Hi all
As a new member of this forum I have come requesting some thoughts on a matter.
I have purchased two H0e steam locos off Ebay (see attached photo) and they both run well. However each has a noticeable wobble when they are running.
I first saw this wobble on a diesel chassis from Roco that I remotored and used to make a diesel shunter with a 3D printed body. These two steam chassis are Atlas and I believe Atlas and Roco are, if not one and the same, closely linked.
On the diesel I have tried adjusting the engagement of the worm with the main drive gear with no joy at present.
I intend remotoring the Atlas chassis and would like to be sure I can resolve the wobble before embarking on that exercise.
I would welcome any suggestions as to what is the problem and how it can be resolved. For my part I am suspecting it has something to do with the coarseness of the gearing or play in the gears and this may not be so easy to resolve unless one of you knows otherwise.
The old ATLAS chassis used in these Roco locos up to about 1980 are not the best. They tend to ware out with use. The wobble is down to one or more of the wheels being moulded off center. This is very common on these chassis.
The only way to fix this is swapping them about to get all good ones on one loco!

Thanks for this advice so it's a process of elimination to find the wobbly wheel.

Yes.
