SPARKLING 4472.377.047 Excavator Part – Durable, Precise, Reliable

The 4472-377-047 Carrier Disc is a critical transmission component designed for the HYUNDAI R170W-7 Wheel Excavator. As part of the planetary gear assembly, the carrier disc ensures smooth torque transfer and balanced load distribution within the drive system, supporting reliable movement and effective excavation operations.

Manufactured with high-strength materials and strict quality control, this carrier disc (also referenced as 4472377047 or 4472.377.047) offers precise fitment and extended durability, making it a cost-effective and dependable replacement for OEM parts.

   SPARKLING MACHINERY NEW R250LC7 R250LC7A 31EN-10071 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R250LC7 and R250LC7A excavators. As a critical part of the swing system, it reduces engine speed to generate high torque, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during positioning, material handling, and precision operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under heavy rotational loads and continuous use. With optimized gear meshing design for minimal 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.

   SPARKLING MACHINERY NEW 420E 420F 428F 430E 430F 432F 348-9769 Valve GP-P R is a dedicated hydraulic pressure reducing valve group for Caterpillar 420E, 420F, 428F, 430E, 430F, and 432F backhoe loaders/excavators (widely used in construction, municipal engineering, and medium-to-heavy material handling). As a core pressure control component of the equipment’s hydraulic system, it reduces high-pressure oil from the main system to a stable, safe level for sensitive sub-systems (e.g., hydraulic steering, auxiliary controls)—ensuring smooth, damage-free operation during tasks like heavy digging, loading, and backhoe maneuvering.
   Meeting Caterpillar OEM standards (part no. 348-9769), it endures 28 MPa inlet pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains consistent pressure reduction performance. Strict testing guarantees seamless compatibility with the six Caterpillar models and long-term protection for hydraulic sub-systems.

   SPARKLING MACHINERY NEW EC330B EC360B VOE14612629 Cable Harness is a premium China-made electrical connection component specifically engineered for EC330B and EC360B excavators. As a critical part of the machinery’s electrical system, it organizes and transmits electrical signals between key components—such as sensors, controllers, and actuators—ensuring seamless communication for functions like engine control, hydraulic system operation, and cabin electronics.

   Designed to original equipment standards, it maintains stable signal transmission even under harsh working conditions, including vibration, temperature fluctuations, and exposure to dust or moisture. With optimized wire routing and secure connector design, it prevents signal interference and reduces the risk of electrical failures. Backed by strict quality verification, it guarantees reliable performance to support uninterrupted machinery operation, minimizing downtime caused by electrical issues.
