Overview
The ZF 0501.331.020 LINED CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the clutch pack assembly, this OEM genuine part transfers torque from the engine to the gearbox input shaft, enabling smooth gear engagement and power modulation. The SKU 0501.331.020 features a high-friction lining bonded to a precision-machined steel core, ensuring consistent clamping force under heavy loads. This disk works in concert with the 2098109042: DIFFERENTIAL to manage torque distribution, and its integrity directly affects the overall driveline efficiency of ZF powershift transmissions.
Symptoms of Failure
- Transmission gear slipping under load — When the lined clutch disk wears thin, the clutch pack fails to hold torque, causing the transmission to slip during acceleration or uphill climbs.
- Delayed or harsh engagement — Worn friction material leads to inconsistent clutch pack pressure, resulting in jerky shifts or a noticeable lag when selecting forward or reverse gears.
- Burning smell from transmission fluid — Overheated friction lining produces a distinct burnt odor, often accompanied by dark, contaminated oil, indicating the disk is glazed or disintegrating.
- Erratic transmission behavior in low-speed maneuvers — The vehicle may shudder or vibrate when creeping, as the worn disk cannot maintain smooth micro-slip control.

Compatibility
This lined clutch disk is specifically designed for ZF WG100, WG130, and WG131 powershift transmissions. It also fits select variants of the WG180 and WG200 series when used in the forward clutch pack. For differential-side torque management, pair this disk with the 2098309011: CROWN WHEEL and the 2099209001: DIFFERENTIAL assembly. The 2098309010: DIFFERENTIAL HOUSING provides the structural enclosure for these rotating components. Always verify spline count and stack height before installation.
