SPARKLING Excavator Steering Components

The Tie Rod Axle is a critical component for the steering system of wheel excavators such as R210W-9, R200W-7, and R200W-7A. This part ensures precise control, alignment stability, and smooth directional changes — all essential for safe and efficient machine operation.

Our tie rod axles — including parts ZGAQ-03225, 0501.007.717, K9007265, K9004062, ZGAQ-04985, and ZGAQ-04480 — are manufactured to OEM specifications, providing excellent durability, corrosion resistance, and compatibility with major wheel excavator models. These components are precision-engineered to handle the high loads and vibrations typical in heavy-duty construction applications.

   SPARKLING MACHINERY NEW ND116140-0050 Heater Core is a core climate control component for Komatsu PC130/PC300/PC350/PC400 excavators (construction/mining use). It heats cabin air via engine coolant circulation, delivering consistent warmth to ensure comfortable and safe operation in low temperatures. 
   Meeting Komatsu OEM standards (ND116140-0050), it resists -30°C to 120°C temps, corrosion, and coolant contamination, guaranteeing seamless compatibility and reliable long-term heating performance.

   SPARKLING MACHINERY NEW CX460 CX470B CX470C LJ00981 Main Relief Valve is a dedicated, high-pressure hydraulic safety component exclusively engineered for CASE CX460, CX470B, and CX470C crawler excavators—heavy-duty equipment widely used in large-scale construction, mining, and quarrying projects. As the core safety guard of the excavator’s hydraulic system, it precisely controls and limits maximum hydraulic pressure (preventing exceeding safe thresholds), protecting critical components like hydraulic pumps, cylinders, and pipelines from damage caused by pressure spikes. This function is vital for maintaining stable hydraulic performance during high-intensity tasks (e.g., rock breaking, bulk ore loading) and avoiding costly downtime from hydraulic system failures.

   Engineered to meet CASE’s original equipment (OEM) standards and marked with the genuine part number LJ00981, the main relief valve withstands harsh working conditions: high operating pressure (up to 38 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous vibration from heavy-duty use. It resists oil contamination and mechanical wear, ensuring long-lasting pressure regulation reliability for the three CASE excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.

   SPARKLING MACHINERY NEW R290LC7A RD340LC-7 39Q8-42100 39Q8-42102 Travel Reduction Gear is a premium China-made transmission component specifically engineered for R290LC7A and RD340LC-7 excavators. As a critical part of the travel system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling steady and powerful movement across diverse job sites, from rough terrain to heavy-load operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous operational stress and uneven ground conditions. With optimized gear meshing design for minimal wear and energy loss, it adapts seamlessly to harsh working environments, from construction zones to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.
