Built to OEM standards (e.g., part no. LNM0639 / 201-26‑00130), this gearbox features hardened steel gears and robust bearings—ensuring durable operation under heavy load. It’s designed for easy drop-in replacement and reduces maintenance downtime. Ideal for construction, demolition, and excavation applications.

The SANY 14532878 Harness Assembly (HARNESS ASSY) is a high-quality electrical wiring component designed for SANY excavators, including models SY330H and SY305HC9I3KH.5.4B.

This harness assembly plays a critical role in the machine’s electrical system by securely transmitting signals and power between key components such as sensors, controllers, engine modules, and onboard displays. Designed to withstand the harsh environments of heavy-duty construction operations, it features durable insulation, corrosion-resistant terminals, and OEM-standard connectors for easy installation and long service life.

Whether you are conducting routine maintenance or replacing damaged wiring, this 14532878 wiring harness ensures optimal machine communication and electrical performance. It helps reduce downtime, prevent faults, and support efficient operation on the jobsite.

   SPARKLING MACHINERY NEW 420F 428F 430F 432F 434F 444F 396-4890 Valve GP-P R is a dedicated hydraulic pressure reducing valve group for Caterpillar 420F, 428F, 430F, 432F, 434F, and 444F backhoe loaders/excavators (widely used in construction, municipal engineering, and heavy material handling). As a core pressure control component of the equipment’s hydraulic system, it reduces high-pressure oil to a stable, safe level for sensitive sub-systems (e.g., hydraulic steering, auxiliary functions)—ensuring smooth, damage-free operation during tasks like heavy digging, loading, and backhoe maneuvering.
   Meeting Caterpillar OEM standards (part no. 396-4890), it endures 30 MPa inlet pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains consistent pressure reduction performance. Strict testing guarantees seamless compatibility with the six Caterpillar models and long-term hydraulic sub-system protection.

   SPARKLING MACHINERY NEW 240DLC 250GLC 270DLC 290GLC DZ100217 Injector is a dedicated fuel injection component exclusively designed for 240DLC, 250GLC, 270DLC, and 290GLC excavators. As a core part of the excavators’ engine fuel system, it precisely atomizes and sprays fuel into the combustion chamber—ensuring optimal fuel-air mixing for efficient combustion during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance. This function is critical for maintaining stable engine power output, improving fuel efficiency, and reducing exhaust emissions, directly preventing issues like incomplete combustion (which causes carbon buildup) or fuel waste that impacts operational costs and environmental compliance.

   Engineered to match original equipment performance standards, it maintains consistent injection pressure and spray precision even under harsh working conditions, including high engine temperatures (up to 100°C), continuous vibration, and exposure to diesel fuel contaminants. It resists fuel leakage and nozzle clogging, avoiding engine misfires, power loss, or unplanned downtime. Backed by strict performance verification, it guarantees reliable fuel delivery to support uninterrupted operation of 240DLC/250GLC/270DLC/290GLC excavators.
