SPARKLING Caterpillar Manual Valve – Reliable Excavator Hydraulic Control

The Valve GP‑Manual (Cat part no. 389‑2407 / CA3892407) is a rugged manual auxiliary shut‑off valve designed for use in heavy-duty Caterpillar excavators—specifically models 352, 323F, 320C, 320D SA, M325D MH/L, 355, and more. It provides dependable two-way hydraulic shut-off control, helping protect critical systems during maintenance or attachments handling. Built to OEM tolerance, this valve ensures reliable operation in the harshest environments, available both as a genuine Cat part and high-quality aftermarket alternative.

   SPARKLING MACHINERY NEW R320LC9 R330LC9A R330LC9S 31Q9-19140 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R320LC9, R330LC9A, and R330LC9S excavators. As a critical part of the swing system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

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 EC480D EC380D EC300D EC250D EC220D VOE14725313 Sensor is a dedicated electronic detection component for Volvo EC480D, EC380D, EC300D, EC250D, and EC220D crawler excavators (widely used in heavy construction, mining, and large-scale infrastructure projects). As the "operational data hub" of the excavator, it collects real-time data (e.g., hydraulic pressure, engine temperature, and component position) and transmits it to the control unit—enabling precise adjustment of key functions like heavy digging, rock breaking, and boom lifting, while ensuring early warning of potential system issues.
   Meeting Volvo OEM standards (part no. VOE14725313), it achieves a detection accuracy of ±0.3%, endures -30°C to 85°C temperatures, resists dust and vibration, and maintains stable signal transmission. Strict testing guarantees seamless compatibility with the five Volvo models and long-term equipment monitoring reliability.
