Hand crank kit for Marble Run 003

Upon request, here is my conversion of the Marble Run to manual operation

The conversion is very simple. When the crank is mounted, both manual operation and electrical operation work (crank rotates along)

If you don't want to use a crank for a longer period, the crank can be removed and replaced by the pin with drivers, which makes reassembly quicker

Conversion:

Remove the upper nut…

Remove the tensioning element and slide the tower downwards…..

Hold the gear and remove the pin, then take out the gear….

Install the new gear with the driver pins on the right side and insert and screw in the crank…..

Finally, reinsert the tensioning element and the conversion is complete
