ZF 4699.172.103 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.103 STEERING PARTS component is a precision-engineered OEM genuine part designed for the hydraulic steering control assembly within ZF construction machinery transmissions. This critical element manages directional fluid flow to the steering cylinders, ensuring responsive and reliable machine maneuverability. As a factory-specified replacement, the SKU 4699.172.103 directly interfaces with the transmission’s valve body to regulate pressure and flow during low-speed turning operations. Its robust construction withstands the high cyclic loads typical of wheel loaders and graders, making it essential for maintaining precise steering authority in demanding job site conditions.

Symptoms of Failure

• Steering drift or wandering: When the 4699.172.103 component wears internally, the machine may drift to one side even with the wheel centered, indicating internal leakage past the steering spool.
• Hard steering or increased effort: A failing part can cause a noticeable increase in steering wheel torque, especially at low engine RPMs, as fluid bypasses the metering section.
• Oil leaks at the steering gear housing: External seepage around the mounting flange or shaft seal area often signals seal degradation within the 4699.172.103 assembly, leading to progressive fluid loss.
• Erratic or jerky steering response: Intermittent binding or sticking of the internal valve mechanism results in uneven steering feedback, particularly during fine maneuvering.

Technical Specifications

Compatibility

This steering part is primarily compatible with ZF WG180, WG200, and WG210 series powershift transmissions commonly used in construction machinery such as wheel loaders, telehandlers, and compact excavators. It also fits select applications in the ZF 4WG-200 and 6WG-200 transmission families. For precise fitment verification, always cross-reference the OEM part number 4699.172.103 against your transmission’s serial number plate. When replacing this component, it is advisable to inspect the adjacent 4699008047: GK16 gear kit and the 4699101093: HOUSING for wear, as these elements share the same hydraulic circuit. Additionally, the 4699102142: INPUT shaft and 4699103054: OUTPUT flange must be checked for spline damage during overhaul.
