ZF 0730.306.449 WASHER | OEM Genuine Part

Overview

The ZF 0730.306.449 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearance and sealing pressure within heavy-duty ZF transmissions. This hardened steel washer sits between the planetary gear set and the housing assembly, preventing metal-on-metal contact and ensuring consistent load distribution during high-torque operations. As a factory-spec replacement for construction machinery transmissions, the SKU 0730.306.449 is essential for restoring factory tolerances during rebuilds. It is frequently replaced alongside the 4699101159 HOUSING and the 4699301254 HOUSING to guarantee proper alignment in the clutch pack assembly.

Symptoms of Failure

• Transmission oil leaks at the housing interface – A worn 0730.306.449 washer reduces sealing force, allowing ATF to seep past the 4699298049 HOUSING KIT gasket surface.
• Intermittent gear slipping under load – When the washer thickness degrades, clutch pack clearance increases, causing delayed engagement in WG180 and WG200 series transmissions.
• Metallic debris in the oil pan – Flattening or cracking of the washer generates fine steel particles that contaminate the hydraulic circuit.
• Abnormal vibration during PTO operation – Loss of axial preload from a collapsed washer creates harmonic resonance in the output shaft housing.

Technical Specifications

Compatibility

This washer is a direct fit for ZF WG180, WG200, and WG210 series powershift transmissions commonly used in wheel loaders, graders, and excavators. It also applies to ZF 4WG-200 and 6WG-200 variants. Always verify clearance with the 4699309123 HOUSING COVER during installation. For complete rebuilds, pair this washer with the 0636104255 CAP SCREW and 0631306174 CYLINDRICAL PIN to secure the housing assembly.
