On30 Shay

[seacoast]

I recently purchased a Bachmann On30 Shay. It is quirkly yet an unique locomotive and speed isn't its gig thats for sure. One issue that I seem to have with it , it wobbles back and forth alone or pulling "a" car. Any suggestions to this? It seems as though Bachmann should have used metal gears for this loco as the plastic is not tough enough. Suggestions?

I had a similar problem with 3 different shays. I posted this problem twice on this meaasge booard. I finally talked to a service technician at Bachmann and he informed me that my problem was not isolated. Apparently a bad batch of gears on some shay's trucks. He sent me a replacement pair of trucks, and now the shay runs fine. I believe that someone suggested that a gear might be cracked and sure enough one of the gears on a truck that was replaced had a large crack in it.

Ok,if it continues as you stated I will contact bachmann tech.
they should have put metal gears in them , poor design flaw.
