Contents of the kit

Check the new motor housing for accurate fitting and to get familiar with the fitting.

Question? Just reach out!

Lubricate the gears, then push everything (straight!) in place. If you have to take everything apart again, twist a small screwdriver between the underside of the roof and the top of the motor housing.

B. Cut wires to size. Solder motor wires to contacts below motor, (the contacts that are pointing upwards). If you would solder the wires to the side of the motor it will either not close, or you will create a short.

A. Put some insulating tape only under the front side of the motor, so it is insulated from the contacts below.

Important: to make sure your trains all move in the same direction, connect the red and blue opposite of how I did it!

Now you have see through, or there is enough space to fit a small decoder on one of the sides.

And one more model has been brought back to the future!
