As a anniversary present very many years ago my wife bought me this lovely 0-6-2 Zillertal locomotive but in one of the house moves the crank and motion gear got broken.
Many attempts to repair them has ended in failure. LGB were at that time making engine blocks for Playmobil and they are almost the same dimensions so in desperation I changed the motorblock to the Playmobil one with a new motor and the Playmobil Cylinder block and linkage. Not nearly so ellegant but very reliable. eBay provides a superb source of Playmobil spares under the vendor PLAYMOKING. I have bought many items from this gentleman and is highly recommended.
