I was looking for a solution to a problem and discovered this forum. I hope someone can help me solve a problem. I am modeling the Canandaigua NY yard in HO. My Spectrum Doodlebug is noisy. Does anyone know how to easily remove the body from the doodlebug so I can silence its noisy gearing and motor. It is the only Spectrum I have that 'growls' as it runs. I've had it apart before to add DCC to it but it is difficult to take apart and I have already broken one detail doing so. The noise is driving me nuts.
