Most Duplo trains break down due to this faulty gear, which causes the original one to fail and slip, halting train movement altogether. Printing it in PLA and swapping it out with the old one can restore functionality. A helpful video on YouTube demonstrates how to disassemble the train and replace the gear: https://www.youtube.com/playlist?list=PLFumhInDmp_WykUa7-9Z7tjhJpUkuhaLA To secure the new gear, use a socket wrench and hammer to tap it firmly onto the shaft. The design ensures a snug fit, matching the original Duplo part's geometry exactly.
