SPARKLING Pump Coupler for CAT Excavators – Durable & Reliable

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's new 23527829 Sensor is a core detection component specifically designed for Volvo excavators, suitable for construction and mining applications. It accurately collects and transmits key operational data (e.g., pressure, temperature, position) to the control system, ensuring precise equipment operation. 
   Compliant with Volvo OEM standards (Part No.: 23527829), this component exhibits excellent detection accuracy and signal stability, ensuring seamless compatibility with original equipment and long-term reliable operational performance.

   SPARKLING MACHINERY NEW 14704262 Center Swivel Joint is a premium China-made hydraulic connection component designed for compatible excavators. As a critical link between the excavator’s fixed lower structure (undercarriage) and rotating upper structure (cabin, boom, and working arms), it enables uninterrupted 360° rotation while maintaining seamless hydraulic fluid transmission to core systems—including swing motors, hydraulic cylinders, and control valves. This ensures consistent power delivery for essential operations like digging, lifting, and precision swing movements in construction, mining, and earthmoving tasks.

   Engineered to original equipment standards, it maintains leak-free performance even under high hydraulic pressure (up to industry-standard thresholds) and continuous rotational stress, as well as harsh working conditions such as dust, vibration, and exposure to construction debris or moisture. With optimized high-wear-resistance sealing rings and precision-machined internal flow channels, it minimizes pressure loss and prevents fluid contamination, protecting the hydraulic system from damage. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted machinery rotation and maximize work efficiency.

   SPARKLING MACHINERY NEW 31N7-50132 Arm Cylinder is a core hydraulic actuator for Hyundai R250/260 excavator models (heavy-duty construction/mining use). It delivers stable, high torque for arm lifting, lowering, and precision positioning, critical for heavy-load operations. 
   Meeting Hyundai OEM standards (31N7-50132), it resists -30°C to 100°C temps, high hydraulic pressure, and wear, ensuring seamless compatibility and long-term reliable arm control performance.
