SPARKLING MACHINERY CAT Parts – Quality Excavator Components

The 558-5127 / 5585127 Valve GP-QDR is a genuine replacement hydraulic control valve designed for CAT D7 Track-Type Tractors. Manufactured to Caterpillar OEM standards and weighing 27KG, this original valve ensures high precision fluid control in demanding construction and earthmoving environments.

As a critical component in the hydraulic control system, the GP-QDR valve regulates the flow and pressure to various functions of the bulldozer, helping to deliver reliable and responsive operational performance. SPARKLING MACHINERY offers this valve as part of our premium product lineup—ideal for equipment owners seeking both authenticity and performance assurance.

   SPARKLING MACHINERY NEW ZX350LC-5B ZX350LCN-5B 8970241240 8943925532 Gasket is a dedicated sealing component exclusively designed for ZX350LC-5B and ZX350LCN-5B excavators. As a core part of the excavators’ engine, hydraulic, or fuel systems, it creates a tight, leakproof barrier between mating components (e.g., engine cylinder heads, hydraulic valve covers, or fuel system housings). This function is critical for preventing fluid (oil, coolant, fuel) or gas leakage during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance—directly protecting internal components from contamination, maintaining system pressure stability, and avoiding unplanned downtime caused by leakage-related failures.

   Engineered to match original equipment performance standards, it maintains strong sealing performance even under harsh working conditions, including extreme temperatures (-20°C to 180°C), continuous excavator vibration, and exposure to oil or coolant additives. It resists deformation and material degradation, avoiding seal failure that could lead to costly component damage or environmental pollution. Backed by strict performance verification, it guarantees reliable sealing to support uninterrupted operation of ZX350LC-5B/ZX350LCN-5B excavators.

   SPARKLING MACHINERY NEW 119266-21700 Crankshaft is a premium China-made engine core component designed for compatible construction machinery (such as excavators, loaders, and generators) and industrial engines. As the "power transmission backbone" of the engine, it converts the reciprocating motion of pistons into rotational motion to drive the machinery’s hydraulic system, undercarriage, and other key components. This critical function ensures the engine delivers consistent torque and power for heavy-duty operations—including digging, lifting, and continuous power generation—in construction, mining, and industrial scenarios.

   Engineered to original equipment standards, it maintains exceptional structural stability even under high rotational speeds (up to industry-standard RPM thresholds) and extreme load conditions, as well as harsh working environments like vibration, temperature fluctuations, and dust. With precision-machined journals and balanced design, it minimizes friction between moving parts and reduces engine vibration. Backed by strict quality verification, it guarantees reliable power transmission to support uninterrupted machinery operation and extend overall engine service life.

   SPARKLING MACHINERY NEW HW140 R140W7 R140W7A R140W9 R140W9A XJDD-00233 Piston Assy is a dedicated engine core component for HYUNDAI HW140, R140W7, R140W7A, R140W9, and R140W9A wheeled excavators (versatile for road construction, municipal engineering, and material handling). As a key part of the engine’s combustion system, it converts fuel energy into mechanical power to drive the excavator’s movement and hydraulic functions, ensuring stable performance during tasks like loading, digging, and road grading.
   Meeting HYUNDAI OEM standards (part no. XJDD-00233), it endures high temperatures (up to 300°C) and pressure, resists wear and combustion byproducts, and maintains tight sealing with the cylinder. Strict testing guarantees seamless compatibility and long-term reliable operation for the five HYUNDAI models.
