The Flywheel PTO (KFP.SAE1) positioned between the engine and main transmission provides high torque independent of the speed of the auxiliary equipment in heavy-duty vehicles with superstructure. The PTO is compatible with SAE1 engine connection. It is driven by the engine flywheel and works independent of the vehicle clutch. The system is oil-cooled and the drive from the engine is transmitted to the PTO on the top axis, thereby activating the equipment connected on the output. The system consists of a single PTO output.The overall system provides uninterrupted motion transmission from the engine through the main transmission clutch pack. The PTO on the top can be engaged/disengaged through hydraulic control.
