I just received my new DCC equipped Bachmann 70 Ton Switcher and out of the box was very noisy, like a roto-tiller running on concrete.
I ran it for several hours for a break-in and the noise decreased slightly. I removed the shell and lubed all the gears and the motor bushings and the unit did get again slightly better. I ran it again for several hours without the shell and the locomotive was as quiet as a KATO unit. Put the shell back on and it was again noisy. Only two screws hold the shell to the chassis.
Read on the Bachmann Forum that some guys added sound proofing to the interior of the locomotive and that helped quiet the locomotive as they claimed the shell acted as an amplifier for the motor and gear noise. I never ran ito a problem like this before and have had noisy locomotives that after some lube and break-in ran quiet.
I know this isn't an expensive locomotive but Walthers Mainline locomotives run much quieter. I know Chet sent his back to Bachmann since it wouldn't run properly and Bachmann claimed that the motor "bearings" needed lubrication. His now runs fine.
Any ideas or suggestions?
Thanks.
