ZF 4699.172.023 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.023 STEERING PARTS component is a critical OEM genuine part designed for the steering control assembly within heavy-duty construction machinery transmissions. This part functions as a precision-machined interface element, ensuring accurate hydraulic fluid direction to the steering cylinders during operation. Positioned within the valve body section of the transmission, the SKU 4699.172.023 works in concert with the 4699101044: HOUSING and the 4699301111: HOUSING to maintain proper steering response and load control. This genuine ZF part guarantees factory tolerances for long service life in demanding environments like wheel loaders and excavators.

Symptoms of Failure

• Erratic steering response or delayed hydraulic reaction — When the 4699.172.023 wears, operators may notice a lag between steering input and machine movement, often accompanied by spongy or inconsistent feel.
• External hydraulic fluid seepage around the steering housing — Degraded sealing surfaces on this part can cause visible oil leaks near the 4699301054: HOUSING COVER and 4699301055: COVER, leading to fluid loss and contamination.
• Increased steering effort or jerky movements — Internal wear of the steering parts can cause uneven pressure distribution, resulting in hard steering or sudden lurching during turns.
• Unusual whining or grinding noises from the steering assembly — Metal-to-metal contact from a failing 4699.172.023 often produces audible sounds, especially during low-speed maneuvers.

Technical Specifications

Compatibility

This steering part is primarily compatible with ZF WG180 and WG200 series transmissions commonly found in construction machinery such as wheel loaders, telehandlers, and compact excavators. It also fits select ZF 4WG-180 and 4WG-200 models where steering control valves utilize the 4699.172.023 geometry. For precise fitment, always verify the transmission serial number against OEM documentation. The part integrates directly with the 4699101044: HOUSING and 4699301111: HOUSING assemblies.
