This robust 6-blade fan spider assembly plays a vital role in maintaining optimal engine temperatures by efficiently driving airflow through the radiator and cooling system.

Crafted from durable materials to withstand demanding industrial environments, the fan spider ensures reliable performance and long service life. Its precision design promotes effective heat dissipation, helping to prevent engine overheating during heavy-duty material handling operations.

Whether you are replacing a worn-out fan or upgrading your cooling system components, this OEM-quality spider fan assembly fits perfectly and supports your machine’s consistent performance on the job site.

   SPARKLING MACHINERY NEW 31NB-30020 Gear Pump is a premium China-made hydraulic component engineered as a key fluid power transmission unit for compatible machinery. As a core part of hydraulic systems, it generates consistent fluid pressure to drive essential operations such as actuator movement, lubrication, and auxiliary function control, ensuring smooth performance in construction, agriculture, and industrial equipment applications.

   Designed to original equipment standards, it maintains stable flow output even under continuous heavy loads, minimizing energy loss and optimizing overall system efficiency. Equipped with advanced pressure balancing and leak-resistant designs, it adapts to harsh working environments, from dusty job sites to high-vibration conditions. Backed by strict quality verification, it ensures reliable fluid power transmission to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW 14704262 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom, and working arms), it enables uninterrupted 360° rotation while maintaining seamless hydraulic fluid transmission to core systems—including swing motors, hydraulic cylinders, and control valves. This ensures consistent power delivery for essential operations like digging, lifting, and precision swing movements in construction, mining, and earthmoving tasks.

   Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure (up to industry-standard thresholds) and continuous rotational stress, as well as harsh working conditions such as dust, vibration, and exposure to construction debris or moisture. With optimized high-wear-resistance sealing rings and precision-machined internal flow channels, it minimizes pressure loss and prevents fluid contamination, protecting the hydraulic system from damage. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted machinery rotation and maximize work efficiency.

   SPARKLING MACHINERY NEW PC490 708-1T-13440/708-1T-13610 Cylinder Block is a dedicated, high-strength structural core exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment critical for large-scale mining, construction, and quarrying projects. As the foundational component of the excavator’s engine, it houses key moving parts (pistons, crankshafts) and forms the sealed chamber for fuel combustion, directly supporting engine power output and operational stability during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for preventing engine structural failure, maintaining consistent power delivery, and avoiding costly unplanned downtime that disrupts critical project workflows.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13440 and 708-1T-13610, the Cylinder Block withstands harsh working conditions: high combustion pressure (up to 18 MPa), extreme temperature fluctuations (-30°C to 120°C), and continuous vibration from heavy-duty use. It resists thermal deformation and mechanical wear, providing long-lasting structural reliability for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load engine tasks.
