ZF 0730.103.766 WASHER for WG100 | OEM Genuine Part

Overview

The ZF 0730.103.766 WASHER for WG100 is a precision-engineered OEM genuine component designed to maintain critical sealing and load distribution within the WG 100 series transmission assembly. This hardened steel washer sits between the transmission housing and the clutch drum assembly, acting as a thrust surface to absorb axial loads and prevent metal-on-metal contact. As an original ZF part, SKU 0730.103.766 ensures exact dimensional tolerances that aftermarket alternatives cannot replicate, directly supporting the longevity of adjacent components like the 4651101006: TRANSMISSION HOUSING and the 4651301034: HOUSING.

Symptoms of Failure

• Transmission oil leaks at the housing interface — A worn 0730.103.766 washer allows lateral movement, breaking the seal between the 0634303928: O-RING and the housing face, resulting in visible fluid seepage.
• Gear engagement hesitation or slipping — As the washer flattens or cracks, axial clearance increases, causing delayed clutch pack engagement under load.
• Metallic grinding noise during shifts — Degraded washer material permits direct contact between rotating and stationary components, generating audible wear debris.
• Increased vibration in neutral or drive — Loss of washer thickness alters the preload on the 4651301013: HOUSING, leading to driveline instability.

Technical Specifications

Compatibility

This washer is specifically engineered for the ZF WG 100 series transmissions, including models WG100, WG120, and WG150. It is also compatible with certain WG180 and WG200 variants that share the same clutch drum stack geometry. Always verify fitment against your transmission’s parts manual. For related sealing components, consider the 0630361028: SEALING CAP or the 4475280060: SCREW PLUG when rebuilding.
