SPARKLING PC228 Radiator Core – Durable Excavator Cooling Solution

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 VOE14743548/11224414 Swing Reducer is a core transmission component for Volvo EC380D and SDLG E6400F excavators (mining/heavy construction use). It reduces speed to amplify torque, enabling smooth, precise upper-structure swinging for heavy-load tasks. 
   Meeting OEM standards (dual part numbers), it resists -30°C to 100°C temps, heavy loads, and wear, guaranteeing seamless compatibility and long-term reliable swing performance.

   SPARKLING MACHINERY NEW 416F 420F 428F 430F 432F 434F 444F 360-3988 Crankshaft Main Bearing is a critical engine load-bearing and lubrication component for Caterpillar 416F, 420F, 428F, 430F, 432F, 434F, and 444F excavators (widely used in construction, mining, and municipal infrastructure projects). As the "crankshaft stability anchor", it supports the crankshaft’s rotational motion, reduces friction between the crankshaft and engine block, and absorbs radial loads from power transmission—ensuring smooth engine operation during high-intensity tasks like digging, heavy lifting, and rock breaking, while protecting core engine parts from wear.
   Meeting Caterpillar OEM standards (part no. 360-3988), it endures -30°C to 150°C engine temperatures, resists oil oxidation and metal fatigue, and maintains consistent lubrication performance. Strict testing guarantees seamless compatibility with the seven Caterpillar models and long-term engine reliability.

   SPARKLING MACHINERY NEW R170W7 R170W7A R170W9S ZGAQ-02283 Cylinder-Steering is a premium China-made hydraulic component specifically engineered for R170W7, R170W7A, and R170W9S wheel excavators. As a critical part of the steering system, it converts hydraulic pressure into linear motion to enable smooth and precise directional control, ensuring stable maneuvering during operation, positioning, and job site navigation.

   Designed to original equipment standards, it maintains consistent force output and responsive operation even under heavy loads and continuous use. With optimized seal design for leak resistance and robust structural integrity, it adapts seamlessly to harsh working environments, from muddy construction sites to rough terrain. Backed by strict quality verification, it guarantees reliable performance to support safe and uninterrupted machinery operation.
