ZF 0730.105.982 WASHER for WG100 | OEM Genuine Part

Overview

The ZF 0730.105.982 WASHER is a precision-engineered, OEM genuine component specifically designed for the WG 100 series transmission. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper clamp load distribution and preventing galling or deformation under high torque conditions. As an original equipment part, the SKU 0730.105.982 guarantees exact dimensional tolerances and material hardness required for reliable long-term service within the WG100 gearbox assembly. It is frequently replaced during major overhauls or when disassembling the TRANSMISSION HOUSING for seal or bearing replacement.

Symptoms of Failure

• Transmission oil seepage at housing bolt interfaces: A worn or crushed 0730.105.982 washer can allow bolt tension to relax, creating micro-gaps that lead to slow oil weeping around mounting points.
• Audible metallic clicking during gear engagement: When the washer loses its original thickness, fastener preload drops, permitting slight movement between the HOUSING components under load.
• Progressive gear slippage under heavy torque: Insufficient clamping force from a degraded washer can cause internal misalignment, reducing the transmission’s ability to hold gear position during high-stress operations.
• Visible corrosion or deformation on the washer face: Inspecting the part during service reveals pitting, edge rolling, or thickness reduction, indicating the need for immediate replacement.

Technical Specifications

Compatibility

This washer is a direct-fit component for the ZF WG 100 series transmission family. While primarily cataloged for the WG100, the 0730.105.982 also applies to the WG120, WG150, WG180, and WG200 models where identical bolt patterns and housing interfaces are used. It is commonly paired with the HOUSING assembly and the O-RING seal to ensure a leak-free joint. Always verify the specific housing configuration before installation, as some late-model WG200 units may use a different washer thickness.
