SPARKLING HD512 Sprocket Replacement – Durable Excavator Part

SPARKLING MACHINERY offers a premium Final Drive Assembly (619-62500001) paired with a high-strength Sprocket (317-50201000) for the Kato HD512-III excavator. This drive system is engineered for maximum torque, reliable track propulsion, and exceptional durability under rugged working conditions.

The Final Drive Assy transmits hydraulic power to the tracks with precision and is built using high-grade gears, seals, and housings. The Sprocket, heat-treated for wear resistance, guarantees smooth engagement with the track links and long service life even in abrasive environments.

   SPARKLING MACHINERY NEW 31Q9-10030 Main Pump is a core hydraulic power component exclusively for Hyundai R330LC-9S excavators (heavy-duty construction/mining use). It converts mechanical energy to stable high-pressure hydraulic oil, driving boom, arm, and bucket operations for heavy-load tasks. 
   Meeting Hyundai OEM standards (31Q9-10030), it resists -30°C to 100°C temps, high pressure, and wear, guaranteeing seamless compatibility and long-term reliable hydraulic performance.

   SPARKLING MACHINERY NEW A25D EC140C EC240C EW40D 960254 O-Ring is a dedicated sealing component exclusively engineered for VOLVO A25D articulated dump trucks, EC140C/EC240C excavators, and EW40D wheeled excavators—key equipment in construction, mining, and municipal infrastructure projects. As a critical part of the machinery’s hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hoses). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like heavy hauling, digging, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous machinery vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for VOLVO A25D/EC140C/EC240C/EW40D systems. Backed by strict performance verification, it guarantees consistent sealing support for these VOLVO models.

   SPARKLING MACHINERY NEW 31M9-02130 Fuel Cap is a core fuel system component for Hyundai excavators (construction/mining use). It provides reliable sealing for the fuel tank to prevent fuel leakage, dust/water contamination, and fuel evaporation. 
   Meeting Hyundai OEM standards (Part No.: 31M9-02130), it features excellent wear resistance and corrosion resistance, ensuring seamless compatibility with original equipment and long-term stable protection of the fuel system.
