SPARKLING Heavy-Duty Construction Equipment Parts – Durable & Precise

   SPARKLING MACHINERY NEW 416E 416F 420F 422E 422F 308-2890 Kit-Regulato is a dedicated hydraulic regulation component kit for Caterpillar 416E, 416F, 420F, 422E, and 422F backhoe loaders/excavators (widely used in construction, municipal engineering, and agricultural operations). As a core set for the equipment’s hydraulic system, it fine-tunes pressure, flow, and valve response to ensure consistent performance of key functions—like buc   Your Caterpillar’s trusted hydraulic regulation solution starts here. 
   Now, we’re proud to present the CATERPILLAR EXCAVATOR PARTS MADE IN CHINA NEW 416E 416F 420F 422E 422F 308-2890 KIT-REGULATO by SPARKLING MACHINERY. Next, we’ll cover its core strengths: seamless compatibility with five Caterpillar models, precise hydraulic tuning, rigorous quality, and more—helping you see how it boosts your equipment’s operational consistency and cuts maintenance troubles.ket digging, boom lifting, and steering—even under variable workloads.
   Meeting Caterpillar OEM standards (part no. 308-2890), it endures 28 MPa hydraulic pressure, -30°C to 95°C temperatures, resists oil corrosion and vibration, and maintains stable regulation. Strict testing guarantees seamless compatibility with the five models and long-term hydraulic system efficiency.

The 208-60-71330 Solenoid Valve Assembly is an original quality hydraulic control component, specially designed for Komatsu PC400-7 and PC400LC-7 excavators (serial number 50001 and above). This valve plays a vital role in regulating hydraulic flow to various systems such as swing, travel, boom, arm, and breaker functions, based on electric input signals from the operator controls.

Built with high-temperature copper coils, reinforced casing, and precise valve mechanics, this solenoid valve guarantees stable performance, rapid response, and long service life in harsh working conditions. Manufactured by SPARKLING MACHINERY, it meets or exceeds OEM performance standards.

   SPARKLING MACHINERY NEW CS56B CS68B CS74B CS78B 418-3837/360-3987 Piston Assy is a core engine combustion component for Caterpillar CS56B, CS68B, CS74B, and CS78B excavators (widely used in construction, mining, and infrastructure compaction tasks). As the "engine power generator", it moves reciprocally in the cylinder to compress fuel-air mixtures and transmit combustion force to the crankshaft—ensuring stable engine power output during high-intensity operations like heavy digging, rock breaking, and material handling, while maintaining efficient fuel combustion.
   Meeting Caterpillar OEM standards (part nos. 418-3837/360-3987), it endures -30°C to 200°C cylinder temperatures, resists high-pressure impact and wear, and guarantees airtight combustion chamber performance. Strict testing ensures seamless compatibility with the four Caterpillar models and long-term engine reliability.
