Overview
The ZF 0501.212.371 FRICTION DISC is a critical wear component engineered specifically for the clutch pack assemblies within the WG190 and related heavy-duty transmission series. This OEM genuine part ensures precise torque transfer and smooth gear engagement by providing the necessary frictional surface between rotating steel plates. Located inside the clutch drum, the SKU 0501.212.371 works in concert with the TRANSMISSION HOUSING to maintain hydraulic pressure integrity and prevent power loss during high-load operations.
Symptoms of Failure
- Delayed or harsh gear engagement: When the friction material wears thin, you may notice a lag when shifting from neutral to drive or reverse, often accompanied by a jarring thud.
- Transmission slipping under load: A worn 0501.212.371 disc causes the clutch pack to lose grip, resulting in RPM flare-ups without corresponding vehicle acceleration, especially on inclines.
- Burnt transmission fluid odor: Excessive heat from friction disc slippage degrades the ATF, producing a distinct burnt smell and darkening the fluid color.
- Metallic debris in the oil pan: As the friction lining disintegrates, particles accumulate in the sump, often visible during routine fluid changes or when inspecting the HOUS.FRONT SECT.

Compatibility
This friction disc is designed for ZF WG-series powershift transmissions, including the WG180, WG190, WG191, WG200, WG210, and WG230 models. It also fits select BP-series units such as the BP210 and BP230. The part is typically used in the forward clutch pack and requires proper alignment with the HOUSING REAR PART and the CYLINDRICAL PIN for correct assembly. Always verify the number of friction and steel plates in your specific transmission model before installation.
