VOLVO EXCAVATOR PARTS MADE IN CHINA NEW EC240B EC240C EC250D EC250E EC290B VOE22383378 LEVER SENSOR SPARKLING MACHINERY
SPARKLING MACHINERY NEW EC240B EC240C EC250D EC250E EC290B VOE22383378 Lever Sensor is a dedicated precision detection component for VOLVO EC240B, EC240C, EC250D, EC250E, and EC290B crawler excavators (widely used in construction, mining, and infrastructure projects). As a core part of the excavator’s hydraulic control system, it detects the position and movement of operation levers (e.g., boom, bucket, and arm levers) and transmits real-time signals to the ECU—ensuring precise, responsive control of hydraulic functions during tasks like digging, loading, and slope trimming.
Meeting VOLVO OEM standards (part no. VOE22383378), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains high detection accuracy. Strict testing guarantees seamless compatibility with the five VOLVO models and long-term reliable signal output.

MADE IN CHINA SPARKLING MACHINERY NEW 320D 320D2 312-8338 OIL COOLER
SPARKLING MACHINERY NEW 320D 320D2 312-8338 Oil Cooler is a dedicated thermal management component exclusively designed for 320D and 320D2 excavators. As a core part of the excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of 320D/320D2 machinery.
Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of 320D and 320D2 excavators.
