Hyundai Excavator Final Drive Parts

The ZGAQ-02211 Gear Ring and ZGAQ-02224 Carrier Planet are precision-engineered transmission components for Hyundai wheel excavator models R170W-7, R180W-9A, R200W-7, and R210W-9S. These parts are critical elements of the final drive assembly, responsible for delivering stable torque and efficient power transmission under heavy-duty working conditions.

Manufactured with high-strength alloy steel, both the gear ring and carrier planet are heat-treated for durability, ensuring long service life and excellent wear resistance in demanding excavation environments.

   SPARKLING MACHINERY NEW 6Y-8764/559-9478 Gear Pump is a dedicated hydraulic power component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s hydraulic system, it converts mechanical energy into hydraulic pressure by means of gear meshing—delivering a steady flow of hydraulic oil to drive critical working mechanisms (e.g., boom lifting, arm digging, and bucket tilting) during high-intensity operations like construction digging, mining loading, and infrastructure grading. This function is vital for maintaining the machinery’s hydraulic power output, ensuring smooth and responsive operation of moving parts, and preventing hydraulic system lag that could lead to reduced work efficiency or operational delays.

   Engineered to match original equipment performance standards, it maintains reliable pressure and flow stability even under harsh working conditions, including continuous machinery vibration, high hydraulic pressure (up to 25 MPa), and exposure to hydraulic oil contaminants or dust. It resists internal gear wear and oil leakage, avoiding hydraulic system failures that could lead to costly component repairs or unplanned downtime. Backed by strict performance verification, it guarantees consistent hydraulic power supply to support uninterrupted operation of compatible heavy-duty machinery.

   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 L45H L50H VOE17444646 Control Panel is a core operational interface for 2 Volvo excavator models (construction/municipal use). It enables operators to monitor system data (e.g., fuel level, temperature) and control key functions, ensuring intuitive and safe equipment operation. 
   Meeting Volvo OEM standards (VOE17444646), it resists -30°C to 85°C temps, moisture, and vibration, guaranteeing seamless compatibility with L45H/L50H and long-term reliable performance.
