SPARKLING EC140D Switch - Reliable Excavator Electrical Component

   SPARKLING MACHINERY NEW 336GC 340GC 345GC 350GC 510-1695/617-1905 Injector is a core engine fuel injection component for Caterpillar 336GC, 340GC, 345GC, and 350GC excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "fuel atomization core", it precisely sprays fuel into the combustion chamber—ensuring efficient fuel combustion during high-intensity tasks like rock breaking, deep digging, and heavy lifting, while maintaining stable engine power output and reducing fuel waste.
   Meeting Caterpillar OEM standards (part nos. 510-1695/617-1905), it endures -30°C to 200°C engine temperatures, resists fuel corrosion and vibration, and guarantees consistent injection pressure. Strict testing ensures seamless compatibility with the four Caterpillar models and long-term engine reliability.

Part number ZGAQ-03591 refers to a Hub-Axle (also known as a front or rear axle hub) used in Hyundai wheeled excavators.

Part Name: Hub-Axle / HUB, FR AXLE / Axle Hub.
Function: A structural component of the excavator's axle that the wheel mounts onto, crucial for the vehicle's mobility.
Weight: Approximately 34 kg (75 lbs).
Compatibility: Designed specifically for Hyundai R-series wheeled excavators.

The ZGAQ-03591 axle hub is used on various Hyundai wheeled excavator models, typically within the 7-Series and 9-Series ranges: 
R160W-9A
R170W-7 and R170W-7A
R170W-9 and R170W-9S
R180W-9A and R180W-9S
R210W-9 

   SPARKLING MACHINERY NEW DX340LC 404-00094A Swing Reduction Gear is a core transmission component exclusively for Doosan DX340LC excavators (heavy-duty construction/mining use). It reduces engine speed to deliver high torque for smooth, precise upper-structure rotation. 
   Meeting Doosan OEM standards (404-00094A), it resists -30°C to 100°C temps, wear, and impact, ensuring seamless compatibility and long-term reliable swing performance.

   SPARKLING MACHINERY NEW R170W7 R170W7A R170W9S ZGAQ-02283 Cylinder-Steering is a premium China-made hydraulic component specifically engineered for R170W7, R170W7A, and R170W9S wheel excavators. As a critical part of the steering system, it converts hydraulic pressure into linear motion to enable smooth and precise directional control, ensuring stable maneuvering during operation, positioning, and job site navigation.

   Designed to original equipment standards, it maintains consistent force output and responsive operation even under heavy loads and continuous use. With optimized seal design for leak resistance and robust structural integrity, it adapts seamlessly to harsh working environments, from muddy construction sites to rough terrain. Backed by strict quality verification, it guarantees reliable performance to support safe and uninterrupted machinery operation.
