Dear Joe:
       I didn't see anything at that site reference regarding the smoke unit.
Thanks,    Jerry

I ordered and installed the Bachmann recommended smoke unit. It was different than the original and did smoke a little. It is the worst smoke unit I have ever seen. If puffs very little smoke. A waste of $25!

I have a Williams Berkshire 2-8-4 stock #BERK116. The smoke unit is not working. It says  it has a seuthe smoke unit. Where can I get a replacement?

Thank you for your help. I already tried the NWSL site and they were unable to help. I'll order the assembly and hope it holds up. Thanks again for your help.

The loco is a 2-6-0 spectrum. I thought I had a bad axle gear so I followed your article and ordered a replacement gear. When I opened the gearbox the center double gear was stripped. Bachmann says they don't sell the individual gears. You have to purchase the complete motor/gearbox assembly. That's ok, but did they improve the gears or are they just going to fail again.

How can you get Bachmann gearbox gears without buying the complete motor/gearbox assembly?
