Overview
The ZF 0630.513.037 SNAP RING is a precision-engineered retaining component designed specifically for the WG 150 series transmission. This OEM genuine part secures internal assemblies—such as shafts, bearings, and gear clusters—within the transmission housing, preventing axial displacement during high-torque operation. The SKU 0630.513.037 is critical for maintaining proper clearance and load distribution inside the gearbox. When installed correctly, this snap ring ensures that adjacent components like the 2095109020: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING remain securely positioned, reducing vibration and wear over the transmission’s service life.
Symptoms of Failure
- Transmission oil leaks around the housing: A worn or broken snap ring can allow internal components to shift, breaking seals and causing fluid seepage.
- Gear slipping or erratic engagement: When the snap ring fails to hold the 2095209037: DIFFERENTIAL in place, gear alignment is compromised, leading to intermittent power loss.
- Unusual metallic rattling or grinding noises: Loose retaining rings permit axial play, causing metal-on-metal contact between the 2095309059: DIFF.HOUSING and adjacent gears.
- Increased drivetrain vibration at low speeds: A fatigued snap ring cannot maintain constant preload, resulting in harmonic oscillations that worsen over time.

Compatibility
This snap ring is engineered for the ZF WG 150 series, but its dimensions and load rating also make it suitable for select models in the WG 180 and WG 200 families. It is commonly used in heavy-duty off-highway transmissions, including those found in mining trucks, construction loaders, and agricultural tractors. For precise fitment, always verify the part number against your transmission’s serial plate. The ring works in conjunction with the 2095109020: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING to secure the differential assembly within the housing.
