   SPARKLING MACHINERY NEW 440211-01543 DX490LC-7M (OEM) Radiator is an exclusive OEM-standard cooling core component designed specifically for DX490LC-7M large excavators—commonly used in heavy mining, large-scale construction, and infrastructure projects. As the core of the excavator’s engine cooling system, it efficiently dissipates excess heat generated by the high-power engine during prolonged heavy-load operations (such as rock breaking, bulk material loading, and deep excavation) by transferring heat from coolant to ambient air. This function is critical for maintaining the engine’s optimal operating temperature (85–95°C), preventing overheating-induced power loss, cylinder head warping, or irreversible engine damage, while ensuring consistent productivity in demanding work environments.

   Engineered to meet 100% OEM specifications, it maintains superior heat dissipation efficiency even under harsh conditions—including high ambient temperatures (up to 50°C), continuous excavator vibration, and exposure to dust, gravel, or heavy rain. It resists coolant leakage and core corrosion, avoiding cooling system failures that lead to costly unplanned downtime. Backed by strict OEM-level performance verification, it guarantees reliable heat management to support uninterrupted operation of DX490LC-7M excavators.

   SPARKLING MACHINERY NEW SK170 ACERA M-9 YB10V01001F3 Regulator is a core control component for Kobelco SK170 ACERA M-9 excavators (heavy-duty construction/mining use). It stabilizes key operational parameters (e.g., hydraulic pressure, electrical voltage) to ensure consistent system performance. 
   Meeting Kobelco OEM standards (YB10V01001F3), it resists -30°C to 100°C temps, voltage fluctuations, and mechanical interference, ensuring seamless compatibility and long-term reliable parameter regulation.

   SPARKLING MACHINERY NEW VOE21379931 Injector is a core engine fuel supply component for Volvo excavators (heavy-duty construction/mining use). It precisely atomizes and injects fuel into cylinders to ensure efficient combustion and stable power output. 
   Meeting Volvo OEM standards (VOE21379931), it resists up to 280°C high temps and 180MPa pressure, guaranteeing seamless compatibility and long-term reliable fuel delivery performance.
