ZF 4699.172.046 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.046 STEERING PARTS component is a precision-engineered OEM genuine part designed for the hydraulic steering system within ZF construction machinery transmissions. This part functions as a critical control element, managing fluid flow and pressure to ensure responsive steering in heavy-duty equipment. Positioned within the transmission valve body assembly, the SKU 4699.172.046 interfaces directly with the 4699101081: HOUSING to maintain sealed hydraulic circuits. As an OEM genuine part, it guarantees exact fitment and long-term reliability under extreme operating loads.

Symptoms of Failure

• Erratic steering response or delayed engagement: When the 4699.172.046 wears, operators notice hesitation or jerky movements during low-speed maneuvers, often accompanied by a grinding noise from the steering column.
• Hydraulic fluid leaks near the valve body: Worn seals or internal scoring cause visible oil seepage around the 0501329881: HOUSING COVER, leading to gradual fluid loss and reduced system pressure.
• Increased steering effort at idle: A failing part restricts fluid bypass, forcing the operator to apply excessive force to turn the wheel, particularly when the machine is stationary.
• Intermittent loss of power steering: The steering may suddenly become heavy during operation, indicating internal valve sticking or contamination from degraded 0634306309: O-RING seals.

Technical Specifications

Compatibility

This steering part is engineered for ZF WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, excavators, and telehandlers. It is also compatible with select ZF 4WG-180 and 4WG-200 variants used in construction machinery. The 4699.172.046 integrates with the 0637885612: BREATHER assembly to maintain atmospheric pressure within the steering circuit. Always verify your transmission model suffix before ordering.
