This harness assembly plays a critical role in the machine’s electrical system by securely transmitting signals and power between key components such as sensors, controllers, engine modules, and onboard displays. Designed to withstand the harsh environments of heavy-duty construction operations, it features durable insulation, corrosion-resistant terminals, and OEM-standard connectors for easy installation and long service life.

Whether you are conducting routine maintenance or replacing damaged wiring, this 14532878 wiring harness ensures optimal machine communication and electrical performance. It helps reduce downtime, prevent faults, and support efficient operation on the jobsite.

   SPARKLING MACHINERY NEW A25D EC140C EC240C EW40D 960254 O-Ring is a dedicated sealing component exclusively engineered for VOLVO A25D articulated dump trucks, EC140C/EC240C excavators, and EW40D wheeled excavators—key equipment in construction, mining, and municipal infrastructure projects. As a critical part of the machinery’s hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hoses). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like heavy hauling, digging, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous machinery vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for VOLVO A25D/EC140C/EC240C/EW40D systems. Backed by strict performance verification, it guarantees consistent sealing support for these VOLVO models.

The VOE14601385 Swing Motor Seal Kit is specially designed for Volvo excavator swing motors, ensuring reliable sealing and pressure retention for models such as EC240B, EC240C, EC250D, EC290B, EC290C, and EC300D. This kit helps restore swing system integrity by preventing internal hydraulic fluid leakage and protecting components from dust and moisture.

Whether used for preventive maintenance or emergency repair, this OEM-quality seal kit delivers long-lasting performance, high-temperature resistance, and outstanding oil sealing under high-pressure operations.

   SPARKLING MACHINERY NEW EC460B EC460C EC460CHR EC480D VOE14880727/14404535 Hose is a dedicated flexible fluid transmission component for VOLVO EC460B, EC460C, EC460CHR, and EC480D heavy crawler excavators (applied in large-scale mining, heavy construction, and infrastructure projects). As a core part of the excavator’s hydraulic system, it conveys high-pressure hydraulic oil between key components (e.g., hydraulic pumps, cylinders, control valves) to ensure uninterrupted power supply for tasks like rock breaking, bulk ore loading, and deep excavation.
   Meeting VOLVO OEM standards (part nos. VOE14880727/14404535), it withstands 32 MPa hydraulic pressure, -35°C to 100°C temperature changes, and repeated bending. Strict testing ensures seamless compatibility with the four VOLVO models and long-term leak-free, reliable fluid transfer.
