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 R290LC7A 110D-7E R210LC9 XKDE-01492 Tensioner is a dedicated drive system component exclusively designed for R290LC7A, 110D-7E, and R210LC9 excavators. As a core part of the excavators’ belt-driven systems (powering critical accessories like alternators, water pumps, and air compressors), it automatically maintains optimal tension in drive belts. This key function prevents belt slippage (which leads to inefficient power transmission and accessory overheating) and reduces excessive belt wear, ensuring consistent operation of essential engine auxiliary systems during heavy-duty tasks such as digging, lifting, and earthmoving.

   Engineered to match original equipment performance standards, it adapts seamlessly to dynamic working conditions—including intense vibration, temperature fluctuations, and natural belt stretch over time—without the need for manual adjustments. It safeguards the belt drive system from damage caused by loose or over-tightened belts, minimizing unplanned downtime and supporting uninterrupted excavator operation. Backed by strict performance verification, it guarantees long-term reliability for the drive system.

The ZF 4472397017 Bearing Pin (also known as 4472.397.017 or 4472-397-017) is a vital component engineered for use in ZF axle and transmission systems. It plays a key role in maintaining proper alignment and reducing friction between moving parts, ensuring the smooth and efficient operation of your machinery.

Manufactured to OEM specifications, this bearing pin is constructed from hardened, corrosion-resistant steel for enhanced strength and long-term durability in harsh working environments. It is an ideal solution for equipment requiring high-reliability replacement parts to minimize downtime and maintenance costs.
