SPARKLING 22U-03-22111 Excavator Part – Durable Precision Component

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 14652656 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom), it enables continuous 360° rotation while maintaining seamless hydraulic fluid transmission to key systems—such as the swing motor, hydraulic cylinders, and control valves. This ensures unobstructed, reliable power delivery for core operations like digging, lifting, and swing movements in construction, mining, and earthmoving tasks.

   Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure and continuous rotational stress, as well as harsh working conditions (e.g., dust, vibration, and exposure to construction debris). With optimized sealing rings and precision-machined internal channels, it minimizes pressure loss and prevents fluid contamination, safeguarding the hydraulic system from damage. Backed by strict quality verification, it guarantees consistent operation to support uninterrupted machinery rotation and maximize work efficiency.

   SPARKLING MACHINERY NEW R140LC-9 R160LC-9 R180LC-9 R140W-9 R170W-9 R210W-9 14510802 Knob Assy LH RCV is a dedicated cab control component for Hyundai R140LC-9, R160LC-9, R180LC-9, R140W-9, R170W-9, and R210W-9 crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As a core part of the cab’s receiver-side left-hand control system, it enables operators to adjust key functions (e.g., hydraulic flow, work modes) with precise twisting or pressing actions—ensuring smooth, intuitive operation during tasks like digging, loading, and slope trimming.
   Meeting Hyundai OEM standards (part no. 14510802), it endures -30°C to 85°C temperatures, resists dust and vibration, and maintains reliable tactile feedback. Strict testing guarantees seamless compatibility with the six Hyundai models and long-term cab control efficiency.

   The HIGH-QUALITY Carbon Steel 435-0795 FINAL DRIVE SUN GEAR is a premium power transmission component meticulously engineered for Caterpillar Construction Equipment, specifically tailored to meet the high-torque and durability demands of 308 CR, 307.5, 309 CR, 308E, and 308E2CR excavators. As a core part of the machinery’s final drive system, this sun gear plays a critical role in transferring engine power to the tracks, ensuring smooth torque distribution, stable traction, and reliable movement even in heavy-load construction scenarios. 
   It is designed to seamlessly integrate with Caterpillar’s final drive architecture, delivering consistent performance that enhances machinery productivity and operational longevity.
