SPARKLING Track-Type Tractor Valve – Durable & Precise Excavator Parts

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 334/C2149 Oil Cooler is a dedicated thermal management component designed for compatible heavy-duty construction machinery, such as excavators and loaders. As a core part of the machinery’s hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during high-intensity operations like deep digging, heavy-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (e.g., hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable machinery power output and extending overall service life.

   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 constant machinery 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 compatible heavy-duty machinery.

   SPARKLING MACHINERY NEW X220571211 Radiator is a critical cooling system component designed for compatible construction machinery, including excavators and loaders. As the core of the machinery’s heat dissipation system, it efficiently cools engine coolant by transferring heat from the coolant to the surrounding air—preventing engine overheating during heavy-duty operations like prolonged digging, high-load lifting, and continuous idling in construction, mining, or infrastructure projects. This function is essential for maintaining the engine’s optimal operating temperature, which directly impacts fuel efficiency, power output, and long-term service life.
