SPARKLING R300LC-9 Spare Parts

The HYUNDAI Check Valve 31N8-17420 / XKCG-00456 is a genuine replacement component designed for the main control valve system of Hyundai 9-Series crawler excavators, specifically model R300LC-9.

This check valve plays a critical role in hydraulic flow control. It allows fluid to move in one direction while preventing backflow, which protects the hydraulic system from pressure surges and maintains stable performance during demanding excavation operations.

Manufactured to OEM specifications, this valve offers precision engineering, corrosion resistance, and a durable internal seal — ensuring reliable operation, even under extreme pressure and high-duty cycles. It's ideal for both routine maintenance and emergency repairs when performance and safety are non-negotiable.

   SPARKLING MACHINERY NEW R80-7 R80-7A 11N1-42120 Oil Cooler is a dedicated thermal management component exclusively designed for R80-7 and R80-7A excavators. As a core part of these excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during tasks like small-scale construction, agricultural tillage, and urban infrastructure maintenance. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of R80-7/R80-7A excavators.

   Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of R80-7 and R80-7A excavators.

   SPARKLING MACHINERY NEW 440-00257 Arm Cylinder is a core hydraulic actuator exclusively for Doosan 300 excavators (heavy-duty construction/mining use). It delivers stable, high force for arm lifting, lowering, and precision positioning, critical for heavy-load operations. 
   Meeting Doosan OEM standards (440-00257), it resists -30°C to 100°C temps, high hydraulic pressure, and wear, ensuring seamless compatibility and long-term reliable arm control performance.

   SPARKLING MACHINERY NEW 4D95LE S4D95LE WA65 WA70 WA80 6204-31-3200 Rod-Assy is a dedicated mechanical linkage component for Komatsu 4D95LE/S4D95LE engines and WA65/WA70/WA80 wheel loaders/excavators (widely used in construction, agricultural, and material handling operations). As a core part of the equipment’s control or drive system, it transmits linear motion to key components (e.g., fuel injectors, hydraulic valves) to ensure precise activation of functions like engine fuel regulation or loader bucket control—supporting stable performance during daily tasks.
   Meeting Komatsu OEM standards (part no. 6204-31-3200), it endures high tensile loads (up to 80 kN), -30°C to 90°C temperatures, resists wear and corrosion, and maintains consistent motion transmission. Strict testing guarantees seamless compatibility with the six Komatsu models and long-term reliable mechanical operation.
