I´ve a Bachmann Shay HO DC that wobbles as if it has “oval flywheels”. Does anybody know something about this? Thanks.
Give Bachmann a call.

David, I live in Argentina, and don´t speak English so well as to make a call…will they answer a mail? Thanks
Mine runs just fine. Try inspecting all the wheels for stuck on bits of crud. Or, you might have an off center wheel, which you could see by putting the shay on the bench, wheel side up, and running it. All wheels ought to be round, if you have one that bounces up and down as it turns, that’s your problem.
Bachmann’s service dept is pretty good. Get in touch and get a return authorization number and they will fix anything.
They should answer mail. Alternatively, I’d sign up with the www.bachmanntrains.com forum, and repost your concern with lkanguage barrier there. Somebody from Bachmann should be able to point you in the right direction faster than snail mail.
While you do that, does it wobble in both directions? or just one way?
As another member stated, run the engine upside down and inspect the wheels as they are turning. You could have a bent axel also. This would cuse the wheels to wobble also, good luck.
