@Ukaflyer posted:If it was mine I would gently bend the two tabs up at the end of the motor and pull the end plate off with the brushes. Then I would clean and polish the commutator and gently clean the ends of the carbon brushes and put back together again and see if it runs, you have nothing to lose as it isn’t running anyway.
Do not take the can motor apart. As stated above, its a DC can motor. It will not run directly from the transformer. There is circuitry in the accessory which is converting the AC to DC so the motor will run. Test the motor with a 9 volt battery or 1.5 volt battery. Not sure the voltage requirements of the motor. Then you can check if the gears are meshing correctly. I have this accessory on my layout. It has worked flawlessly for many, many years. If the can motor is dead, then you just need a replacement can motor.
