ZF 0630.100.305 WASHER | OEM Genuine Part

Overview

The ZF 0630.100.305 WASHER is a precision-engineered OEM genuine component designed to maintain axial clearance and distribute load within the planetary gear sets of heavy-duty construction machinery transmissions. This hardened steel washer sits between rotating assemblies, such as the PLANET CARRIER and the WHEEL SHAFT, preventing metal-on-metal contact and ensuring consistent gear alignment. The SKU 0630.100.305 is a critical wear item that directly supports the structural integrity of the transmission’s power flow path.

Symptoms of Failure

• Transmission oil leaks at the housing interface: A worn 0630.100.305 washer can cause misalignment, leading to seal damage and visible fluid seepage around the HOUSING.
• Gear slipping under load: When this washer loses its thickness, axial play increases, allowing clutch packs to disengage prematurely during operation.
• Metallic grinding noise from the planetary section: Excessive clearance forces the BASIC PARTS assembly to vibrate, creating audible wear debris.
• Erratic shifting or delayed engagement: Loss of washer integrity alters hydraulic pressure feedback, causing hesitation in gear changes.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series transmissions commonly found in wheel loaders, excavators, and telehandlers. It is a direct fit for the following models: WG180, WG200, WG210, and WG310. The 0630.100.305 is also used in certain ZF Ergopower and Ecolife variants where planetary gear preload is critical. Always verify your transmission serial number before installation.
