ZF 4699.270.018 ASSEMBLY PARTS | OEM Genuine Part

Overview

The ZF 4699.270.018 ASSEMBLY PARTS component is a critical internal sub-assembly engineered for heavy-duty construction machinery transmissions. This OEM genuine part functions as a load-bearing interface within the planetary gearset, ensuring precise torque distribution and smooth power flow through the drivetrain. Specifically, the 4699.270.018 assembly integrates with the clutch pack and shaft system to manage gear engagement under high-stress operating conditions. When paired with the 4699100019: BASIC PARTS kit, it forms the foundational structure for reliable transmission performance. The SKU 4699.270.018 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in off-highway vehicles like wheel loaders and graders.

Symptoms of Failure

• Erratic gear engagement or slipping: When the 4699.270.018 assembly wears, operators often report delayed or rough shifting, especially under load. This is a common “ZF transmission slipping under load” issue.
• Metallic grinding noises from the transmission housing: Worn internal components produce distinct grinding sounds during acceleration or deceleration, indicating excessive play in the assembly.
• Oil contamination with metallic debris: As the assembly degrades, small metal particles enter the hydraulic fluid, causing “transmission oil full of metal shavings” scenarios that require immediate inspection.
• Reduced power transfer to wheels: A failing assembly leads to noticeable power loss, particularly in low-range gears, a symptom often searched as “construction machinery transmission power loss.”

Technical Specifications

Compatibility

This assembly is specifically designed for ZF’s WG series powershift transmissions used in construction machinery. It is a direct fit for the WG180, WG200, and WG250 models, which are commonly installed in brands like Liebherr, Volvo, and Caterpillar wheel loaders. The 4699.270.018 also integrates with the 4699300139: HOUSING and the 4699300156: GEAR SHAFT to complete the planetary gearset. For optimal performance, verify your transmission model’s serial number before ordering. This part is not compatible with ZF Ecomat or AS Tronic series.
