SPARKLING KX80-4 Hydraulic Oil Radiator – Durable Excavator Cooling

The Kubota Oil Cooler (part nos. RD82964040, RD829‑6404‑0, KU819640) is a heavy-duty hydraulic oil radiator designed specifically for Kubota compact excavators like the KX80‑3 and KX80‑4. Featuring an OE-style plate-core design, it efficiently dissipates heat to maintain optimal hydraulic performance under continuous load. Built with OEM-grade materials and engineered for direct fitment, it ensures reliable operation and easy installation—available as genuine Kubota or high-quality aftermarket alternatives.

   SPARKLING MACHINERY NEW 2420-1124A Valve; By-Pass 3B is a dedicated hydraulic pressure protection component for Doosan excavators (widely used in construction, municipal engineering, and light mining). As the "hydraulic pressure regulator", it automatically diverts excess hydraulic oil back to the tank when system pressure hits the 3B (bar) threshold—shielding pumps, cylinders, and hoses from overpressure damage during tasks like digging, material loading, and site trimming, while ensuring stable oil flow for smooth equipment operation.
   Meeting Doosan OEM standards (part no. 2420-1124A), it maintains precise 3B pressure control, endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees leak-free performance. Strict testing ensures seamless compatibility with applicable Doosan models and long-term hydraulic system reliability.

   SPARKLING MACHINERY NEW PC490 708-1T-13670/708-3S-13410 Retainer, Shoe is a dedicated, high-reliability structural component exclusively engineered for KOMATSU PC490 crawler excavators—heavy-duty equipment widely used in large-scale mining, construction, and quarrying projects. As a core fixing and protection part for the excavator’s undercarriage or hydraulic linkage systems, it securely retains critical components (e.g., track pins, linkage bushings) and shields them from excessive wear, preventing displacement or damage during high-intensity tasks like rock breaking, bulk ore loading, and deep excavation. This function is vital for maintaining undercarriage/linkage stability, reducing abnormal component wear, and avoiding unplanned downtime caused by part loosening or failure.

   Engineered to meet KOMATSU’s original equipment (OEM) standards and compatible with part numbers 708-1T-13670 and 708-3S-13410, the Retainer, Shoe withstands harsh working conditions: high mechanical loads (up to 12 kN), extreme temperature fluctuations (-25°C to 100°C), and continuous vibration from heavy-duty use. It resists corrosion, impact, and abrasive wear, providing long-lasting retention and protection for KOMATSU PC490 excavators. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily high-load tasks.

   SPARKLING MACHINERY NEW 312E 324E 329E 363-2518 363-2519 Breather is a premium China-made protective component specifically engineered for 312E, 324E, and 329E excavators. As a critical part of the machinery’s lubrication and hydraulic systems, it regulates air pressure, filters contaminants, and prevents moisture ingress, ensuring clean and balanced airflow to protect internal components from wear, corrosion, and damage during heavy-duty operations.

   Designed to original equipment standards, it maintains efficient air exchange and reliable filtration performance even in dusty, humid, or harsh working environments. With optimized structural design for durability and easy maintenance, it adapts seamlessly to varying job site conditions, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
