Good Morning All,
I have several Williams/Bachmann semi-scale GG1’s, and for some reason the shells seem to all wobble (like a bobblehead) to some degree as if there is a loose screw somewhere between the shell and the frame. I have checked the screws that hold the shell to the frame and they are not loose. Does anyone have this same problem and can recommend a fix? Do the shells on the Lionel GG1’s have this same problem?
Thanks,
Bernard
The same is true for my W/B EP5, the frame wobbles on the trucks, but I think that it may be a design “feature” to assist the loco in negotiating O31 curves and/or rough track.
Its normal for the shell and frame to wobble on the trucks but if the frame moves relative to the shell then you need to check for pinched wires between the shell and the frame. With eight screws holding the two together, there shouldn’t be any movement.

I have a few Williams engines (including the semi-scale GG-1’s, although they are all pre-Bachmann production) and have not noticed any problems with wobbling - the GG-1 is a tall engine and if your trackwork is uneven that could cause it to wobble. You might want to put a small level on a flat car and push it slowly along the track where the wobbling occurs. If you have tubular track, the wobbling could be caused by overtightened screws.
Good luck!

I have some larger Williams(pre-Bachman) engines, SD-45’s and have not noticed any wobbling, even my GP-9’s, a.k.a. jack-rabbits, run smooth!
Have you checked the area where the truck meets the frame? Maybe it is a design flaw that you will have to live with.

Thanks for the info. I think it is a design flaw on this particuliar engine. Not a big deal, unless the engine is moving faster.

Thank you one and all for your responses!!
Sorry if this seems obvious but did you check the flat head philps screws under each truck for tightness? One is under the pick up roller assembly.
