Contents of the kit

The Tramfabriek made it easy for you! A lot of pre-work has already done. The nickel silver plates have been soldered together and screw threads have been made in the motor and the plates. You’ll only have to replace the worm and fit the new motor.

Question? Just reach out!



Take apart

Remove screw on top of the model


Remove original motor

Remove two screws on the bottom of  the model (on this picture the new motor has already been installed). Then solder the wires of the new motor to the contact strips and screw the new motor in place.


Place brass adapter in worm

Remove the worm from the original motor (a gear puller, available here, comes in handy). Then press the brass adapter in the original worm. Be careful with the adapter, the wall is only 0.1 mm thick. You might have to clean out the worm to make room for the adapter.


Check fitting

Check how far the worm has to go on the motor axle, glue it on the axle.  When the glue has set,  go immediately test the model in both directions. When the glue hasn’t completely hardened yet, you’ll still be able to make adjustments.


Assemble model

When everything works well, put the parts back together.
