SPARKLING Crawler Excavator Valve Part – Precision & Durability

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 D60P D65E D65EX D65P 14X-12-11411 Shaft is a dedicated structural and transmission component exclusively designed for D60P, D65E, D65EX, and D65P bulldozers. As a core part of the bulldozers’ undercarriage or working mechanism, it enables smooth power transmission and stable component linkage—supporting critical tasks like land leveling, soil pushing, and construction site grading. This function is essential for maintaining the bulldozers’ operational stability and load-bearing capacity, directly ensuring consistent performance during prolonged high-intensity work and reducing the risk of mechanical jams or uneven movement caused by faulty transmission.

   Engineered to match original equipment performance standards, it maintains strong torsional strength and wear resistance even under harsh working conditions, including continuous load stress, vibration, and exposure to dust or muddy debris. It resists deformation and connection loosening, avoiding mechanical failures that could lead to unplanned downtime or costly component damage. Backed by strict performance verification, it guarantees long-term reliability to support uninterrupted operation of D60P/D65E/D65EX/D65P bulldozers.

   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.

   SPARKLING MACHINERY NEW R290LC7A 110D-7E R210LC9 XKDE-01492 Tensioner is a dedicated drive system component exclusively designed for R290LC7A, 110D-7E, and R210LC9 excavators. As a core part of the excavators’ belt-driven systems (powering critical accessories like alternators, water pumps, and air compressors), it automatically maintains optimal tension in drive belts. This key function prevents belt slippage (which leads to inefficient power transmission and accessory overheating) and reduces excessive belt wear, ensuring consistent operation of essential engine auxiliary systems during heavy-duty tasks such as digging, lifting, and earthmoving.

   Engineered to match original equipment performance standards, it adapts seamlessly to dynamic working conditions—including intense vibration, temperature fluctuations, and natural belt stretch over time—without the need for manual adjustments. It safeguards the belt drive system from damage caused by loose or over-tightened belts, minimizing unplanned downtime and supporting uninterrupted excavator operation. Backed by strict performance verification, it guarantees long-term reliability for the drive system.
