ZF 0630.505.506 SNAP RING | OEM Genuine Part

Overview

The ZF 0630.505.506 SNAP RING is a precision-engineered retaining component designed to secure internal assemblies within ZF heavy-duty transmissions. This OEM genuine part functions as a positive axial lock, preventing lateral movement of gears, bearings, and shafts under high torque loads. Installed within the differential housing assembly, it works in concert with the 2098309010: DIFFERENTIAL HOUSING to maintain critical clearances. The SKU 0630.505.506 is manufactured to exacting tolerances, ensuring a secure fit that eliminates vibration-induced loosening in construction machinery transmissions.

Symptoms of Failure

• Transmission oil leaks at axle housing – A worn or broken snap ring allows the differential carrier to shift, breaking the seal between the 2098109042: DIFFERENTIAL and housing, leading to external fluid seepage.
• Gear slipping under load – When the snap ring loses tension, the 2098309011: CROWN WHEEL can drift axially, causing intermittent engagement and power loss during excavation or grading.
• Abnormal whining or clunking noises – A fatigued snap ring permits excessive end-play in the 2099209001: DIFFERENTIAL assembly, generating metallic chatter during deceleration or turns.
• Premature bearing wear – Loss of axial retention forces the thrust washers and bearings to absorb unintended loads, accelerating failure of adjacent components.

Technical Specifications

Compatibility

This snap ring is engineered for ZF powershift and mechanical transmissions commonly used in wheel loaders, dozers, and graders. It is a direct fit for the following ZF models: WG180, WG200, WG210, WG250, and WG310 series. It also applies to select ZF 4WG-200 and ZF 6WG-250 transfer cases. Always verify groove dimensions against your specific housing bore before installation.
