Overview
The ZF 0501.212.619 LINED CLUTCH DISK is a critical friction component engineered for the WG200 and WG92 series transmissions. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating shafts during gear engagement. Designed to withstand high thermal loads and repetitive cycling, the 0501.212.619 ensures smooth power delivery and precise shift timing. Its lined friction surface provides consistent clamping force, reducing wear on adjacent steel plates. For optimal transmission rebuilds, this disk works in concert with the 4660198001 PERIPHERALS kit to maintain hydraulic pressure integrity.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn 0501.212.619 causes slipping during acceleration, especially in higher gears, as the friction material loses its coefficient of grip.
- Burning smell from transmission fluid: Overheated clutch disk material produces a distinct acrid odor, often accompanied by dark, contaminated oil.
- Erratic shifting under load: When the lined surface glazes over, the transmission may hunt between gears or fail to hold torque during uphill climbs.
- Visible debris in oil pan: Friction material particles shed from a degraded disk accumulate in the sump, often clogging the 4660221012 SUCTION TUBE.

Compatibility
This lined clutch disk is specifically designed for ZF WG200 and WG92 series transmissions, including the WG180, WG200, and WG92 variants. It is a direct replacement for OEM assemblies in off-highway trucks, agricultural tractors, and industrial loaders. The 0501.212.619 interfaces directly with the 0501209818 RANGE SELECTOR valve body to control clutch pack pressure. For full rebuilds, verify compatibility with your 4660101011 TRANSMISSION HOUSING and 4660301018 HOUSING to ensure proper alignment of the clutch stack.
