SPARKLING CAT Original Valve – High-Quality 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 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.

   SPARKLING MACHINERY NEW 432E 434E 442E 444E 289-6370 Pump GP-Piston is a core hydraulic power component for Caterpillar 432E/434E/442E/444E excavators (heavy-duty construction/mining use). It delivers high-pressure, variable-displacement hydraulic fluid to drive critical systems like arms and travel mechanisms. 
   Meeting Caterpillar OEM standards (289-6370), it resists -30°C to 100°C temps, high pressure, and wear, ensuring seamless compatibility and long-term reliable power supply.

   The HIGH-QUALITY 6138-31-3104 Connecting Rod Assembly is a premium powertrain component meticulously engineered for Komatsu Construction Equipment, specifically tailored to meet the high-torque and durability demands of S6D110 and SA6D110 excavators. As a critical link between the engine’s piston and crankshaft, this connecting rod assembly transmits linear piston motion into rotational crankshaft power, ensuring efficient energy transfer and stable 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, operational reliability, and service life.
