   SPARKLING MACHINERY NEW EC135B EC140B VOE21547101 Cable Harness is a core electrical connection component for 2 Volvo excavator models (construction/municipal use). It transmits stable electrical signals and power between key systems (e.g., control unit, sensors, actuators), ensuring seamless equipment operation. 
   Meeting Volvo OEM standards (VOE21547101), it resists -30°C to 85°C temps, moisture, and abrasion, guaranteeing compatibility with EC135B/EC140B and long-term reliable signal/power transfer.

   SPARKLING MACHINERY NEW ZGAQ-01117 Taper Roller Bearing is a core rotating component for Hyundai HW210/R170W9/R200W7/R200W7A excavators (construction/mining use). It supports radial and axial loads simultaneously, ensuring smooth rotation of key parts like shafts. 
   Meeting Hyundai OEM standards (Part No.: ZGAQ-01117), it features high wear resistance and load-bearing capacity, guaranteeing seamless compatibility and reliable long-term operational performance.

   SPARKLING MACHINERY NEW 320D 323D 324D 325D 329D 165-7065 Radiator is a dedicated, high-efficiency cooling component exclusively engineered for CATERPILLAR 320D, 323D, 324D, 325D, and 329D crawler excavators—heavy-duty equipment widely used in construction, mining, and large-scale infrastructure projects. As the core of the excavator’s engine cooling system, it efficiently dissipates heat from the engine coolant, maintaining optimal operating temperatures (82-95°C) even during prolonged high-intensity tasks like rock breaking, bulk material loading, and deep excavation. This function is vital for preventing engine overheating, avoiding power loss or permanent engine damage, and ensuring uninterrupted workflow for critical projects.

   Engineered to meet CATERPILLAR’s original equipment (OEM) standards and marked with the genuine part number 165-7065, the radiator withstands harsh working conditions: extreme temperature fluctuations (-30°C to 110°C), high coolant pressure (up to 150 kPa), and continuous vibration from heavy-duty use. It resists corrosion, dust accumulation, and coolant leakage, providing long-lasting cooling reliability for the five CATERPILLAR excavator models. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for daily high-load tasks.
