   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.

The 4472-377-047 Carrier Disc is a critical transmission component designed for the HYUNDAI R170W-7 Wheel Excavator. As part of the planetary gear assembly, the carrier disc ensures smooth torque transfer and balanced load distribution within the drive system, supporting reliable movement and effective excavation operations.

Manufactured with high-strength materials and strict quality control, this carrier disc (also referenced as 4472377047 or 4472.377.047) offers precise fitment and extended durability, making it a cost-effective and dependable replacement for OEM parts.
