To disassemble the TM Racing 125 engine, you must first remove the engine block from its housing located in the center of the frame: to ensure the removal takes place, it will also be necessary to disconnect the exhaust pipes and all the cables from the appropriate sensors. You can then proceed by loosening the screws that secure the cylinder to the top of the engine block in order to remove it: after removal, you will be able to locate the piston, which must be detached from the connecting rod. You will then have access to the crankshaft and all the components that need to be replaced.
