Fan blades for GY6 125cc engines, compatible with the 139QMA and 139QMB light motorcycle models. Fan accessory.--DTEKGAZ

The GOOFIT Original Fan Wheel for the GY6 125cc engine is a high-precision replacement part specifically designed for the GY6 125cc engine models 139QMA and 139QMB. It precisely matches the dimensions, angles, and mounting points of the original fan wheel and serves to replace worn, broken, or deformed fan wheels. As an essential component of the engine's forced air cooling system, it ensures optimal airflow through the cylinder head and cylinder block, maintaining normal operating temperatures and preventing damage from overheating. As a critical wear part, it contributes to the engine's longevity and performance. Key Features: Precise Original Specifications: Designed specifically for the GY6 125cc engine, it is fully compatible with models 139QMA and 139QMB. The diameter, angle, shaft hole diameter, and mounting method of the fan wheel correspond to the original parts, ensuring that the airflow after installation matches the original engine design. Highly efficient heat dissipation: The fan blades are aerodynamically shaped and generate sufficient and consistent airflow at high engine speeds, efficiently dissipating heat from the radiators. High-quality and durable materials: The fan is injection-molded from high-strength, temperature-resistant engineering plastics (e.g., reinforced nylon). It is resistant to aging and fatigue and will not deform even with prolonged use in the engine compartment, where it is exposed to high temperatures and vibrations. Guaranteed safety: Excellent balancing ensures smooth and quiet operation at high speeds and reduces wear on engine bearings caused by vibrations. Easy replacement: The old fan blades can be directly replaced without having to change the entire fan assembly or clutch cover. This reduces maintenance costs and simplifies handling. Compatibility: Compatible engine platform: GY6 series; Compatible displacement: 125 cc; Compatible engine models: 139QMA, 139QMB (Please check the model designation on the engine block). Primarily affected vehicles: Mopeds, scooters, and some small ATVs equipped with the above-mentioned engines.
