   SPARKLING MACHINERY NEW B55W-2 DX53W DX55W DX60R 1.519-00002 Coil; Solenoid is a dedicated electrical control component for Doosan B55W-2, DX53W, DX55W, and DX60R wheeled excavators (versatile for municipal engineering, landscaping, and small-scale construction). As a key part of the excavator’s hydraulic or fuel system, it converts electrical signals into electromagnetic force to control valve actuation, ensuring precise operation of functions like bucket tilting, arm movement, and engine fuel supply during delicate tasks.
   Meeting Doosan OEM standards (part no. 1.519-00002), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains stable switching performance. Strict testing guarantees seamless compatibility and long-term reliable operation for the four Doosan models.

   SPARKLING MACHINERY NEW HX330L 39K9-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for HX330L excavators. As a critical part of the swing system, it converts high-speed, low-torque input 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 design for minimal friction and noise, 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 R170W7 R170W7A R170W9S ZGAQ-02283 Cylinder-Steering is a premium China-made hydraulic component specifically engineered for R170W7, R170W7A, and R170W9S wheel excavators. As a critical part of the steering system, it converts hydraulic pressure into linear motion to enable smooth and precise directional control, ensuring stable maneuvering during operation, positioning, and job site navigation.

   Designed to original equipment standards, it maintains consistent force output and responsive operation even under heavy loads and continuous use. With optimized seal design for leak resistance and robust structural integrity, it adapts seamlessly to harsh working environments, from muddy construction sites to rough terrain. Backed by strict quality verification, it guarantees reliable performance to support safe and uninterrupted machinery operation.
