight to the frame? I have turned the tender upside down and all the screws appear to be tight.
Thanks,
RAY
