When I put one of my Heislers on the track just now the front truck came off! Looks like there are 4 tiny screws that mount the truck to the underside of the chassis that worked their way out of which I found 3. Would Bachmann parts have these tiny screws?
It appears there is a large center screw that the mount with the 4 tiny screws hold on to. I don’t see how I can get in there to screw the mount back on to the chassis. I’ve included some pictures hopefully that show this issue.
