ZF 0730.002.752 WASHER | OEM Genuine Part

Overview

The ZF 0730.002.752 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearance and load distribution within heavy-duty construction machinery transmissions. This hardened steel washer sits between the transmission housing and rotating shaft assemblies, preventing metal-on-metal contact and ensuring proper gear alignment under extreme torque loads. As a factory-specified shim, the SKU 0730.002.752 plays a vital role in controlling end-play within planetary gear sets, directly impacting shift quality and overall drivetrain longevity. When paired with a properly sealed 2094101012: TRANSMISSION HOUSING, this washer helps maintain the precise tolerances required for ZF’s robust power-shift systems.

Symptoms of Failure

• Transmission oil leaks at housing mating surfaces — A worn 0730.002.752 washer allows excessive axial movement, distorting the 2094301036: HOUSING seal interface and causing fluid seepage around the output shaft.
• Intermittent gear slipping under load — When this washer loses its original thickness, clutch pack clearance increases, leading to delayed engagement and torque loss during excavation or grading operations.
• Metallic grinding noise from the transmission sump — A collapsed or fractured 0730.002.752 permits gear clash between the planetary carrier and the 2094298057: HOUSING, producing audible debris contamination.
• Erratic shift timing in cold-start conditions — Thermal expansion differences become problematic when the washer is compressed beyond spec, causing delayed hydraulic pressure buildup in the 2094301071: COVER assembly.

Technical Specifications

Compatibility

This washer is integral to ZF’s WG-series power-shift transmissions commonly deployed in wheel loaders, graders, and telescopic handlers. It is a direct fit for the WG180, WG200, and WG210 models, where it functions as a thrust washer between the input shaft and the main housing bore. The 0730.002.752 also appears in certain 4WG-200 and 6WG-250 variants used in off-highway dump trucks. Always verify axial clearance specifications when replacing this part alongside the 2094101012: TRANSMISSION HOUSING to prevent preload errors.
