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.

The Radiator Core (Part No. 22U-03-22113 / 22U-03-22112 / 22U-03-22111) is a high-quality cooling component designed specifically for Komatsu PC228 and PC228US excavators. This core is engineered to maintain optimal engine temperature, ensuring reliable machine performance under extreme working conditions.

Constructed with durable aluminum alloy and efficient heat dissipation fins, this radiator core guarantees excellent thermal performance, corrosion resistance, and long service life. It is a direct-fit replacement, tested to meet or exceed OEM standards.

   SPARKLING MACHINERY NEW YN15V00077F1 Swing Motor - a core hydraulic component for excavators, features "precision slewing + durable stability". Engineered to original standards, it fits multiple mainstream excavator models, enabling 360° smooth rotation. Crafted with high-strength alloy housing and precision-machined internal parts, paired with advanced hydraulic valve control, it maintains stable speed under high pressure and heavy loads, reducing operational vibration.

   Equipped with multi-layer sealing protection, it resists dust and water intrusion, adapting to harsh conditions. Verified through 12 strict quality checks, it ensures long-term leak-free, low-loss operation. Backed by professional support and cost-effectiveness, it provides reliable rotational power, minimizing downtime and serving as an ideal choice to enhance excavator efficiency.

   SPARKLING MACHINERY NEW ZX350LC-5B ZX350LCN-5B 8970241240 8943925532 Gasket is a dedicated sealing component exclusively designed for ZX350LC-5B and ZX350LCN-5B excavators. As a core part of the excavators’ engine, hydraulic, or fuel systems, it creates a tight, leakproof barrier between mating components (e.g., engine cylinder heads, hydraulic valve covers, or fuel system housings). This function is critical for preventing fluid (oil, coolant, fuel) or gas leakage during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance—directly protecting internal components from contamination, maintaining system pressure stability, and avoiding unplanned downtime caused by leakage-related failures.

   Engineered to match original equipment performance standards, it maintains strong sealing performance even under harsh working conditions, including extreme temperatures (-20°C to 180°C), continuous excavator vibration, and exposure to oil or coolant additives. It resists deformation and material degradation, avoiding seal failure that could lead to costly component damage or environmental pollution. Backed by strict performance verification, it guarantees reliable sealing to support uninterrupted operation of ZX350LC-5B/ZX350LCN-5B excavators.
