ZF 0730.008.729 WASHER | OEM Genuine Part

Overview

The ZF 0730.008.729 WASHER is a precision-engineered OEM genuine component designed for critical load distribution within heavy-duty construction machinery transmissions. This hardened steel washer sits between the transmission housing and rotating shaft assemblies, ensuring proper axial clearance and reducing friction during high-torque operations. As part number 0730.008.729, it functions as a thrust washer in planetary gear sets, directly interfacing with the 2094101014: TRANSMISSION HOUSING to maintain gear alignment under extreme loads. Its role is vital for preventing metal-on-metal contact between the 2094301046: HOUSING components and rotating elements, extending the service life of adjacent assemblies.

Symptoms of Failure

• Transmission oil leaks near the housing joint — When the 0730.008.729 washer wears beyond tolerance, it creates uneven gaps that compromise the seal between the 2094298053: HOUSING and the 0630361034: SEALING CAP, leading to visible fluid seepage during operation.
• Gear slipping under load in construction machinery — A flattened or cracked washer reduces axial preload, causing planetary gears to momentarily disengage when torque spikes occur during digging or lifting cycles.
• Metallic grinding noises from the transmission sump — Advanced wear produces fine steel particles that contaminate the oil, generating audible scraping sounds as the washer disintegrates against the housing face.
• Erratic shift timing in ZF powershift transmissions — Insufficient washer thickness alters clutch pack clearance, resulting in delayed or harsh gear engagement that operators notice during directional changes.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series powershift transmissions commonly used in wheel loaders, excavators, and telehandlers. It is a direct fit for the following models: WG180, WG200, WG210, and WG250. The 0730.008.729 also appears in certain ZF 4WG-200 and 6WG-200 variants where it serves as the primary thrust washer for the input shaft assembly. Always verify your transmission serial number against the OEM parts catalog before ordering.
