loco remotored problem

[Anonymous]

i have 2 athearn tunnel motors both been repowered with mashimma motors with the original flywheels . they run smooth at low speeds but when i wind up the speed and when they go around corners they make a lot of noise and the person who remotered them for me says that the flywheels are balanced propelery so my question is , where abouts would this extremly loud noise be comming from and what should i do to fix the problem?? thanks

Try running them without the bodies if possible. If the noise persists, look at the gears and UJ's for possible binds, the UJ's can be tricky to re-align without binds on sharp curves and at speed. If the noise gets a lot less with the bodies off, it's most likely there all the time but the bodies are allowing the noise to resonate,and accentuate the sound,
Good luck,
