Hey guys I need some info. I have two Atlas/ roco locos. Both sound like meat grinders when running. they run good just loud and have a heavy vibration to them. I have took the trucks apart and cleaned and oiled them. I just don't know what else to check. these are the old Yellow box Atlas units. Any info on where to check to fix this would be a great help.
 
Check the motor mounts, and check to make sure the flywheels aren't off-center or loose. They are not the absolute wuietest engines out there, though much better than the old Athearn engines of yore.
 
You know I wonder about the flywheels. Now on the motor mounts How tight should the screws be. these are not falling out but they are no where near tight.
