Overview
The ZF 0730.308.112 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 transmission housing, preventing axial movement under high torque loads. The SKU 0730.308.112 is precision-machined to maintain exacting tolerances, ensuring that shafts and gears remain locked in their designated positions during operation. Without this snap ring, the structural integrity of the gear train is compromised, leading to misalignment and accelerated wear on surrounding components like the 4657101088: TRANSMISSION HOUSING and the 4657201183: HOUS.FRONT SECT.
Symptoms of Failure
- Transmission oil leaks near the bell housing: A worn or broken snap ring allows internal components to shift, damaging seals and causing fluid to escape from the 4657201184: HOUSING REAR PART interface.
- Gear slipping under load: When the snap ring fails, gear clusters lose their axial lock, resulting in intermittent engagement and power loss during acceleration.
- Metallic grinding noises from the transmission: Loose components contact the 4657298111: HOUSING REAR SECTION, producing audible scraping or rattling sounds.
- Difficulty shifting between gears: Axial play from a degraded snap ring causes misalignment of shift forks, leading to hard or imprecise gear changes.

Frequently Asked Questions
Q: Can I reuse the ZF 0730.308.112 snap ring after disassembly?
No. Snap rings lose tension after removal. Always install a new OEM genuine part to prevent axial play and potential damage to the 4657201183: HOUS.FRONT SECT.
Q: What tools are required to install this snap ring?
Use snap ring pliers with 90-degree tips. Ensure the ring fully seats in the groove of the 4657101088: TRANSMISSION HOUSING to avoid improper retention.
Q: Does this part fit the WG180 transmission?
Yes, the WG180 shares the same snap ring groove dimensions as the WG190 and WG210 series. Verify with your 4657298111: HOUSING REAR SECTION for exact fitment.
