SPARKLING ZGAQ-02176 Casing – Durable Excavator Part

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.

   The 31QB-12370 Engine Block is a premium cast-iron cylinder block, the core structural foundation for Hyundai R480LC-9, R480LC-9A, R480LC-9S crawler excavators (fitted with Scania DC13 engine). It houses cylinders, crankshaft, and camshaft, integrates coolant/oil passages, and ensures precise component alignment for efficient combustion and power delivery. 

Key Features
· OEM-Matched Precision: 6-cylinder inline design, 12.7L displacement, exact mounting dimensions for Hyundai R480LC-9 series—no modification needed.
· High-Strength Cast Iron: HT300 cast iron construction with normalized heat treatment (HB 200–230) for maximum durability and wear resistance.
· Leak-Proof & Heat-Resistant: Precision-machined deck surface, integrated core plugs, and nitrile rubber seals prevent oil/coolant leakage; withstands 180°C max operating temperature.
· Plug-and-Play Installation: Pre-drilled mounting holes, factory-fitted cylinder liners, and camshaft bearings reduce replacement time to 8–10 hours.

Compatible Models: This block is primarily used in the 9-Series Hyundai crawler excavators from a specific serial number range onwards (S/N 0203 ~)：
· R480LC9, R480LC9A, R480LC9S, R520LC9, R520LC9A, and R520LC9S.
· Interchangeable Part Numbers: 31QB-12370, 31QB12370, 31QB-12370X.

   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.

   SPARKLING MACHINERY NEW XS163 803004248 Gear Pump is a core hydraulic auxiliary component exclusively for XCMG XS163 excavators (heavy-duty construction/mining use). It delivers steady low-to-medium pressure hydraulic fluid to power auxiliary systems like steering and lubrication. 
   Meeting XCMG OEM standards (803004248), it resists -30°C to 100°C temps, wear, and pressure, ensuring seamless compatibility and long-term reliable fluid supply performance.
