SPARKLING CAT 305C CR Pump Part – Reliable Excavator Component

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 440211-01543 DX490LC-7M (OEM) Radiator is an exclusive OEM-standard cooling core component designed specifically for DX490LC-7M large excavators—commonly used in heavy mining, large-scale construction, and infrastructure projects. As the core of the excavator’s engine cooling system, it efficiently dissipates excess heat generated by the high-power engine during prolonged heavy-load operations (such as rock breaking, bulk material loading, and deep excavation) by transferring heat from coolant to ambient air. This function is critical for maintaining the engine’s optimal operating temperature (85–95°C), preventing overheating-induced power loss, cylinder head warping, or irreversible engine damage, while ensuring consistent productivity in demanding work environments.

   Engineered to meet 100% OEM specifications, it maintains superior heat dissipation efficiency even under harsh conditions—including high ambient temperatures (up to 50°C), continuous excavator vibration, and exposure to dust, gravel, or heavy rain. It resists coolant leakage and core corrosion, avoiding cooling system failures that lead to costly unplanned downtime. Backed by strict OEM-level performance verification, it guarantees reliable heat management to support uninterrupted operation of DX490LC-7M excavators.

   SPARKLING MACHINERY NEW 320D 320D2 312-8338 Oil Cooler is a dedicated thermal management component exclusively designed for 320D and 320D2 excavators. As a core part of the excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during heavy-duty operations like construction digging, mining loading, and infrastructure maintenance. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of 320D/320D2 machinery.

   Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of 320D and 320D2 excavators.

   SPARKLING MACHINERY NEW EC140B EC160B EC210B EC240B VOE114533206 Coupling Assy 17T is a dedicated, heavy-duty mechanical component exclusively engineered for VOLVO EC140B, EC160B, EC210B, and EC240B crawler excavators—versatile mid-to-large equipment widely used in construction, mining, and infrastructure maintenance projects. As a critical connection part for the excavator’s power transmission system, it links key components (e.g., engine, hydraulic pump) to transfer torque smoothly, ensuring synchronized power delivery to core mechanisms like boom lifting, arm digging, and bucket tilting. This function is vital for maintaining stable operational efficiency during high-intensity tasks such as rock breaking, bulk material loading, and deep excavation, preventing power loss or transmission jolts that could disrupt workflows.

   Engineered to meet VOLVO’s original equipment (OEM) standards and marked with the genuine part number VOE114533206 (featuring a 17-tooth design for precise engagement), the coupling assy withstands harsh working conditions: high torque loads (up to 850 N·m), extreme temperature fluctuations (-25°C to 100°C), and continuous vibration from heavy-duty use. It resists wear, corrosion, and mechanical fatigue, providing long-lasting reliability for the excavators’ power transmission systems. Backed by strict performance verification, it guarantees seamless compatibility and safe operation for EC140B/EC160B/EC210B/EC240B models.
