   SPARKLING MACHINERY NEW PC45MR PC55MR 708-3S-04571 Gear Pump is a dedicated hydraulic power supply component for Komatsu PC45MR and PC55MR mini crawler excavators (widely used in urban construction, garden maintenance, and narrow-space earthmoving). As the "hydraulic power source", it converts engine mechanical energy into hydraulic pressure—supplying stable high-pressure oil to cylinders, valves, and actuators for tasks like small-scale digging, material loading, and landscape trimming, while ensuring responsive and efficient equipment operation.
   Meeting Komatsu OEM standards (part no. 708-3S-04571), it maintains a rated pressure of 25 MPa, endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees low-noise, leak-free performance. Strict testing ensures seamless compatibility with Komatsu PC45MR/PC55MR 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 EC250D EC250E EC300D EC300E PL3005D 14591251 Relief Valve is a dedicated hydraulic safety component for VOLVO EC250D, EC250E, EC300D, EC300E, and PL3005D crawler excavators (heavy-duty equipment for mining, large-scale construction, and infrastructure projects). As the core safety guard of the hydraulic system, it precisely limits maximum pressure to protect pumps, cylinders, and pipelines from overload damage during rock breaking, bulk ore loading, and deep excavation.

   Meeting VOLVO OEM standards (part no. 14591251), it endures 34 MPa pressure, -25°C to 105°C temperature fluctuations, and continuous vibration. It resists oil contamination and wear, ensuring long-term reliability for the five VOLVO models, with strict testing guaranteeing seamless compatibility and safe operation.
