SPARKLING CX300DLC Crawler Excavator ECU

The KHR-series Electronic Control Units (ECUs) are advanced engine and hydraulic control modules specially designed for CASE CX-series crawler excavators, including CX130DLC, CX250DLC, CX300DLC, and CX490DLC. These ECUs—part numbers KHR50000 to KHR50017—manage core operational functions such as engine response, fuel injection, hydraulic system regulation, and machine diagnostics, ensuring smooth operation, fuel efficiency, and maximum productivity on-site. Engineered for OEM-level compatibility and reliability, each unit is: Pre-programmed and ready for installation

   SPARKLING MACHINERY NEW 551-0841+524-5566+6V-5589 Piston Kit is a complete engine core assembly for Caterpillar excavators (heavy-duty construction/mining use). It includes piston, piston ring, and pin, enabling efficient fuel-to-mechanical power conversion. 
   This piston is primarily designed for the C9.3 and C9.3B series engines. It is widely used in high-capacity Caterpillar construction and industrial equipment: 
Excavators: 336, 336GC, 340, 345, 345GC, and 350.
Wheel Loaders: 966 and 972.
Other Applications: It is also used in dozers, industrial oil field engines, and marine engines.

   SPARKLING MACHINERY NEW R210LC9BC R210LC9BH 31Q6-10050 Main Pump is a core hydraulic power component for 2 Hyundai excavator models (heavy-duty construction/mining use). It converts mechanical energy to stable high-pressure hydraulic oil, driving boom, arm, and bucket operations. 
   Meeting Hyundai OEM standards (31Q6-10050), it resists -30°C to 100°C temps, high pressure, and wear, guaranteeing seamless compatibility and long-term reliable hydraulic performance.

   SPARKLING MACHINERY NEW EC460B EC460C EC480D 14541030 Swing Reducer is a premium China-made transmission component specifically engineered for EC460B, EC460C, and EC480D excavators. As a critical part of the swing system, it converts high-speed, low-torque input from the hydraulic motor 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 meshing design for minimal friction, 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.
