SPARKLING DH300-5 Parts – Durable Excavator Components

The Oil Cooler Assembly (Part No. 13C30000-2 / 13C300002) is specially engineered for Doosan and Daewoo excavator models S290LL, S290LC-V, and DH300-5. Designed to deliver efficient heat dissipation, this oil cooler helps maintain optimal hydraulic oil temperature, thereby enhancing the longevity and performance of your machinery.

Manufactured with high-strength aluminum and precision-welded construction, this oil cooler offers excellent thermal conductivity, durability, and resistance to vibration—ideal for demanding construction and forestry environments.

The 558-5127 / 5585127 Valve GP-QDR is a genuine replacement hydraulic control valve designed for CAT D7 Track-Type Tractors. Manufactured to Caterpillar OEM standards and weighing 27KG, this original valve ensures high precision fluid control in demanding construction and earthmoving environments.

As a critical component in the hydraulic control system, the GP-QDR valve regulates the flow and pressure to various functions of the bulldozer, helping to deliver reliable and responsive operational performance. SPARKLING MACHINERY offers this valve as part of our premium product lineup—ideal for equipment owners seeking both authenticity and performance assurance.

   SPARKLING MACHINERY NEW R80-7 R80-7A 11N1-42120 Oil Cooler is a dedicated thermal management component exclusively designed for R80-7 and R80-7A excavators. As a core part of these excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during tasks like small-scale construction, agricultural tillage, and urban 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 R80-7/R80-7A excavators.

   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 R80-7 and R80-7A excavators.

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.
