ZF 4699.172.011 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.011 STEERING PARTS is a critical OEM genuine component engineered for the hydraulic steering control system within ZF construction machinery transmissions. This precision-machined part regulates oil flow to the steering clutch pack, ensuring responsive directional changes under heavy load. As part of the valve body assembly, the SKU 4699.172.011 interfaces directly with the 4699004010: GK25LD gear kit and the 4699101002: HOUSING to maintain consistent hydraulic pressure. Without this steering component, the transmission cannot engage the steering function, making it indispensable for wheel loaders and graders operating in demanding environments.

Symptoms of Failure

• Erratic steering response or delayed engagement – Worn internal spools cause hesitation when turning, especially under load.
• Hydraulic oil leaks around the steering valve body – Degraded seals allow fluid to escape, visible as drips near the 4699102010: INPUT connection.
• Unusual whining or chattering noise during turns – Metal-to-metal contact from worn steering parts creates audible vibration.
• Transmission overheating during prolonged steering – Internal leakage generates excess heat, accelerating wear on the 4699103002: OUTPUT shaft assembly.

Technical Specifications

Compatibility
