ZF 2098.328.059 WASHER | OEM Genuine Part

Overview

The ZF 2098.328.059 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearance within ZF heavy-duty transmission assemblies. This hardened steel washer sits between the differential housing and the bevel gear set, ensuring proper load distribution and preventing metal-to-metal contact under high torque conditions. As a factory-spec part, the SKU 2098.328.059 guarantees exact fitment and durability for construction machinery transmissions operating in demanding environments.

Symptoms of Failure

• Transmission oil leaks around the differential housing – When the washer wears beyond tolerance, it allows excessive movement that compromises seal integrity, leading to visible fluid seepage.
• Gear slipping under load during excavation – A degraded 2098.328.059 washer reduces preload on the BEVEL GEAR SET, causing intermittent power loss when the machine is under heavy strain.
• Metallic grinding noise from the axle area – Worn washers permit axial play that results in uneven tooth contact between the differential and bevel gears, producing a distinct grinding sound during turns.
• Premature wear of the differential assembly – Without proper washer thickness, the DIFFERENTIAL components experience accelerated fatigue, often requiring earlier-than-expected rebuilds.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series transmissions commonly used in construction machinery. It is a direct fit for the following models: WG180, WG200, WG211, and WG250. The 2098.328.059 washer is also compatible with select ZF differential assemblies, including the DIFFERENTIAL (part 2098209016) and the DIFF.HOUSING (part 2095309059). Always verify your transmission serial number before installation.
