The 31QB-10037 / 31QB-10030 Hydraulic Main Pump Assembly is an essential component for delivering stable hydraulic power to your Hyundai crawler excavators. Built for high-performance, this pump guarantees powerful flow, high efficiency, and exceptional durability even under extreme excavation workloads.

🔧 Key Features:

• Original quality fitment for Hyundai’s large crawler excavators

• Ensures precise pressure regulation and smooth hydraulic operation

• Manufactured with high-grade wear-resistant components

• Rigorously tested for flow rate, pressure endurance, and temperature resilience

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 R320LC9 R330LC9A R330LC9S 31Q9-19140 Swing Reduction Gear is a premium China-made transmission component specifically engineered for R320LC9, R330LC9A, and R330LC9S excavators. As a critical part of the swing system, it converts high-speed, low-torque input into low-speed, high-torque output, enabling smooth and controlled rotation of the upper structure (boom, arm, and bucket) during precision positioning, material handling, and heavy-duty operations.

   Designed to original equipment standards, it maintains stable power transmission and efficient torque conversion even under continuous rotational stress and heavy loads. With optimized gear meshing design for minimal friction and noise, it adapts seamlessly to harsh working environments, from construction sites to mining areas. Backed by strict quality verification, it guarantees consistent performance to support uninterrupted machinery operation.

   SPARKLING MACHINERY NEW EC140C EC140D EC160C EC160E 14534865 Seal Kit is a dedicated, all-in-one sealing solution exclusively engineered for VOLVO EC140C, EC140D, EC160C, and EC160E excavators—core equipment in construction, mining, and large-scale infrastructure projects. As a critical protective component for the excavators’ hydraulic systems, it covers key areas such as hydraulic cylinder rods, valve connections, and pump interfaces, forming robust leakproof barriers. This function is vital for maintaining stable hydraulic pressure, ensuring smooth and responsive operation of core mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust or debris from contaminating internal hydraulic parts. It directly reduces the risk of hydraulic system failures, avoids unplanned downtime, and eliminates costly repairs caused by oil leaks during high-intensity tasks like deep excavation, bulk material loading, and site grading.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 36 MPa), extreme temperature fluctuations (-25°C to 105°C), and continuous excavator vibration. It resists oil aging and material wear, providing long-lasting protection for the excavators’ hydraulic systems. Backed by strict performance verification, it guarantees uninterrupted sealing support for EC140C/EC140D/EC160C/EC160E excavators.
