Damping GE 70-ton fuel tank noise

[JimJim]

Hello All,

I have a GE 70-ton HO scale locomotive; SP #5114.

When running it makes a HORRIBLE grinding noise. I've removed the fuel tank and shell and it runs silently.

I remounted the shell, not tightening the mounting screws too tight and the noise went away.

Then I remounted the fuel tank and the noise came back, albeit not as loud.

My question is: Is there a way to dampen the motor noise that seems to resonate through the fuel tank?

Thank you in advance for your time and effort.

Lube the motor bearings with a drop of oil on a toothpick and make sure the motor mounts are tight.This motor vibration is transferred through the frame and what ever is touching it.These motors are good ,but like there bearings lubed .Take care doing this not to over lube.I have a few of these with the same issue and tried a little piece of rubber under the motor to cut down the vibration.If this does not work .Try a new motor.
