SPARKLING JCB Swing Reducer – Reliable Excavator Component

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.

The VOE14683841 Seal Kit from SPARKLING MACHINERY is designed for Volvo EC220D, EC220E, and EC235D excavators. Made from high-quality rubber, PU, and PTFE, it ensures reliable sealing, wear resistance, and easy installation—ideal for hydraulic cylinder maintenance with OEM-level performance.

   SPARKLING MACHINERY NEW 6675-31-1011 Crankshaft is a critical power transmission component tailor-made for compatible heavy-duty diesel engines used in excavators, loaders, and industrial machinery. As the "rotational core" of the engine, it converts the reciprocating motion of pistons into continuous rotational torque, which drives the machinery’s hydraulic systems, undercarriage, and working mechanisms. This function is essential for delivering consistent power to support heavy-duty tasks like deep digging, large-volume material lifting, and continuous mining operations.

   Designed to meet original equipment performance standards, it maintains stable operation even under extreme conditions—including high rotational speeds, intense mechanical loads, and temperature fluctuations. It ensures smooth torque transfer with minimal vibration, preventing premature wear of engine components and safeguarding long-term operational efficiency. Backed by strict performance verification, it guarantees reliable power output to minimize engine downtime and keep heavy machinery running continuously.

   SPARKLING MACHINERY NEW R110-7 R140LC-7 R140W7 R210LC7H 21EN-32260 Accel Actuator is a dedicated electronic control component for Hyundai R110-7, R140LC-7, R140W7, and R210LC7H crawler excavators (widely used in construction, municipal engineering, and medium-scale earthmoving). As a core link between the operator’s accelerator input and the engine, it converts electrical signals into mechanical actions to adjust engine speed—ensuring responsive, precise power output during tasks like digging, loading, and slope trimming.
   Meeting Hyundai OEM standards (part no. 21EN-32260), it endures -30°C to 85°C temperatures, resists electromagnetic interference and vibration, and maintains stable signal transmission. Strict testing guarantees seamless compatibility with the four Hyundai models and long-term reliable engine speed control.
