ZF 0630.513.136 SNAP RING for WG100 | OEM Genuine Part

Overview

The ZF 0630.513.136 SNAP RING is a precision-engineered retaining component designed specifically for the WG 100 series transmission assembly. This OEM genuine part secures critical internal assemblies, such as planetary gear sets and bearing packs, within the transmission housing. By locking components axially in place, it prevents unwanted movement that could lead to misalignment or mechanical interference. The SKU 0630.513.136 is a direct replacement for the original factory-installed snap ring, ensuring exact fitment and load distribution. This part is typically installed adjacent to the 4651101009: TRANSMISSION HOUSING and works in conjunction with the 4651301025: HOUSING to maintain structural integrity under high torque conditions.

Symptoms of Failure

When the ZF 0630.513.136 snap ring fatigues or breaks, operators may notice distinct failure modes. Intermittent gear slippage under load is a common early indicator, as the ring loses its grip on internal shafts. Metallic rattling or grinding noises from the transmission housing often accompany a fractured ring, signaling loose components. Sudden loss of drive in forward or reverse gears can occur if the ring fails completely, allowing a gear set to shift out of position. Additionally, oil leaks near the housing seam may develop if the ring’s failure allows the 0634303928: O-RING to become unseated, compromising the seal.

Technical Specifications

Compatibility

This snap ring is engineered for the ZF WG 100 series, but it also fits select models in the WG 180 and WG 200 families due to shared internal architecture. It is a critical component in the 4651301031: HOUSING assembly. Compatible transmissions include the WG100, WG120, WG180, and WG200 series, particularly those built between 2005 and 2020. Always verify the housing bore diameter before installation.
