   SPARKLING MACHINERY NEW 416F 420F 422F 428F 430F 343-5643 Air Cleaner is a core engine protection component for Caterpillar 416F/420F/422F/428F/430F excavators (heavy-duty construction/mining use). It filters dust, debris, and contaminants from intake air to ensure clean air supply for the engine, preventing wear and optimizing combustion. 
   Meeting Caterpillar OEM standards (343-5643), it resists -30°C to 85°C temps, clogging, and moisture, ensuring seamless compatibility and long-term reliable air filtration performance.

   SPARKLING MACHINERY NEW WA380 423-03-41310 Radiator is a dedicated cooling component for KOMATSU WA380 wheeled excavators (versatile for construction site material handling, road construction, and mining auxiliary tasks). As the core of the excavator’s cooling system, it efficiently dissipates heat from the engine and hydraulic oil to prevent overheating—ensuring stable performance during high-intensity operations like continuous loading, hauling, or equipment traction.
   Meeting KOMATSU OEM standards (part no. 423-03-41310), it endures -30°C to 110°C temperature fluctuations, resists dust accumulation and corrosion, and maintains consistent heat exchange efficiency. Strict performance testing guarantees seamless compatibility and long-term reliable cooling for KOMATSU WA380.

   SPARKLING MACHINERY NEW EC460B EC460C EC480D 14541030 Swing Reducer is a premium China-made transmission component specifically engineered for EC460B, EC460C, and EC480D excavators. As a critical part of the swing system, it converts high-speed, low-torque input from the hydraulic motor into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.​
   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction, noise, and wear, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
