ZF 4699.172.092 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.092 STEERING PARTS is a precision-machined OEM genuine component designed for the hydraulic steering control system within ZF construction machinery transmissions. This part functions as a critical valve or actuator element that modulates oil flow to the steering cylinders, ensuring precise directional control under heavy loads. It sits within the upper valve body assembly of the transmission, directly interfacing with the 4699101093: HOUSING to maintain proper hydraulic pressure. The SKU 4699.172.092 is engineered to withstand high cyclic pressures and abrasive contaminants common in earthmoving equipment.

Symptoms of Failure

• Erratic steering response or “jerky” turning – When the 4699.172.092 wears internally, hydraulic fluid bypasses the metering edges, causing uneven power delivery to the steering gear.
• External oil seepage around the valve body – Degraded sealing surfaces allow transmission fluid to weep past the 0634303936: O-RING, leaving visible drips on the housing.
• Increased steering effort at low engine RPM – A worn part reduces pilot pressure, requiring the operator to apply more force to the steering wheel during slow-speed maneuvers.
• Unintended drift or “wandering” – Internal leakage causes the machine to slowly turn without driver input, a dangerous condition often traced to this steering component.

Technical Specifications

Compatibility

This steering part is primarily used in ZF WG180, WG200, and WG211 series power shift transmissions found in wheel loaders, graders, and telehandlers. It also fits select models of the ZF Ergopower and Ecolife series when equipped with hydraulic steering valve bodies. For proper assembly, ensure the 4699301175: HOUSING and 4699301041: COVER are inspected for wear simultaneously.
