ZF 0730.106.773 WASHER | OEM Genuine Part

Overview

The ZF 0730.106.773 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearance and distribute clamping loads within ZF heavy-duty construction machinery transmissions. This hardened steel washer sits between rotating shafts and stationary housings, preventing metal-to-metal contact and ensuring proper preload in the planetary gear sets. The SKU 0730.106.773 is a direct factory replacement part, essential for maintaining the integrity of the transmission’s internal geometry. When installed alongside the 4108101057 HOUSING and 4108201177 HOUSING, this washer ensures that bearing races and gear assemblies remain correctly positioned under heavy torque loads.

Symptoms of Failure

When the ZF 0730.106.773 WASHER wears beyond tolerance, operators will notice distinct performance issues. Transmission oil leaks from the housing interface occur when the washer compresses unevenly, allowing fluid to bypass the 4108301304 BEARING COVER seal. Gear slipping under load is a common complaint, as insufficient washer thickness reduces clamping force on the planetary carrier. Abnormal whining or grinding noises from the transmission indicate that the washer has failed to maintain proper bearing preload, leading to excessive axial play. Difficulty engaging gears or delayed shifting in construction machinery often traces back to a collapsed or deformed washer that alters the transmission’s internal clearances.

Technical Specifications

Compatibility

This washer is a standard component across multiple ZF power shift transmission families used in construction machinery. It is commonly found in the WG180, WG200, and WG210 series transmissions, where it functions as a thrust washer in the input shaft and planetary carrier assemblies. The 0730.106.773 also appears in WG150 and WG250 models, particularly in applications involving the 0636302056 SCREW PLUG retention system. Always verify the washer thickness against your transmission’s service manual, as multiple shim variants exist for fine-tuning endplay.
