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.

   SPARKLING MACHINERY NEW R290LC7A 110D-7E R210LC9 XKDE-01492 Tensioner is a dedicated drive system component exclusively designed for R290LC7A, 110D-7E, and R210LC9 excavators. As a core part of the excavators’ belt-driven systems (powering critical accessories like alternators, water pumps, and air compressors), it automatically maintains optimal tension in drive belts. This key function prevents belt slippage (which leads to inefficient power transmission and accessory overheating) and reduces excessive belt wear, ensuring consistent operation of essential engine auxiliary systems during heavy-duty tasks such as digging, lifting, and earthmoving.

   Engineered to match original equipment performance standards, it adapts seamlessly to dynamic working conditions—including intense vibration, temperature fluctuations, and natural belt stretch over time—without the need for manual adjustments. It safeguards the belt drive system from damage caused by loose or over-tightened belts, minimizing unplanned downtime and supporting uninterrupted excavator operation. Backed by strict performance verification, it guarantees long-term reliability for the drive system.

   The HIGH-QUALITY 6138-42-1010 CAMSHAFT is a premium engine control component meticulously engineered for Komatsu Construction Equipment, specifically tailored to meet the precision timing and durability demands of S6D110, SA6D110, and S6D105 excavators. As a core part of the engine’s valve train system, this camshaft regulates the opening and closing of intake and exhaust valves with precise timing, ensuring optimal air-fuel mixture intake, efficient exhaust emission, and synchronized engine operation—even during prolonged heavy-duty construction tasks. 
   Designed to seamlessly integrate with Komatsu’s engine architecture, it delivers consistent performance that enhances the excavator’s power output, fuel efficiency, and overall operational reliability.
