ZF 0630.513.117 SNAP RING for WG150/WG200/WG201 | OEM Genuine Part

Overview

The ZF 0630.513.117 SNAP RING is a critical retaining component engineered for the WG150, WG200, and WG201 transmission series. This OEM genuine part secures internal assemblies—such as gear clusters and bearing packs—within the main housing, preventing axial displacement during high-torque operation. The SKU 0630.513.117 fits precisely into machined grooves to lock shafts and planetary carriers in place. When paired with a robust TRANSMISSION HOUSING (4642101109) or a TRANSMISSION HOUSING (4642301205), this snap ring ensures the entire drivetrain remains rigid under load. Its installation is often coordinated with a TYPE PLATE (0730365125) for correct identification and a GROOVED STUD (0631311009) for secure fastening.

Symptoms of Failure

• Transmission oil leaks near the housing seam: A worn or broken snap ring allows internal components to shift, breaking housing seals and causing fluid loss.
• Gear slipping under load: When the snap ring fails to retain shafts, gear engagement becomes inconsistent, leading to sudden slippage during acceleration.
• Metallic grinding noises from the bell housing: A dislodged snap ring permits metal-on-metal contact between rotating parts, producing a distinct grinding sound.
• Erratic shift timing: Axial play from a compromised snap ring disrupts hydraulic valve timing, causing delayed or harsh gear changes.

Technical Specifications

Compatibility

This snap ring is designed exclusively for ZF WG-series transmissions. It is a direct fit for the WG150, WG200, and WG201 models. It also applies to the WG180 variant, which shares the same internal groove dimensions. The part is not interchangeable with older ZF Ecomat or AS Tronic series due to differing housing diameters. Always verify the groove width in your specific housing before installation.
