SPARKLING EC240B Rotary Joint – Durable Excavator Part for Optimal Performance

The Volvo Center Swivel Joint (part no. VOE 14652066 / 14652066) is a critical hydraulic rotary joint engineered for Volvo excavators including the EC210B, EC240B, EC290C, and EC360B. Located between the upper structure and undercarriage, this swivel joint enables smooth 360° rotation while maintaining uninterrupted hydraulic flow. Manufactured to OEM specifications in China, it ensures long-term durability and precision fit with high-strength internal bushings and reliable seals—ideal for heavy-duty rotation cycles.

   SPARKLING MACHINERY NEW R320LC9 R330LC9A R330LC9S 31Q9-19140 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R320LC9, R330LC9A, and R330LC9S excavators. As a critical part of the swing system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

The 31QB-10037 / 31QB-10030 Hydraulic Main Pump Assembly is an essential component for delivering stable hydraulic power to your Hyundai crawler excavators. Built for high-performance, this pump guarantees powerful flow, high efficiency, and exceptional durability even under extreme excavation workloads.

🔧 Key Features:

• Original quality fitment for Hyundai’s large crawler excavators

• Ensures precise pressure regulation and smooth hydraulic operation

• Manufactured with high-grade wear-resistant components

• Rigorously tested for flow rate, pressure endurance, and temperature resilience

   SPARKLING MACHINERY NEW 312E 320E 324E 2566454 Temperature Sensor is a dedicated precision monitoring component exclusively designed for 312E, 320E, and 324E excavators. As a core part of the excavators’ engine and hydraulic system monitoring, it real-time detects critical temperature data—such as engine coolant temperature and hydraulic oil temperature—and transmits accurate signals to the operator’s control panel. This function is critical for preventing overheating during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance, directly ensuring stable engine power output, protecting hydraulic components from thermal damage, and avoiding unplanned downtime caused by temperature-related failures.

   Engineered to match original equipment performance standards, it maintains high detection accuracy even under harsh working conditions, including extreme temperatures (-30°C to 120°C), continuous excavator vibration, and exposure to dust or hydraulic oil. 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 temperature monitoring to support uninterrupted operation of 312E/320E/324E excavators.
