ZF 4699.172.025 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.025 STEERING PARTS component is a critical OEM genuine steering assembly designed for integration within heavy-duty construction machinery transmissions. This precision-engineered part controls hydraulic flow and mechanical linkage to the steering system, directly influencing vehicle maneuverability and operator control. Positioned within the transmission housing, it interfaces with the 4699100080: BASIC GEARBOX to ensure synchronized steering response under high torque loads. The SKU 4699.172.025 is manufactured to ZF’s exacting tolerances, making it essential for maintaining original equipment performance in excavators, loaders, and graders.

Symptoms of Failure

• Steering drift or unresponsive turning – When the 4699.172.025 wears, hydraulic pressure drops, causing the vehicle to drift left or right during operation, a common issue in construction machinery steering parts.
• Oil leaks around the steering housing – Degraded seals within this assembly lead to visible fluid seepage, often accompanied by a burnt hydraulic smell, indicating the need for immediate replacement alongside a 0634309122: SHAFT SEAL.
• Erratic steering feedback or vibration – Internal wear produces inconsistent resistance in the steering wheel, with vibrations transmitted through the column during low-speed maneuvers, a classic symptom of failing steering parts in ZF transmissions.
• Increased play or slack in the steering linkage – Excessive clearance develops over time, resulting in a noticeable dead zone before the wheels respond, often requiring inspection of the 0634801038: SEALING RING and 0630000091: SHIM RING.

Technical Specifications

Compatibility

This steering part is engineered for ZF WG series transmissions commonly deployed in construction machinery. It is compatible with the following ZF models: WG180, WG200, WG211, and WG250. These transmissions are found in articulated dump trucks, wheel loaders, and telehandlers. Always verify the SKU 4699.172.025 against your transmission serial number to ensure correct fitment. For optimal sealing integrity, pair this component with the 0634309122: SHAFT SEAL and 0634801038: SEALING RING to prevent premature wear.
