Overview
The ZF 0730.308.096 SNAP RING is a critical retention component engineered for the WG190 and WG210 series transmissions. This OEM genuine part secures internal assemblies—such as bearing packs and gear clusters—within the main housing, preventing axial movement under high torque loads. The SKU 0730.308.096 is precision-machined to maintain exacting tolerances, ensuring that the transmission’s rotating elements remain properly aligned during operation. Without this snap ring, the structural integrity of the gear train is compromised, leading to premature wear on adjacent components like the 4657101088: TRANSMISSION HOUSING and the 4657201183: HOUS.FRONT SECT.
Symptoms of Failure
- Transmission oil leaks at the housing seam: A worn or deformed snap ring allows internal pressure to push lubricant past seals, often visible as drips near the 4657201184: HOUSING REAR PART interface.
- Gear slipping under load: When the snap ring loses its grip, axial play develops, causing gear engagement to become intermittent—especially during acceleration or hill climbing.
- Metallic rattling from the bell housing: Loose internal components strike the 4657298111: HOUSING REAR SECTION, producing a distinct noise that worsens with RPM changes.
- Difficult shifting between ranges: Misalignment caused by a failing snap ring creates binding in the shift mechanism, requiring excessive force to change gears.

Compatibility
This snap ring is designed for ZF transmissions in the WG and BP series. It fits the WG190 and WG210 models directly, and is also compatible with the BP 210 and BP 230 series. Additionally, it can be used in the WG180 and WG200 transmissions where the internal retaining groove dimensions match. Always verify the groove width in your specific TRANSMISSION HOUSING before installation.

Frequently Asked Questions
Q: Can I reuse the 0730.308.096 snap ring after removal?
A: ZF recommends replacing this snap ring with a new OEM part whenever it is removed, as the spring steel loses tension after initial installation and may not provide adequate retention.
Q: What tools are needed to install this snap ring?
A: Use snap ring pliers with 90-degree tips to expand the ring evenly. Avoid prying with screwdrivers, which can distort the ring and damage the housing groove.
Q: How do I verify the correct orientation of the snap ring?
A: The beveled edge of the snap ring should face the direction of thrust load. Consult your ZF service manual for the specific orientation in your WG190 or WG210 model.
