Overview
The ZF 0630.307.016 SPRING WASHER is a precision-engineered OEM genuine component designed for the WG100, WG130, and WG131 transmission series. This critical fastener element provides the necessary preload and tension within the clutch pack and planetary gear assemblies, ensuring consistent clamping force under high-torque conditions. The SKU 0630.307.016 sits directly between the 4699101080: HOUSING and the 0501329881: HOUSING COVER, where it maintains axial clearance and absorbs vibrational loads during gear shifts. Without this spring washer, the transmission’s internal components would experience excessive play, leading to premature wear of adjacent parts.
Symptoms of Failure
When the ZF 0630.307.016 spring washer fatigues or loses its elastic memory, operators typically notice three distinct failure modes. First, intermittent gear slipping under load occurs because the washer can no longer maintain proper clutch pack pressure. Second, audible rattling or clunking from the transmission housing during deceleration indicates that the washer has collapsed, allowing axial movement between the 0630513065: SNAP RING and the housing assembly. Third, erratic shift timing manifests as delayed or harsh engagements, often misdiagnosed as a valve body issue. Fourth, metal debris in the transmission fluid signals that the washer has fractured, potentially damaging the 0634306309: O-RING and adjacent sealing surfaces.

Compatibility
This spring washer is specifically engineered for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It also fits select WG180 and WG200 variants where the clutch pack stack height matches the 30mm outer diameter specification. The part is not interchangeable with earlier ZF 4HP or 5HP series due to differing housing geometries. For correct installation, always verify that the washer sits flush against the 4699101080: HOUSING shoulder before securing the 0501329881: HOUSING COVER.
