   SPARKLING MACHINERY NEW EC250D EC300D PL3005D 22067983 Wire Harness is a critical electrical connection component for Volvo EC250D, EC300D, and PL3005D excavators (widely used in construction, mining, and infrastructure projects). As the "electrical communication backbone", it transmits stable power and signals between the excavator’s control unit, sensors, and actuators—ensuring smooth operation of functions like engine start, hydraulic control, and instrument display during tasks like digging, lifting, and rock breaking, while preventing electrical failures that disrupt equipment performance.
   Meeting Volvo OEM standards (part no. 22067983), it endures -30°C to 85°C temperatures, resists moisture and vibration, and guarantees reliable insulation. Strict testing ensures seamless compatibility with the three Volvo models and long-term electrical system reliability.

   SPARKLING MACHINERY NEW ZX350LC-5B ZX350LCN-5B 8980964171/8982609301 Turbocharger is a dedicated, high-performance engine component exclusively engineered for HITACHI ZX350LC-5B and ZX350LCN-5B crawler excavators—heavy-duty equipment widely used in large-scale mining, construction, and infrastructure projects. As a core part of the excavator’s engine system, it enhances air intake efficiency by compressing incoming air, directly boosting engine power output, fuel combustion efficiency, and overall operational performance. This function is critical for maintaining stable engine operation during high-intensity tasks like rock breaking, bulk material loading, and deep excavation, preventing power loss under heavy loads and reducing fuel consumption.

   Engineered to meet HITACHI’s original equipment (OEM) standards and compatible with part numbers 8980964171 and 8982609301, the turbocharger withstands harsh working conditions: extreme engine temperatures (up to 850°C), high rotational speeds (up to 150,000 RPM), and continuous vibration from heavy-duty use. It resists thermal fatigue, oil contamination, and mechanical wear, providing long-lasting reliability for the excavators’ engine systems. Backed by strict performance testing, it guarantees consistent compatibility and optimal engine performance for ZX350LC-5B/ZX350LCN-5B models.

   SPARKLING MACHINERY NEW 336GC 340GC 345GC 350GC 510-1695/617-1905 Injector is a core engine fuel injection component for Caterpillar 336GC, 340GC, 345GC, and 350GC excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "fuel atomization core", it precisely sprays fuel into the combustion chamber—ensuring efficient fuel combustion during high-intensity tasks like rock breaking, deep digging, and heavy lifting, while maintaining stable engine power output and reducing fuel waste.
   Meeting Caterpillar OEM standards (part nos. 510-1695/617-1905), it endures -30°C to 200°C engine temperatures, resists fuel corrosion and vibration, and guarantees consistent injection pressure. Strict testing ensures seamless compatibility with the four Caterpillar models and long-term engine reliability.
