SPARKLING Wheel Loader Pilot Pump – Reliable Hydraulic Control

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.

   The VOE14587558 is an OEM-compatible boom hydraulic cylinder, designed as the core actuation component for Volvo EC160C and EC180C excavators. It delivers stable lifting force (32–35 MPa) and precise stroke control for boom, arm, and bucket functions in construction, mining, and infrastructure projects.

Key Features
· Durability: Built to withstand extreme environmental conditions and high-pressure hydraulic fluctuations.
· Precision: Ensures accurate steering response, which is critical for safety and operational efficiency on job sites.
· Ease of Maintenance: Designed for direct fitment, reducing downtime during replacement or overhaul.

Primary Compatibility: Most commonly utilized in Volvo EC160C and EC180C excavators, as well as specific wheel loaders and articulated haulers.
