Smoother running at low speeds*, lower maximum speed and quieter.

Check if you have the same model, when in doubt (see below)..

Take apart

1

Remove the tender from the locomotive with the three small screws for the connecting bar and wires.

2

Desolder the wires and remove the electronic components. In this example I had in my hands, the DCC socket was removed from the model, so don’t let that confuse you.

3

With the wires removed, you can lift the motor out. Remove the yoke from the motor shaft. You will need this again. 

4

Cut some of the tape to the size that it fits between the wheels, and put it there. The tape is 0.75 mm thick.

5

Red wire on this side, to the right track.

If the brass adapter is not glued on yet, glue it on with Loctite metal glue (not superglue, as you don’t have enough time to position it in place), or similar from other brands. Align the edge of the brass adapter with the front of the motor shaft.


After drying, fit the black yoke (as I’ve been told the black thingie is called.

Blue wire on this side, to the left track.

As my model didn’t have the DCC socket, I just connected the wires to the wheel contact wires. With the DCC socket available, solder the red motor wire to the orange decoder wire (motor +), the blue to the grey decoder wire (motor -).

6

Put the tender on the track and test if the motor starts spinning when power is applied to the track. If you run DCC, test it with DCC.

7

If all works well, fit the tender housing back on and connect the tender to the locomotive. It should all run much better now.

Digital

You can use decoders with the coreless motor. Train-O-Matic does an excellent micro decoder, available here from the Tramfabriek.


For optimal performance, you need to change some CV settings on a decoder. For several decoder brands, the ideal CV settings can be found by clicking here.
