Hyundai R520LC-9 Hydraulic Parts

The 31QB-10037 / 31QB-10030 Hydraulic Main Pump Assembly is an essential component for delivering stable hydraulic power to your Hyundai crawler excavators. Built for high-performance, this pump guarantees powerful flow, high efficiency, and exceptional durability even under extreme excavation workloads.

🔧 Key Features:

• Original quality fitment for Hyundai’s large crawler excavators

• Ensures precise pressure regulation and smooth hydraulic operation

• Manufactured with high-grade wear-resistant components

• Rigorously tested for flow rate, pressure endurance, and temperature resilience

   SPARKLING MACHINERY NEW 11221161 Cylinder Head is a core engine component for Volvo excavators (heavy-duty construction/mining use). It seals the engine cylinder top, houses valves, and ensures efficient combustion by maintaining compression. 
   Meeting Volvo OEM standards (11221161), it resists up to 300°C high temps, pressure, and corrosion, ensuring seamless compatibility and long-term reliable engine performance.

   SPARKLING MACHINERY NEW 0445020265 Fuel Pump is a premium China-made fuel supply component designed for compatible construction machinery (such as excavators, loaders) and heavy-duty diesel engines. As the "fuel delivery backbone" of the engine system, it precisely controls the pressure and flow rate of diesel fuel, delivering it from the fuel tank to the engine’s injection system. This ensures consistent, atomized fuel supply—critical for optimizing combustion efficiency, reducing exhaust emissions, and maintaining stable engine power output during heavy-duty operations like digging, lifting, and continuous idling in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains reliable performance even under harsh working conditions, including extreme temperatures (-30°C to 80°C), high vibration, and exposure to contaminated fuel or dust. With an optimized internal rotor design and high-seal integrity, it minimizes fuel leakage and resists wear from particulate matter. Backed by strict quality verification, it guarantees uninterrupted fuel delivery to support consistent engine operation and extend the service life of injection system components.

   SPARKLING MACHINERY NEW EC200D EC210 EC210B EC210C EC210D 14518516 Relief Valve is a dedicated hydraulic safety component for VOLVO EC200D, EC210, EC210B, EC210C, and EC210D crawler excavators (mid-to-heavy-duty equipment for construction, municipal engineering, and light mining). As the core safety guard of the excavator’s hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during trench digging, material loading, and small-scale rock breaking.

   Meeting VOLVO OEM standards (part no. 14518516), it endures 32 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict performance testing guaranteeing seamless compatibility and safe operation.
