ZF 4699.172.055 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.055 STEERING PARTS is a critical OEM genuine component engineered for the hydraulic steering system within ZF construction machinery transmissions. This part functions as a precision-machined valve or actuator element, directing oil flow to control articulation and steering response in heavy-duty loaders and graders. It sits within the transmission control housing, interfacing directly with the 4699101107: HOUSING to regulate pressure distribution. The SKU 4699.172.055 ensures exact fitment and durability under high-cycle industrial use, eliminating aftermarket tolerance issues.

Symptoms of Failure

• Erratic steering response or delayed articulation – When the 4699.172.055 wears, internal clearances increase, causing sluggish or jerky steering movements, especially under load.
• External hydraulic oil leaks near the steering control block – Degraded seals or micro-cracks in this part lead to visible fluid seepage around the 4699102151: INPUT connection points.
• Increased steering effort or “spongy” feel – Worn steering parts fail to maintain proper pilot pressure, requiring the operator to exert more force on the wheel for the same turning radius.
• Unusual whining or groaning noises during turns – Cavitation or metal-to-metal contact inside the steering circuit indicates imminent failure of this OEM component.

Technical Specifications

Compatibility

This steering part is designed for integration into ZF’s WG series powershift transmissions commonly found in construction machinery. It is compatible with the following ZF transmission models: WG180, WG200, WG211, and WG250. It also fits select variants of the WG310 series used in large wheel loaders. For proper assembly, this part works in conjunction with the 4699103113: OUTPUT shaft and the 4699008042: GK16 gear kit. Always verify your transmission serial number before ordering.
