To dismantle the Derbi D50B1 engine, first remove it from its housing by loosening all the screws that secure it to the respective mounts and disconnecting the pipes and connectors. Once the block is removed, proceed to unscrew the bolts that secure the cylinder, completely removing it and locating the piston underneath: the piston must be detached from the connecting rod by widening the retaining ring and thus separating it from the connecting rod. This will allow you to split the two crankcase halves at the bottom, enabling you to replace the necessary components.
