ZF 4108.311.049 WASHER | OEM Genuine Part

Overview

The ZF 4108.311.049 WASHER is an OEM genuine thrust washer engineered for precise axial load management within ZF heavy-duty transmission assemblies. This component sits between rotating gear sets and stationary housings, acting as a sacrificial wear surface that maintains critical clearances under high torque conditions. The SKU 4108.311.049 is specifically designed to prevent metal-on-metal contact in planetary gear sections, ensuring smooth power flow in construction machinery transmissions. When paired with a 4108101057 HOUSING or a 4108201177 HOUSING, this washer forms a sealed boundary that protects internal components from debris ingress and lubricant loss.

Symptoms of Failure

• Transmission oil leaks at housing seams — When the 4108.311.049 washer wears beyond tolerance, it allows pressurized oil to escape between the BEARING COVER and housing, creating visible drips on the transmission exterior.
• Gear slipping under load — A collapsed washer reduces axial preload, causing planetary gear sets to lose engagement during heavy digging or lifting operations.
• Metallic grinding noise during shifting — Worn washer fragments contaminate the oil system, leading to audible scraping between gear teeth and the SCREW PLUG threads.
• Erratic clutch engagement — Thickness loss in the washer alters piston stroke, delaying clutch pack activation and producing harsh shifts in WG-series transmissions.

Technical Specifications

Compatibility

This thrust washer is a direct fit for ZF WG180, WG200, and WG210 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It also applies to select ZF 4WG-200 and 6WG-200 off-highway gearboxes. For proper installation, always replace the 4108306173 GASKET and 0750110040 SHAFT SEAL simultaneously to prevent cross-contamination from old sealing surfaces.
