This installation is for N Scale Kato RS 2 uses TCS K2D4 Decoder and was performed by A.G. and N.G.

This installation requires special procedures so be sure to follow each step!

The upper picture shows the Kato RS2 with its shell on.

This picture shows the locomotive's chassis with its shell taken off and the original lighting board. Be careful as you take off the shell because it is difficult to remove and can be broken.

Now that the original lighting board has been removed you are ready to use Kapton Tape to isolate the motor tabs and frame. The above picture clearly shows that you should place a section of tape over the frame directly above the motor tabs as well a covering the rear chassis.

Next carefully spread the copper tabs so that they fit over the chassis as shown in the picture above.

Carefully slide the decoder down while making sure that the copper tabs remain aligned as show in the picture above. Stop lowering the decoder when it comes in contact with the frame.

Now, WITHOUT BENDING THE DECODER, slide it gently to the left until the rear frame pickup tabs line up with the notch in the chassis.

With the tabs properly aligned over the notches, carefully press the decoder down (maintain evenly distributed pressure to avoid flexing the board). Use extra care not to break or twist the copper motor tabs. Now you are ready to slide the decoder towards the rear of the locomotive and lock it into the notches in the frame.

At this point you will note that the copper motor tabs are not properly tucked behind the copper decoder tabs. Being very GENTLE use tweezers to slide the motor tabs from the locomotive to the left, and then behind the copper decoder tabs. Your installation should now look like the picture below.

This is a picture of the fully installed board. All in all it is not a very difficult installation. If you, for any reason, need to remove the K2D4, it will have a tendency to get hung up on the front LED, so you will have to lift this LED over the hump in the locomotive frame.

Make sure you add value of one to CV29 so that the engine runs in the right direction.
