ZF 0730.306.451 WASHER | OEM Genuine Part

Overview

The ZF 0730.306.451 WASHER is an OEM genuine shim component engineered for precise axial clearance control within heavy-duty construction machinery transmissions. This hardened steel washer sits between the planetary gear carrier and the housing assembly, ensuring correct preload and alignment of rotating elements. The SKU 0730.306.451 is critical for maintaining optimal gear mesh patterns and preventing excessive end-play in ZF power shift transmissions. When paired with the 4699101159 HOUSING or the 4699301254 HOUSING, this washer forms a sealing and spacing boundary that directly influences clutch pack engagement timing.

Symptoms of Failure

• Transmission oil seepage at housing joints: A worn 0730.306.451 washer allows the housing faces to shift, breaking the seal created by the 4699298049 HOUSING KIT, leading to visible oil weeping around the transmission case.
• Intermittent gear slipping under load: When this washer loses its original thickness, axial play increases, causing clutch packs to partially disengage during high-torque operations in construction machinery.
• Metallic grinding noise from the transmission sump: A collapsed or fractured washer permits metal-on-metal contact between the gear carrier and the 4699309123 HOUSING COVER, generating fine debris in the oil.
• Erratic shift timing in forward/reverse: Incorrect washer stack height alters the hydraulic clearance, producing delayed or harsh gear engagements in ZF WG-series transmissions.

Technical Specifications

Compatibility

This washer is designed for ZF WG180, WG200, and WG210 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It also fits select ZF 4WG-200 and 6WG-200 power shift models. Always verify the stack height requirement against your specific transmission serial number. For complete housing restoration, inspect the 0636104255 CAP SCREW and 0631306174 CYLINDRICAL PIN for wear during reassembly.
