SPARKLING 3109497 Flexible Coupling for Excavators

The CATERPILLAR 310-9497 Coupling GP – Flexible (also known as CA3109497 or 3109497) is a critical drivetrain component designed to connect the engine to the hydraulic or mechanical power transmission systems. Specifically engineered for CAT Excavators 336E, 345D, 349DL, 568FMLL, and mobile hydraulic power units, this flexible coupling provides smooth torque transmission while compensating for misalignment and vibration between components.

Compatible with Caterpillar C9.3 and C13 engines, this coupling ensures enhanced durability and performance under heavy-duty conditions. Whether operating in construction, forestry, or mining environments, the 310-9497 flexible coupling is built to OEM specifications to deliver consistent power with minimal wear and noise.

Its robust rubber-metal composite design helps absorb shock loads, reduce system stress, and protect vital engine and pump components—making it essential for maintaining operational efficiency and preventing costly downtime.

   SPARKLING MACHINERY NEW EC240B EC240C EC250D EC290B EC290C 14601385 Seal Kit is a dedicated, heavy-duty sealing solution exclusively designed for VOLVO EC240B, EC240C, EC250D, EC290B, and EC290C crawler excavators—core equipment in large-scale construction, mining, and infrastructure development projects. As a critical protective component for the excavators’ high-pressure hydraulic systems, it covers key areas such as hydraulic cylinder rods, valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of high-load mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, gravel, or moisture from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity tasks like rock breaking, bulk material loading, and deep excavation.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous heavy-duty excavator vibration. It resists oil aging and material wear, providing long-lasting protection for the hydraulic systems of EC240B/EC240C/EC250D/EC290B/EC290C models. Backed by strict performance verification, it guarantees uninterrupted sealing support for these VOLVO excavators.

   SPARKLING MACHINERY NEW HX330L 39K9-12100 Swing Reduction Gear is a premium China-made transmission component specifically engineered for HX330L 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 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.
