ZF 0730.103.767 WASHER for WG100 | OEM Genuine Part

Overview

The ZF 0730.103.767 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 100 series transmission family. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper clamp load distribution during assembly. Located within the main gear train assembly, the 0730.103.767 WASHER prevents galling and maintains axial clearance between rotating and stationary components. As an OEM genuine part, it meets ZF’s exacting tolerances for hardness, flatness, and corrosion resistance, making it essential for maintaining factory-specified transmission performance.

Symptoms of Failure

• Transmission oil seepage at housing joints — A worn or deformed 0730.103.767 WASHER can cause uneven bolt torque, leading to micro-gaps between the TRANSMISSION HOUSING and mating surfaces, resulting in slow oil weeping.
• Abnormal gear engagement noise — When the washer loses its original thickness, axial play increases, causing gear clash during shifts under load.
• Recurring bolt loosening — A crushed or fatigued washer fails to maintain preload, allowing fasteners to back out during operation, which may trigger vibration warnings.
• Metal debris in transmission fluid — Surface spalling of the washer introduces ferrous particles into the oil circuit, accelerating wear on downstream components.

Technical Specifications

Compatibility

This washer is engineered for the ZF WG 100 series, including models WG100, WG120, WG150, WG180, and WG200. It is commonly used in conjunction with the HOUSING assembly (part 4651301034) and the HOUSING (part 4651301013) to secure internal oil galleries. For proper sealing, always pair this washer with a new O-RING (part 0634303928) during reassembly. The 0730.103.767 WASHER is also compatible with earlier WG 80 and WG 90 variants when used as a direct replacement for worn factory washers.
