   SPARKLING MACHINERY NEW EC135B EC140B EC160B EC180B EC210B EW145B VOE120459863 Pully is a dedicated, heavy-duty mechanical component exclusively engineered for VOLVO EC135B, EC140B, EC160B, EC180B, EC210B crawler excavators and EW145B wheeled excavator—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As a core part of the excavator’s accessory drive system, it enables smooth belt operation to power critical auxiliary components (e.g., water pumps, alternators, hydraulic oil coolers). This function is vital for maintaining stable engine and hydraulic system performance during tasks like trench digging, material loading, and site grading, preventing belt slippage, drive system inefficiencies, or unexpected downtime caused by auxiliary component failure.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE120459863, the pully withstands harsh working conditions: high rotational speeds (up to 3,200 RPM), extreme temperature fluctuations (-25°C to 110°C), and continuous vibration from both on-road (EW145B) and off-road (crawler models) use. It maintains precise belt alignment and resists wear, providing long-lasting reliability for the excavators’ drive systems. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for all six VOLVO models.

   SPARKLING MACHINERY NEW 324D 330D 336D 336D2 2968060 Pressure Sensor is a dedicated precision monitoring component exclusively designed for 324D, 330D, 336D, and 336D2 excavators. As a core part of the excavators’ hydraulic and engine systems, it real-time detects critical pressure data—such as hydraulic system pressure and engine oil pressure—and transmits accurate signals to the operator’s control panel. This function is critical for preventing overpressure-related failures during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance, directly ensuring stable hydraulic power output, protecting valves and pumps from pressure damage, and avoiding unplanned downtime caused by pressure anomalies.

   Engineered to match original equipment performance standards, it maintains high detection accuracy even under harsh working conditions, including high oil pressure (up to 40 MPa), continuous excavator vibration, and exposure to hydraulic oil or dust. It resists signal interference and corrosion, avoiding data errors that could lead to misjudgments of the excavator’s operating status. Backed by strict performance verification, it guarantees reliable pressure monitoring to support uninterrupted operation of 324D/330D/336D/336D2 excavators.

   SPARKLING MACHINERY NEW R200W7 R170W7 31N6-10150 31N6-10160 Reduction Gear is a premium China-made transmission component specifically engineered for R200W7 and R170W7 wheel excavators. As a critical part of the power transmission system, it adjusts power output by converting high-speed, low-torque input into low-speed, high-torque motion, enabling efficient operation of key mechanical functions such as swing, travel, or auxiliary movements during construction, material handling, and industrial tasks.

   Designed to original equipment standards, it maintains stable power transfer and optimal torque conversion even under continuous operational stress and heavy loads. With optimized gear meshing design for minimal friction and wear, it adapts seamlessly to harsh working environments, from dusty job sites to rough terrain. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
