   SPARKLING MACHINERY NEW EC120D EC140C EC160C EC170D VOE111443400 Control Unit is a dedicated, high-precision electronic component exclusively engineered for VOLVO EC120D, EC140C, EC160C, and EC170D crawler excavators—versatile mid-sized equipment widely used in construction, municipal engineering, and light mining projects. As the "brain" of the excavator’s electrical and hydraulic coordination system, it processes real-time operational data (e.g., engine speed, hydraulic pressure, bucket position) to regulate core functions like boom movement, arm control, and engine power distribution. This ensures smooth, synchronized operation of all mechanisms, preventing operational lags or misalignment during tasks such as trench digging, material loading, and site grading.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE111443400, the control unit withstands harsh working conditions: extreme temperature fluctuations (-30°C to 85°C), high humidity, and continuous vibration from excavator operation. It resists electromagnetic interference and electrical surges, maintaining stable data transmission and control accuracy. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for EC120D/EC140C/EC160C/EC170D models.

The Caterpillar O‑Ring Kit (part no. 270‑1528 / 2701528) includes approximately 570 nitrile (Buna‑N) O‑rings available in 32 standard sizes, designed for use in heavy-duty Cat equipment such as wheel loaders (962, 936F, 960F, 972G, 980C, 980F) and excavators. Built to OEM specifications with 90 Durometer hardness, this kit offers reliable sealing for hydraulic fittings (SAE STOR, ORFS, Code 61/62 flanges), preventing leaks, maintaining system integrity, and significantly reducing downtime during maintenance
