936F Hydraulic Seals by SPARKLING

The Caterpillar O‑Ring Kit (part no. 270‑1528 / 2701528) includes approximately 570 nitrile (Buna‑N) O‑rings available in 32 standard sizes, designed for use in heavy-duty Cat equipment such as wheel loaders (962, 936F, 960F, 972G, 980C, 980F) and excavators. Built to OEM specifications with 90 Durometer hardness, this kit offers reliable sealing for hydraulic fittings (SAE STOR, ORFS, Code 61/62 flanges), preventing leaks, maintaining system integrity, and significantly reducing downtime during maintenance

   SPARKLING MACHINERY NEW R360LC7 R360LC7A R370LC7 31NA-10150 Swing Reduction is a core transmission component for 3 Hyundai excavator models (heavy-duty construction/mining use). It reduces engine speed to deliver high torque for smooth, precise upper-structure rotation. 
   Meeting Hyundai OEM standards (31NA-10150), it resists -30°C to 100°C temps, wear, and impact, ensuring seamless compatibility and long-term reliable swing operation performance.

   SPARKLING MACHINERY NEW R200W7 ZGAQ-01270 Gear-Ring is a dedicated transmission system component for Hyundai R200W7 wheeled excavators (widely used in construction, municipal engineering, and road maintenance). As a core part of the excavator’s power transmission mechanism, it meshes with gears to transfer torque between the engine and driving system—ensuring smooth power delivery during tasks like digging, loading, and on-site mobility, while maintaining stable operation under heavy loads.
   Meeting Hyundai OEM standards (part no. ZGAQ-01270), it endures -30°C to 85°C temperatures, resists wear and vibration, and maintains precise tooth meshing accuracy. Strict testing guarantees seamless compatibility with Hyundai R200W7 and long-term transmission system reliability.

   SPARKLING MACHINERY NEW 440-00257 Cylinder;Arm is a dedicated hydraulic actuation component tailored for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s arm movement system, it converts hydraulic pressure into linear force to drive the arm’s lifting, lowering, and extending actions—supporting critical on-site tasks like digging, material grabbing, and precision placement in construction, mining, or infrastructure projects. This function is essential for maintaining the machinery’s operational flexibility and load-bearing capacity, directly ensuring smooth coordination between the arm and bucket, and preventing movement lag or jams that could reduce work efficiency or cause safety hazards.

   Engineered to match original equipment performance standards, it maintains stable pressure retention and smooth piston movement even under harsh working conditions, including heavy load stress (up to rated 500 kN), continuous vibration, and exposure to dust or hydraulic oil contaminants. It resists internal leakage and cylinder wall wear, avoiding hydraulic system inefficiencies that lead to unplanned downtime. Backed by strict performance verification, it guarantees reliable arm actuation to support uninterrupted operation of compatible heavy-duty machinery.
