ZF 4699.172.096 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.096 STEERING PARTS component is a critical OEM genuine part engineered for the hydraulic steering circuit within heavy-duty construction machinery transmissions. This precision-machined element regulates fluid flow to the steering control valve, ensuring responsive directional changes under high torque loads. As an integral part of the steering assembly, the SKU 4699.172.096 interfaces directly with the 4699101086 HOUSING and the 4699301223 HOUSING to maintain consistent hydraulic pressure. Designed for demanding environments, this part prevents internal leakage and supports precise articulation in wheel loaders, graders, and excavators. Replacing worn steering components with the OEM 4699.172.096 restores factory-spec performance and extends transmission service life.

Symptoms of Failure

• Erratic steering response or delayed engagement — When the 4699.172.096 wears, operators may notice a lag between steering wheel input and machine movement, often accompanied by a “spongy” feel in the controls.
• Hydraulic fluid leaks near the steering housing — Deteriorated seals or cracks in this part cause visible oil seepage around the 0636302022 SCREW PLUG and 0501319149 SCREW PLUG mounting points, leading to low fluid levels and overheating.
• Unusual whining or grinding noises during turns — Internal wear creates metal-on-metal contact, producing high-pitched sounds that intensify under load, signaling imminent failure of the steering circuit.
• Increased steering effort at low RPM — A failing part restricts oil flow, forcing the hydraulic pump to work harder, which can cause premature pump wear and reduced machine maneuverability.

Technical Specifications

Compatibility

This steering part is designed for ZF WG series transmissions commonly found in construction machinery. It is compatible with the following models: WG180, WG200, WG210, and WG240. These transmissions are used in articulated dump trucks, wheel loaders, and motor graders from OEMs such as Caterpillar, Volvo, and Komatsu. Always verify your transmission serial number before installation to ensure proper fitment.
