Overview
The ZF 0501.212.370 DISC is a critical friction component engineered specifically for the WG190 and related heavy-duty transmission series. Positioned within the clutch pack assembly, this OEM genuine part ensures precise torque transfer and smooth gear engagement under high-load conditions. As an original equipment manufacturer component, the SKU 0501.212.370 guarantees exact fitment and durability, reducing downtime in industrial applications. This disc works in concert with the TRANSMISSION HOUSING to maintain proper alignment and oil flow, while the HOUS.FRONT SECT and HOUSING REAR PART provide structural integrity for the entire assembly.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn friction material causes slipping during shifts, especially under load.
- Transmission overheating: Excessive heat generation from disc slippage leads to fluid degradation and potential seal damage.
- Metallic debris in oil pan: As the disc wears, fine metal particles contaminate the hydraulic system, often requiring a CYLINDRICAL PIN inspection.
- Intermittent power loss: The transmission may fail to hold torque during acceleration, indicating disc glazing or warping.
