The 168F Flywheel Cooling Fan is a core heat dissipation component for 168F small engines (generators, power tools). Made of high-temperature-resistant plastic, it is mounted on the engine flywheel and rotates with it.Its key function is to generate directed airflow: as the flywheel spins, the fan blades push air toward high-heat components (cylinder, valve mechanism), accelerating heat dissipation and preventing engine overheating. The curved blade design optimizes airflow volume while reducing noise during operation.Designed to match 168F flywheel specifications, it replaces damaged/worn fans (which reduce cooling efficiency, causing overheating). Installation requires aligning with the flywheel’s mounting points and securing with fasteners. The durable plastic construction resists deformation at high temperatures, suitable for long-term high-load use.
