ZF 0730.104.724 WASHER for WG100 | OEM Genuine Part

Overview

The ZF 0730.104.724 WASHER is a precision-engineered OEM genuine component designed for the WG 100 Series transmission family. This hardened steel washer serves as a critical load-spreading interface between fasteners and mating surfaces within the transmission housing assembly. Specifically, it sits between the TRANSMISSION HOUSING and adjacent components, ensuring proper clamp load distribution and preventing galling or deformation under high torque conditions. The SKU 0730.104.724 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit and long service life in heavy-duty industrial applications.

Symptoms of Failure

• Oil seepage at housing joints: A worn or deformed washer 0730.104.724 can cause uneven clamping pressure, leading to transmission fluid leaks around the HOUSING interface.
• Gear engagement noise: When this washer loses its thickness, fastener preload drops, allowing slight movement that produces audible clunking during shifts.
• Torque loss at mounting bolts: Repeated thermal cycling can compress the washer beyond spec, causing bolts to loosen and resulting in vibration or slipping under load.
• Premature O-ring failure: A collapsed washer reduces sealing pressure on the adjacent O-RING, accelerating fluid bypass and contamination.

Technical Specifications

Compatibility

This washer is specifically validated for the ZF WG 100 Series, including models WG100, WG120, and WG150. It also fits select WG180 and WG200 variants where the HOUSING design uses M14 fasteners. Always verify your transmission’s housing configuration before ordering. For WG200 units with modified oil circuits, pair this washer with the SCREEN SHEET (4651301015) for optimal filtration.
