   SPARKLING MACHINERY NEW 21M9-30102 Cluster Assy is a dedicated instrument panel assembly exclusively designed for compatible heavy-duty construction machinery, such as excavators and loaders. As the core of the machinery’s operator information system, it integrates critical gauges, warning lights, and digital displays to real-time monitor key operational data—including engine speed, oil pressure, coolant temperature, fuel level, and hydraulic system status. This function is essential for operators to make timely adjustments during heavy-duty tasks like digging, loading, and site grading, directly ensuring safe machinery operation, preventing potential component damage, and maintaining consistent work efficiency.

   Engineered to match original equipment performance standards, it maintains clear readability and stable data transmission even under harsh working conditions, including continuous vibration, dust exposure, and temperature fluctuations. It resists electrical malfunctions and display dimming, avoiding information delays or errors that could lead to operational risks or unplanned downtime. Backed by strict performance verification, it guarantees reliable data feedback to support uninterrupted operation of compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW 8-98238255-2 EGR Valve is a premium China-made emissions control component designed for compatible diesel-powered construction machinery (such as excavators, loaders) and industrial engines. As a core part of the Exhaust Gas Recirculation (EGR) system, it precisely regulates the flow of exhaust gas back into the engine’s intake manifold—reducing the combustion temperature to minimize the formation of nitrogen oxides (NOx), a major harmful emission. This ensures compliance with global emission standards (e.g., Tier 4 Final, Euro V) while maintaining engine power output for heavy-duty tasks like digging, lifting, and material handling in construction, mining, and urban infrastructure projects.

   Engineered to original equipment standards, it maintains reliable performance even under harsh working conditions, including high exhaust temperatures (up to 650°C), vibration, and exposure to soot or exhaust contaminants. With a precision-machined valve stem and adaptive sealing design, it minimizes gas leakage and ensures smooth, responsive flow control. Backed by strict quality verification, it guarantees consistent emissions reduction and prevents EGR system-related engine issues, supporting uninterrupted machinery operation.

   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.
