ZF 0730.002.750 WASHER | OEM Genuine Part

Overview

The ZF 0730.002.750 WASHER is an OEM genuine precision shim engineered for critical axial clearance control within ZF heavy-duty powershift transmissions. This hardened steel washer sits between the planetary gear set and the TRANSMISSION HOUSING, ensuring correct end-play tolerances for the rotating clutch packs. As a load-bearing component, it prevents metal-to-metal contact and maintains proper hydraulic pressure distribution. The SKU 0730.002.750 is specifically designed for construction machinery applications where vibration and thermal expansion demand exacting dimensional stability.

Symptoms of Failure

• Transmission oil leaks at housing seams – When the 0730.002.750 washer wears beyond its tolerance, the HOUSING seal surface shifts, causing fluid seepage around gasket interfaces.
• Gear slipping under load – A collapsed washer reduces clutch pack clamping force, leading to intermittent power loss during excavation or grading operations.
• Abnormal metallic grinding noise – Worn washer fragments contaminate the oil circuit, scoring planetary gears and the HOUSING interior surfaces.
• Erratic shift timing – Incorrect axial play from a degraded washer disrupts valve body feedback, causing delayed or harsh gear engagement.

Technical Specifications

Compatibility

This washer is a direct fit for ZF WG180, WG200, and WG210 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It also applies to select ZF 4WG-200 and 6WG-200 variants. Always verify axial clearance after installation using the CYLINDRICAL PIN alignment tool. For complete housing assembly, pair with the COVER and new gaskets to prevent contamination.
