SPARKLING Komatsu Excavator Parts – Precision & Reliability

The JCB Swing Gearbox Assembly (suitable for JS70, PC60‑7, and PC70‑7/PC60‑7 excavators) is a precision-engineered swing reducer designed to deliver smooth and reliable rotational performance. Built to OEM standards (e.g., part no. LNM0639 / 201-26‑00130), this gearbox features hardened steel gears and robust bearings—ensuring durable operation under heavy load. It’s designed for easy drop-in replacement and reduces maintenance downtime. Ideal for construction, demolition, and excavation applications.

   SPARKLING MACHINERY NEW R360LC7A 21NA-34100 Controller is a dedicated electronic control unit for Hyundai R360LC7A crawler excavators (widely used in construction, mining, and large-scale infrastructure projects). As the "brain" of the excavator, it processes real-time data from sensors (e.g., engine, hydraulic, and operator controls) to regulate key functions—such as engine speed, hydraulic flow, and bucket operation—ensuring coordinated, efficient performance during high-intensity tasks like heavy digging and rock breaking.
   Meeting Hyundai OEM standards (part no. 21NA-34100), it endures -30°C to 85°C temperatures, resists electromagnetic interference and vibration, and maintains stable data transmission. Strict testing guarantees seamless compatibility with Hyundai R360LC7A and long-term reliable equipment control.

   SPARKLING MACHINERY NEW EC120D EC140B EC140C VOE14649606 Compressor is a premium China-made climate control component specifically engineered for EC120D, EC140B, and EC140C excavators. As a key part of the cabin cooling system, it compresses refrigerant to maintain optimal temperature regulation, ensuring operator comfort and productivity in extreme weather conditions—from scorching construction sites to humid industrial zones.

   Designed to original equipment standards, it delivers consistent cooling performance with stable pressure output even under prolonged operation. With optimized structural design for minimal vibration and energy consumption, it integrates seamlessly into the machinery’s existing climate system. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted work cycles in harsh environments.

   SPARKLING MACHINERY NEW PC45MR PC55MR 708-3S-04571 Gear Pump is a dedicated hydraulic power supply component for Komatsu PC45MR and PC55MR mini crawler excavators (widely used in urban construction, garden maintenance, and narrow-space earthmoving). As the "hydraulic power source", it converts engine mechanical energy into hydraulic pressure—supplying stable high-pressure oil to cylinders, valves, and actuators for tasks like small-scale digging, material loading, and landscape trimming, while ensuring responsive and efficient equipment operation.
   Meeting Komatsu OEM standards (part no. 708-3S-04571), it maintains a rated pressure of 25 MPa, endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees low-noise, leak-free performance. Strict testing ensures seamless compatibility with Komatsu PC45MR/PC55MR and long-term hydraulic system reliability.
