Note: I did indeed try to fit a (7 x 5 mm flywheel, but it didn’t have any effect, so don’t waste your time on considering that! ;-)
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.
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.
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 and solder wires to the motor. Check the position of the worm and glue it with Loctite or Superglue on the shaft. Though if you feel it has a tight fit, glue is not needed. The tape was there to protect the contact when I was trying to fit it with a flywheel, but without that, there is enough breathing space for the contact, so that shouldn’t be needed.
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).
And one more model has been brought back to the future!
