ZF 4699.172.082 STEERING PARTS | OEM Genuine Part

Overview

The ZF 4699.172.082 STEERING PARTS component is a critical OEM genuine part engineered for the hydraulic steering control assembly within ZF construction machinery transmissions. This precision-machined element governs directional fluid flow, enabling precise articulation in heavy equipment like wheel loaders and graders. As part of the steering valve stack, the SKU 4699.172.082 interfaces directly with the main control housing to modulate pressure for smooth turning operations. It is designed to withstand high cyclic loads and harsh operating environments, ensuring consistent response in demanding job site conditions.

Symptoms of Failure

• Erratic steering response or “jerky” turning: When the 4699.172.082 wears internally, operators may experience delayed or uneven steering input, particularly during low-speed maneuvering.
• Hydraulic fluid contamination in the steering circuit: Degraded seals within this part can allow debris into the system, leading to accelerated wear on downstream components like the 4699101049: HOUSING.
• External oil seepage around the steering column: Visible fluid leaks near the valve body often indicate failed O-rings or cracked housing interfaces, requiring immediate replacement of the 4699301188: HOUSING and associated seals.
• Increased steering effort or “heavy” steering: A worn part reduces hydraulic assist, forcing the operator to apply excessive force, which can strain the 0636015047: HEXAGON SCREW fasteners securing the assembly.

Technical Specifications

Compatibility

This steering part is primarily compatible with ZF WG180, WG200, and WG211 series transmissions used in construction machinery. It also fits select variants of the ZF 4WG-200 and 6WG-250 power shift transmissions. For proper installation, ensure the mating 4699301128: COVER is free of warpage and the sealing surfaces are clean. Always replace the 0734307406: SEALING RING and 0501319149: SCREW PLUG during service to prevent leaks.
