Overview
The ZF 0730.514.796 SNAP RING is a precision-engineered retaining component specifically designed for the WG 90 and WG 94 series transmissions. This OEM genuine part functions as a critical axial locking mechanism, securing internal assemblies such as bearings, gears, and shafts within the transmission housing. Without this snap ring, the entire rotating assembly can shift under load, leading to misalignment and catastrophic failure. The SKU 0730.514.796 is manufactured to ZF’s exacting tolerances, ensuring a secure fit within the 4661101001: TRANSMISSION HOUSING and the 4661301007: HOUSING sub-assembly. This part is essential for maintaining the structural integrity of the gear train during high-torque operations.
Symptoms of Failure
When the ZF 0730.514.796 snap ring fatigues or breaks, several distinct failure modes emerge. Oil leaks at the housing seam occur because the snap ring no longer holds the bearing in place, allowing the shaft to wobble and compromise the seal. Gear slipping under load is another common symptom, as the axial clearance increases and the gears lose proper mesh alignment. Unusual metallic grinding noises from the transmission bell housing indicate that the snap ring has dislodged, allowing metal-on-metal contact between the rotating assembly and the housing. Difficulty engaging gears during shifting is also reported, caused by the internal components shifting out of their designed positions.

Compatibility
This snap ring is engineered for the ZF WG 90 and WG 94 series transmissions. It is directly compatible with models including the WG180, WG200, WG210, and WG240. The part also fits the WG 90-1 and WG 94-1 variants used in off-highway vehicles, construction equipment, and heavy-duty trucks. For proper installation, ensure the snap ring is seated fully within the groove of the 4661301093: TUBE and aligned with the 0631306174: CYLINDRICAL PIN to prevent rotation. Always verify your transmission serial number against the ZF parts catalog before ordering.
