SPARKLING Excavator Parts – Reliable, High-Quality Components Since 2013

The Caterpillar Solenoid Valve (part nos. 249‑3125 / 2493124) is a rugged, 12 V DC coil-controlled valve assembly designed for hydraulic systems on Cat backhoe loaders—including models 446D, 424D, 420D/F, 442D, 430D/F, 428D, 416D, and others. Built to OEM standards, this valve features a 2-pin DT connector and 7/8‑14 thread, offering precise electro-hydraulic control essential for steering, transmission, or loader functions. It delivers reliable performance under demanding conditions and is available in both genuine and high-quality aftermarket versions.

   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 ZGAQ-02176 Differential Casing is a premium replacement part engineered for Hyundai wheel excavators including R170W-7, R170W-7A, R170W-9S, and R180W-9S. This component serves as the protective housing for the differential gear system, ensuring proper alignment, lubrication, and smooth power distribution to the wheels during operation.

Manufactured with high-strength cast steel and precision-machined for a perfect OEM fit, this differential casing provides enhanced resistance against heavy loads, impact stress, and heat deformation—ideal for demanding construction and excavation work.

   SPARKLING MACHINERY NEW SD300 130113-00035 Plate, Friction is a dedicated transmission system component for DOOSAN SD300 crawler excavators (heavy-duty equipment for mining, large-scale construction, and bulk material handling). As a key part of the excavator’s clutch or brake mechanism, it generates stable friction force to control power transmission and braking during tasks like heavy ore loading, rock breaking, and slope excavation—ensuring smooth speed adjustment and safe stopping.
   Meeting DOOSAN OEM standards (part no. 130113-00035), it endures high friction temperatures (up to 280°C), resists wear and oil contamination, and maintains consistent friction coefficient. Strict performance testing guarantees seamless compatibility and long-term reliable operation for DOOSAN SD300.
