Question? Just reach out!


It’s not a very easy model to open. The hooks might be brittle, because of the age of the model. There are four (red) hooks on the housing, which are held by tabs on the black frame.

As you see, not everything worked out for me. I got annoyed. Oh well, it fitted perfectly afterwards.



This is what we are dealing with.

De-solder the red wire to the motor from the board.

Watch the



Press the brass tubes in the two discs that came with the kit, if this isn’t already the case. A push with a flat screwdriver should be enough, otherwise with a small hammer.

If it is really too tight, you might want to clean the worm with a long, round diamond file. This one comes from Hobbycraft (UK), but you can find them on eBay as well.


Remove the two clips that hold the motor in place.


Take the motor out and remove the worm. Tips on how to do that, you will find in this article. or see the video (left).

Hammer the brass adapter, supplied with the kit, in the Minitrix worm. Make sure you put it in the narrow side of the worm, otherwise it doesn’t stick.


Cut contact strip. Leave enough so you can solder the (minus) wire of the motor to it.


Fit the flywheel, one disc with brass tube inside, and the worm to the motor. Note that the insert in the flywheel has to face the motor, to come as close as possible to the motor. 

Check the position of the worm with the gear in the chassis and glue it with Loctite on the shaft. Though if you feel it has a tight fit, glue is not needed. 

Customer’s HOT TIP: instead of using the wires, connect a hard wire to the contacts, like the ones from a diode, resistor etc, or hard copper wire. This will keep the motor from spinning without the need of the tape on the bottom of the motor.


This is how the hole thing comes together. Remove the tape cover under the motor and place the motor with the tape downwards on the chassis. Look at the picture for the correct position. Make sure the worm is centred above the gear. If you have glued the worm, with the Gear puller you will still be able to move it.

Red arrows: Fit the discs on each shaft, then place them where the clips go.


Test it and when it’s all running perfectly, place the housing again. If you want to convert it to DCC, the sweet settings for several brands of decoders are explained on this page (click link).
