SPARKLING PC60-7 Swing Gearbox – Reliable Excavator Part

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 VOE14598751 Swing Motor, a high-quality China-made core hydraulic component for excavators, is engineered to deliver reliable rotational power for smooth 360° slewing of the upper structure. Built to original equipment standards, it ensures seamless compatibility with compatible excavator models, making it an ideal replacement part for construction, mining, and earthmoving operations.

   Crafted from high-strength alloy materials with precision-machined internal components, this swing motor withstands high pressure and heavy loads while maintaining stable performance. Equipped with advanced hydraulic control technology and multi-layer sealing systems, it achieves excellent resistance to dust, water, and leakage, adapting to harsh working environments. Backed by strict quality testing and professional technical support, it guarantees long-term operational efficiency, minimizing downtime and maximizing equipment productivity.

   SPARKLING MACHINERY NEW EC700CHR EC750D EC750E EC950E VOE14625689 Venting is a key pressure regulation component for 4 large Volvo excavator models (mining/heavy construction use). It balances internal pressure in systems (e.g., fuel tanks, hydraulic reservoirs) to prevent leaks or component damage, ensuring stable operation. 
   Meeting Volvo OEM standards (VOE14625689), it resists -30°C to 100°C temps, dust, and moisture, guaranteeing seamless compatibility and long-term reliable pressure control.

   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.
