SPARKLING 22U-03-22112 - Reliable Excavator 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 R140W7 R140W7A R170W7 XKBF-00100 Lock Valve Kit-A is a dedicated, high-precision hydraulic safety assembly exclusively engineered for HITACHI R140W7, R140W7A, and R170W7 wheeled excavators—versatile equipment widely used in road construction, municipal engineering, and urban infrastructure projects. As a core safety component of the excavator’s hydraulic system, it locks the position of key mechanisms (boom, arm, bucket) when the excavator is stationary or during operator breaks, preventing accidental movement caused by hydraulic pressure loss. This function is vital for protecting on-site workers, avoiding equipment collisions, and ensuring operational safety during tasks like road repair, material handling, and urban demolition.

   Engineered to meet HITACHI’s original equipment (OEM) standards and marked with the genuine part number XKBF-00100, the Lock Valve Kit-A withstands harsh working conditions: high hydraulic pressure (up to 32 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from on-road travel and off-road work. It resists oil contamination and mechanical wear, providing long-lasting safety protection for the three HITACHI wheeled excavator models. Backed by strict performance verification, it guarantees seamless compatibility and reliable operation for daily excavator tasks.

The VOE14683841 Seal Kit from SPARKLING MACHINERY is designed for Volvo EC220D, EC220E, and EC235D excavators. Made from high-quality rubber, PU, and PTFE, it ensures reliable sealing, wear resistance, and easy installation—ideal for hydraulic cylinder maintenance with OEM-level performance.

   SPARKLING MACHINERY NEW R320LC9 R330LC9A R330LC9S 31Q9-19140 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R320LC9, R330LC9A, and R330LC9S excavators. As a critical part of the swing system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
