ZF 4699.172.041 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.041 STEERING PARTS (SKU: 4699.172.041) is an OEM genuine steering component engineered for the demanding environment of construction machinery. This precision-machined part resides within the steering control assembly of ZF transmissions, directly governing hydraulic fluid direction to the steering cylinders. It interfaces critically with the 4699101046: HOUSING and the 4699301109: HOUSING to maintain proper alignment and pressure regulation. As a genuine OEM part, the 4699.172.041 ensures exact tolerances for consistent steering response under heavy loads.

Symptoms of Failure

• Erratic steering response or “jerky” wheel movement: When the 4699.172.041 wears, internal spool valves stick, causing delayed or uneven hydraulic flow during turns.
• Hydraulic oil seepage around the steering valve block: Degraded seals on this part lead to external leaks, often visible as drips near the 4699301017: BEARING COVER interface.
• Increased steering effort at low engine RPM: A worn steering part reduces pilot pressure, forcing operators to apply more force to the wheel during slow-speed maneuvering.
• Unusual whining or groaning noise from the steering circuit: Internal cavitation caused by a failing 4699.172.041 produces audible noise, especially when turning against a load.

Technical Specifications

Compatibility

This steering part is designed for ZF transmission models commonly used in wheel loaders, telehandlers, and excavators. It is a direct fit for the ZF WG180 and ZF WG200 series transmissions. It also integrates with the ZF Ergopower and ZF 4WG-200 series where steering control modules share this valve geometry. Always verify the 4699301085: COVER condition during replacement to ensure proper sealing.
