ZF 4699.172.110 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.110 STEERING PARTS component is a critical OEM genuine part designed for the hydraulic steering circuit within heavy-duty ZF construction machinery transmissions. This precision-engineered assembly manages fluid flow to the steering cylinder, ensuring responsive and reliable directional control under extreme loads. As a direct replacement for worn units, the SKU 4699.172.110 restores factory-spec steering performance. It integrates directly with the main valve body and is commonly installed alongside the 4699005026: GK30 gear kit and the 4699101018: HOUSING to complete the steering control assembly.

Symptoms of Failure

• Erratic steering response or jerky wheel movement – Worn internal seals in the 4699.172.110 cause inconsistent hydraulic pressure, making the machine difficult to control during low-speed maneuvering.
• Hydraulic fluid leaks around the steering valve housing – Degraded O-rings or cracked casting surfaces allow oil seepage, leading to gradual pressure loss and contamination of adjacent components like the 4699102051: INPUT shaft.
• Increased steering effort or dead spots in the wheel – Internal spool wear reduces flow efficiency, requiring the operator to apply excessive force to achieve normal turning angles.
• Unusual whining or grinding noises during turns – Metal debris from a failing steering part can contaminate the hydraulic circuit, damaging the 4699103012: OUTPUT gear set.

Technical Specifications

Compatibility

This steering component is engineered for ZF transmissions commonly used in wheel loaders, excavators, and telehandlers. It is a direct fit for the following ZF model families: WG180, WG200, WG211, and WG310. Always verify the existing steering valve configuration before installation. For complete steering system rebuilds, pair this part with the 4699005026: GK30 gear kit and the 4699101018: HOUSING to ensure proper alignment and sealing.
