Overview
The ZF 0501.326.563 OUTER 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 between rotating shafts and stationary housings during gear shifts. The SKU 0501.326.563 ensures precise engagement and disengagement of the clutch system, directly influencing shift quality and driveline efficiency. This outer disk works in concert with the 4699101070: HOUSING and the 4699301146: HOUSING to maintain proper hydraulic pressure and alignment within the transmission assembly.
Symptoms of Failure
- Delayed or harsh shifting: Worn friction material on the 0501.326.563 outer clutch disk causes hesitation or abrupt engagement during gear changes, especially under load.
- Transmission fluid overheating: Slipping disks generate excessive heat, leading to burnt-smelling fluid and potential damage to the 4699309085: HOUSING COVER from thermal expansion.
- Loss of torque in forward or reverse: A failing outer disk cannot hold hydraulic pressure, resulting in reduced power transfer and vehicle creep issues.
- Metallic debris in oil pan: Worn clutch material contaminates the transmission fluid, often requiring replacement of the 0636101411: CAP SCREW and associated seals during overhaul.

Compatibility
This outer clutch disk is specifically designed for ZF WG100, WG130, and WG131 transmissions. It is also compatible with WG180 and WG200 series when used in identical clutch pack configurations. Always verify the clutch stack height and spline count against your transmission’s service manual. For complete assembly, pair this disk with the 0631302212: CYLINDRICAL PIN and 0634801038: SEALING RING to prevent fluid bypass.
