SPARKLING CASE CX490DLC ECU – Reliable Excavator Control Unit

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 K3551.178-6190 Radiator is a dedicated thermal management component for Liebherr excavators (widely used in construction, mining, and heavy infrastructure projects). As the "engine cooling core", it dissipates excess heat from the excavator’s engine and hydraulic system—preventing overheating during high-intensity tasks like continuous digging, rock breaking, and heavy lifting, while ensuring stable equipment operation even in high-temperature environments.
   Meeting Liebherr OEM standards (part no. K3551.178-6190), it maintains efficient heat dissipation (heat rejection rate ≥85%), endures -30°C to 120°C temperatures, resists corrosion and vibration, and ensures leak-free coolant circulation. Strict testing guarantees seamless compatibility with applicable Liebherr models and long-term thermal system reliability.

   SPARKLING MACHINERY NEW R200W7 ZGAQ-01270 Gear-Ring is a dedicated transmission system component for Hyundai R200W7 wheeled excavators (widely used in construction, municipal engineering, and road maintenance). As a core part of the excavator’s power transmission mechanism, it meshes with gears to transfer torque between the engine and driving system—ensuring smooth power delivery during tasks like digging, loading, and on-site mobility, while maintaining stable operation under heavy loads.
   Meeting Hyundai OEM standards (part no. ZGAQ-01270), it endures -30°C to 85°C temperatures, resists wear and vibration, and maintains precise tooth meshing accuracy. Strict testing guarantees seamless compatibility with Hyundai R200W7 and long-term transmission system reliability.

   SPARKLING MACHINERY NEW 440-00257 Cylinder;Arm is a dedicated hydraulic actuation component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s arm movement system, it converts hydraulic pressure into linear force to drive the arm’s lifting, lowering, and extending actions—supporting critical on-site tasks like digging, material grabbing, and precision placement in construction, mining, or infrastructure projects. This function is essential for maintaining the machinery’s operational flexibility and load-bearing capacity, directly ensuring smooth coordination between the arm and bucket, and preventing movement lag or jams that could reduce work efficiency or cause safety hazards.

   Engineered to match original equipment performance standards, it maintains stable pressure retention and smooth piston movement even under harsh working conditions, including heavy load stress (up to rated 500 kN), continuous vibration, and exposure to dust or hydraulic oil contaminants. It resists internal leakage and cylinder wall wear, avoiding hydraulic system inefficiencies that lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable arm actuation to support uninterrupted operation of compatible heavy-duty machinery.
