SPARKLING CAT 312D Swing Gearbox – Durable Excavator Part

The Caterpillar Swing Reducer (Part No. 333‑3073 / 3333073) is a premium swing gearbox designed to restore smooth and powerful 360° rotation in CAT excavators—compatible with 312D, 312DL, 312D2, 312E, 313D, 313D2, 314C, and 314E models. 

It features hardened steel planetary gears, sealed bearings, and robust housing to handle heavy-duty rotational loads while preventing leaks and contamination . Available as genuine OEM or high-quality aftermarket units, this swing reducer ensures a direct-fit replacement and optimized machine performance.

   SPARKLING MACHINERY NEW EC380D VOE14684117 Relief Valve is a dedicated hydraulic pressure protection component for Volvo EC380D crawler excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "safety core" of the hydraulic system, it automatically relieves excess pressure when it exceeds the set threshold—preventing damage to pumps, cylinders, and hoses during high-intensity tasks like heavy digging, rock breaking, and bulk material lifting.
   Meeting Volvo OEM standards (part no. VOE14684117), it maintains a precise pressure range of 30-34 MPa, endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and ensures instant pressure relief response. Strict testing guarantees seamless compatibility with Volvo EC380D and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW EX33MU ZX27-3 ZX30 ZX35 4373411 Oil Cooler is a dedicated thermal management component exclusively designed for EX33MU, ZX27-3, ZX30, and ZX35 mini excavators. As a core part of these machines’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during tasks like urban construction, agricultural tillage, and small-scale mining. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of EX33MU/ZX-series mini excavators.

   Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous machine vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of target mini excavators.

The XKCH-00022 Solenoid Valve is a precision-engineered hydraulic control component used in multiple Hyundai crawler excavators, including models R125LCR-9A, R145CR9, R160LC9A, and R180LC9S.

This solenoid valve plays a vital role in directing hydraulic fluid flow in key systems such as travel, swing, or attachment control. Engineered for responsive performance and long-lasting durability, this part ensures accurate actuation and helps maintain overall machine efficiency.
