SPARKLING PC70-7 Swing Gear Reducer – Durable & Precise 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.

The Caterpillar Coupling-Pump (Part No. 267-1082 / CA2671082 / 2671082) is a high-quality aftermarket replacement part made in China, engineered to fit CAT mini hydraulic excavators such as 305C CR, 305.5E, and certain Caterpillar wheel loader models.

This coupling serves as a crucial link between the engine and hydraulic pump, ensuring efficient power transmission while absorbing vibration and reducing stress on connected components. Built from durable elastomeric and metal materials, it offers excellent torsional flexibility and resistance to wear — helping maintain optimal machine performance.

If you're looking for a cost-effective yet reliable alternative to OEM parts, this China-made coupling is a smart choice for equipment maintenance and repair, without compromising functional integrity.

   SPARKLING MACHINERY NEW A25D EC140C EC240C EW40D 960254 O-Ring is a dedicated sealing component exclusively engineered for VOLVO A25D articulated dump trucks, EC140C/EC240C excavators, and EW40D wheeled excavators—key equipment in construction, mining, and municipal infrastructure projects. As a critical part of the machinery’s hydraulic, fuel, and coolant systems, it creates tight, leakproof seals between mating components (e.g., hydraulic valve connections, fuel line joints, and coolant hoses). This function is essential for maintaining system pressure stability, preventing fluid leakage (hydraulic oil, fuel, coolant), and blocking dust or debris from entering internal mechanisms. It directly reduces the risk of system failures, avoids unplanned downtime, and eliminates costly repairs caused by leaks during high-intensity operations like heavy hauling, digging, or road maintenance.

   Engineered to match VOLVO’s original equipment standards, the O-ring maintains reliable sealing performance even under harsh conditions: high pressure (up to 32 MPa), extreme temperature fluctuations (-30°C to 110°C), and continuous machinery vibration. It resists fluid aging and material degradation, ensuring long-lasting protection for VOLVO A25D/EC140C/EC240C/EW40D systems. Backed by strict performance verification, it guarantees consistent sealing support for these VOLVO models.

The 709-63-11501 / 709-63-11600 Control Valve Assembly is a precision-engineered hydraulic component specifically designed for Komatsu D375A series bulldozers. As a key part of the machine’s hydraulic system, this valve ensures smooth, accurate, and responsive blade and ripper control—essential for productivity in high-demand mining, earthmoving, and large-scale construction environments.

Manufactured with robust materials and OEM-level quality control, our replacement control valve delivers stable pressure regulation, excellent sealing performance, and long service life, even under continuous heavy-duty operation.
