ZF 4699.172.049 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.049 STEERING PARTS component is a critical OEM genuine steering control element engineered for demanding construction machinery applications. This precision-machined part regulates hydraulic flow within the steering circuit of ZF transmissions, ensuring responsive directional control and load stability during operation. As a factory-specified replacement, the SKU 4699.172.049 interfaces directly with the transmission housing assembly to modulate steering pressure. For optimal sealing integrity, this component is frequently installed alongside the 4699101095: HOUSING and the 0501329881: HOUSING COVER, which provide structural support and contamination protection.

Symptoms of Failure

• Erratic steering response or delayed engagement – When the 4699.172.049 wears internally, operators may notice hesitation or jerky movements when turning, especially under load.
• Hydraulic oil leaks around the steering assembly – Deteriorated seals or internal wear can cause fluid seepage, often visible near the 0634306309: O-RING interface.
• Increased steering effort or stiff operation – A failing part reduces hydraulic assist, requiring more force to turn the machine, particularly at low engine RPM.
• Unusual whining or groaning noises during turns – Cavitation or internal scoring generates audible distress signals, indicating imminent component failure.

Technical Specifications

Compatibility

This steering part is designed for ZF power shift transmissions commonly found in wheel loaders, telehandlers, and excavators. It is compatible with the following ZF transmission models: WG180, WG200, WG211, and WG310. Always verify the 0769100082: TYPE PLATE on your transmission for exact model confirmation. The part also integrates with the 0637885612: BREATHER to maintain proper pressure equalization within the steering circuit.
