401-00423 OEM Hydraulic Part

The 401-00423 hydraulic pilot pump, also known as the steering pump or pilot pressure pump, is a key component of the MEGA 500-V TIER-II wheel loader’s hydraulic system. With a robust 45kg build, this high-performance pump ensures precise pilot control, smooth steering assistance, and reliable hydraulic pressure for various operations.

Designed to OEM standards, this pump is built with reinforced cast iron housing, high-efficiency rotors, and hardened shafts, offering excellent resistance to wear, pressure fatigue, and oil contamination. It’s an ideal replacement for the original Doosan/Daewoo system pump and fully compatible with heavy-duty operation demands.

   SPARKLING MACHINERY NEW EC120D EC135B EC140B EC140C EC140D 14591545 Pressure Switch is a key hydraulic safety component for Volvo EC120D, EC135B, EC140B, EC140C, and EC140D excavators (widely used in construction, municipal engineering, and light mining). As the "hydraulic pressure sentinel", it real-time monitors pressure changes in hydraulic circuits—automatically triggering alerts or protective actions via the excavator’s control unit when pressure goes beyond safe limits. This prevents overpressure damage to pumps, valves, and cylinders during tasks like digging or boom lifting, while ensuring stable operation by avoiding underpressure-related function failures.
   Meeting Volvo OEM standards (part no. 14591545), it endures -30°C to 95°C temperatures, resists hydraulic oil corrosion and vibration, and guarantees precise pressure sensing. Strict testing ensures seamless compatibility with the five Volvo models and long-term hydraulic system safety.

   SPARKLING MACHINERY NEW R300LC9S R330LC9S XKDE-00529 Water Pump is a premium China-made cooling system component specifically engineered for R300LC9S and R330LC9S excavators. As a core part of the machinery’s engine cooling system, it circulates coolant between the engine block and radiator to dissipate excess heat generated during heavy-duty operations—such as prolonged digging, high-load lifting, and continuous mining tasks. This ensures the engine maintains an optimal operating temperature, preventing overheating-related damage and safeguarding consistent performance.

   Designed to original equipment standards, it delivers stable coolant flow rates even under extreme working conditions, including high ambient temperatures, dust, and vibration. With optimized impeller design for efficient fluid circulation and a robust sealing structure to prevent coolant leakage, it integrates seamlessly into the excavator’s cooling system. Backed by strict quality verification, it guarantees reliable operation to support uninterrupted machinery work cycles and extend engine service life.

The YA00000734 Control Valve is a genuine and high-performance hydraulic component specifically engineered for use in Hitachi excavator models including ZX330-5G, ZX330LC-5G, ZX350H-5G, ZX350K-5G, ZX350LCH-5G, and ZX350LCK-5G.
Built to OEM specifications, this valve ensures precise fluid control, reliable operation, and extended service life under the toughest working conditions.
Manufactured with original-grade materials, it guarantees a perfect fit and exceptional compatibility with your Hitachi machinery.
