If removing the motor, the black wire needs to be disconnected from the tender. (Cut it inside the tender and resolder it later). The motor and the pickups can be taken off in one piece by unscrewing the 2 motor screws (see motor section) and unscrewing the single cheese head screw shown in the photo. Keep the wheels axles in pairs with the coupling rods in place. The pair at the rear have tyres, the pair at the front don't. The middle axle has a square hole in the wheel for the crank rather than the round hole for the retaining pin, and it has a larger plastic balance weight moulded into the spokes.
