   SPARKLING MACHINERY NEW SK485-9 DX420 DX480 472-0209 Crankshaft is a dedicated power transmission core component for Weichai-powered excavators, including SK485-9, DX420, and DX480 models (widely used in heavy construction, mining, and large-scale earthmoving). As the "engine power converter", it converts the reciprocating motion of engine pistons into rotational motion—driving key excavator systems like hydraulic pumps and generators to ensure stable power output during high-intensity tasks such as rock breaking, deep digging, and heavy lifting.
   Meeting Weichai OEM standards (part no. 472-0209), it maintains precise rotational balance, endures -30°C to 150°C engine temperatures, resists wear and vibration, and ensures long-term structural stability. Strict testing guarantees seamless compatibility with the three Weichai-powered excavator models and reliable engine operation.

   SPARKLING MACHINERY NEW A35G A40G A45G EC210D L150G 22899626 Pressure Sensor is a key hydraulic monitor for Volvo’s 5 excavator models (construction/mining use). It real-time tracks hydraulic pressure, sends accurate signals to the control unit, prevents overpressure damage, and maintains stable operation. Meeting Volvo OEM standards (22899626), it resists -30°C to 100°C temps, vibration, and oil corrosion, ensuring compatibility and reliability.

   SPARKLING MACHINERY NEW EC135B EC140B EC140C EC140D EC140E EC160B VOE14533604 O-Ring is a dedicated sealing component for VOLVO EC135B, EC140B/C/D/E, and EC160B crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As a core sealing part in the excavator’s hydraulic or fluid systems, it creates a tight barrier between connected components (e.g., hydraulic valves, pipe joints, cylinder covers) to prevent oil or coolant leaks during tasks like digging, loading, and slope grading.
   Meeting VOLVO OEM standards (part no. VOE14533604), it endures -35°C to 95°C temperatures, resists hydraulic oil corrosion and compression set, and maintains stable sealing performance. Strict testing guarantees seamless compatibility with the six VOLVO models and long-term leak-free operation.
