ZF 4699.172.101 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.101 STEERING PARTS component is a precision-engineered OEM genuine part designed for the hydraulic steering control system within heavy-duty construction machinery transmissions. This critical steering element interfaces directly with the valve body and hydraulic circuit to manage directional flow and pressure, ensuring responsive and accurate machine maneuvering. As a genuine ZF part, the SKU 4699.172.101 guarantees exact fitment and factory-specified performance, reducing the risk of premature wear in demanding off-road applications. It is commonly found in the steering column assembly of wheel loaders, graders, and telehandlers, where it works in concert with the 4699003012: GK20 gearbox kit to translate operator input into hydraulic commands.

Symptoms of Failure

• Steering wheel free play or excessive backlash: When the 4699.172.101 wears, operators may notice a dead zone in the steering wheel before the machine responds, indicating internal gear or valve wear.
• Hydraulic fluid leaks around the steering column: Deteriorated seals or housing cracks in this part often cause visible oil seepage, leading to low fluid levels and erratic steering behavior.
• Erratic or jerky steering response: A failing steering part can cause uneven hydraulic pressure delivery, resulting in sudden lurches or hesitation during turns, especially under load.
• Increased steering effort at low RPM: Worn internal components may require higher engine speed to achieve normal steering function, a common complaint in older ZF transmissions.

Technical Specifications

Compatibility

This genuine ZF steering part is engineered for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG250 series. It is also compatible with select ZF Ergopower and ZF Ecomat steering systems used in wheel loaders and excavators. For proper installation, this part should be paired with the 4699101045: HOUSING and the 4699102060: INPUT shaft assembly. The 4699103030: OUTPUT flange must also be inspected for wear during replacement to ensure complete system integrity.
