SPARKLING MACHINERY Pump – Reliable Excavator Part Since 2013

The 705-12-35250 Gear Pump Assembly is a critical hydraulic component designed for KOMATSU HM400-3R Articulated Dump Trucks. This gear pump plays a vital role in ensuring smooth and efficient hydraulic flow for critical systems, including steering, braking, and body lifting functions.

Manufactured with high-precision machining and quality-tested materials, the 7051235250 gear pump offers excellent reliability, extended service life, and consistent performance under extreme working conditions. Whether you're replacing a worn-out unit or conducting scheduled maintenance, SPARKLING MACHINERY's aftermarket gear pump ensures optimal compatibility and long-term value.

   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.

The Oil Cooler Assembly (Part No. 13C30000-2 / 13C300002) is specially engineered for Doosan and Daewoo excavator models S290LL, S290LC-V, and DH300-5. Designed to deliver efficient heat dissipation, this oil cooler helps maintain optimal hydraulic oil temperature, thereby enhancing the longevity and performance of your machinery.

Manufactured with high-strength aluminum and precision-welded construction, this oil cooler offers excellent thermal conductivity, durability, and resistance to vibration—ideal for demanding construction and forestry environments.

   SPARKLING MACHINERY NEW K3551.178-6190 Radiator is a dedicated thermal management component for Liebherr excavators (widely used in construction, mining, and heavy infrastructure projects). As the "engine cooling core", it dissipates excess heat from the excavator’s engine and hydraulic system—preventing overheating during high-intensity tasks like continuous digging, rock breaking, and heavy lifting, while ensuring stable equipment operation even in high-temperature environments.
   Meeting Liebherr OEM standards (part no. K3551.178-6190), it maintains efficient heat dissipation (heat rejection rate ≥85%), endures -30°C to 120°C temperatures, resists corrosion and vibration, and ensures leak-free coolant circulation. Strict testing guarantees seamless compatibility with applicable Liebherr models and long-term thermal system reliability.
