SPARKLING 5585127 GP-QDR Valve – Reliable Excavator Hydraulic Component

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 EC460B EC460C EC480D EC480E 14589145 Seal Kit is a dedicated, heavy-duty sealing solution exclusively designed for VOLVO EC460B, EC460C, EC480D, and EC480E excavators—core equipment in large-scale mining, construction, and infrastructure projects. As a critical protective component for the excavators’ high-pressure 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 high-load mechanisms (boom lifting, arm digging, bucket tilting), and preventing dust, gravel, or moisture 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 rock breaking, bulk material loading, and deep excavation.

   Engineered to meet VOLVO’s original equipment standards, the seal kit maintains reliable sealing performance even under harsh conditions: high hydraulic pressure (up to 40 MPa), extreme temperature fluctuations (-25°C to 110°C), and continuous heavy-duty 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 EC460B/EC460C/EC480D/EC480E excavators.

   SPARKLING MACHINERY NEW SD300 130113-00035 Plate, Friction is a dedicated transmission system component for DOOSAN SD300 crawler excavators (heavy-duty equipment for mining, large-scale construction, and bulk material handling). As a key part of the excavator’s clutch or brake mechanism, it generates stable friction force to control power transmission and braking during tasks like heavy ore loading, rock breaking, and slope excavation—ensuring smooth speed adjustment and safe stopping.
   Meeting DOOSAN OEM standards (part no. 130113-00035), it endures high friction temperatures (up to 280°C), resists wear and oil contamination, and maintains consistent friction coefficient. Strict performance testing guarantees seamless compatibility and long-term reliable operation for DOOSAN SD300.

The Radiator Core (Part No. 22U-03-22113 / 22U-03-22112 / 22U-03-22111) is a high-quality cooling component designed specifically for Komatsu PC228 and PC228US excavators. This core is engineered to maintain optimal engine temperature, ensuring reliable machine performance under extreme working conditions.

Constructed with durable aluminum alloy and efficient heat dissipation fins, this radiator core guarantees excellent thermal performance, corrosion resistance, and long service life. It is a direct-fit replacement, tested to meet or exceed OEM standards.
