SPARKLING Doosan Steering Pump – Durable Hydraulic Solution

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 EC350E EC380EHR 14508626 Wiper Relay is a key electrical control component for Volvo EC350E and EC380EHR excavators (widely used in heavy construction, mining, and infrastructure projects). As the "wiper operation controller", it regulates power supply to the excavator’s windshield wiper system—enabling smooth wiper activation, speed adjustment, and shutdown during rainy, snowy, or dusty conditions. This ensures clear visibility for operators during tasks like digging, lifting, and rock breaking, while preventing wiper motor damage from electrical overloads.
   Meeting Volvo OEM standards (part no. 14508626), it endures -30°C to 85°C temperatures, resists moisture and vibration, and guarantees stable electrical switching. Strict testing ensures seamless compatibility with the two Volvo models and long-term reliability of the wiper system.

   SPARKLING MACHINERY NEW EX270 EX270-5 EX280H-5 EX300 EX300-2 EX300-3 4067720 Bushing is a critical wear-resistant component for Hitachi EX270, EX270-5, EX280H-5, EX300, EX300-2, and EX300-3 excavators (widely used in construction, mining, and earthmoving projects). As the "joint buffer", it reduces friction between moving parts (e.g., boom hinges, arm connections) during tasks like digging, lifting, and swing operations—preventing metal-to-metal wear, absorbing vibration, and ensuring smooth movement of hydraulic structures.
   Meeting Hitachi OEM standards (part no. 4067720), it endures -30°C to 100°C working temperatures, resists corrosion and impact, and maintains stable dimensional accuracy. Strict testing guarantees seamless compatibility with the six Hitachi models and long-term reliability of excavator structural joints.

   SPARKLING MACHINERY NEW 306E 307E 308E 423-4562 Solenoid Assy is a dedicated electrical control component for Caterpillar 306E, 307E, and 308E mini crawler excavators (versatile for landscaping, indoor demolition, and small-scale construction). As a key part of the excavator’s hydraulic or fuel system, it integrates solenoid and accessory components to convert electrical signals into mechanical action—controlling valve actuation or fuel flow to ensure precise operation of functions like bucket tilting and arm movement during delicate tasks.
   Meeting Caterpillar OEM standards (part no. 423-4562), it endures -30°C to 85°C temperatures, resists vibration and electrical interference, and maintains stable switching performance. Strict testing guarantees seamless compatibility and long-term reliability for the three Caterpillar models.
