Overview
The ZF 0501.224.504 LINED CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the clutch pack assembly, where it transfers torque from the engine to the gearbox via hydraulic pressure. Designed to withstand high thermal loads, the lined friction surface ensures smooth engagement and disengagement during shifting. The SKU 0501.224.504 is a direct replacement for worn units, restoring transmission efficiency and preventing power loss. When installed alongside the 4143101009: HOUSING and 4143301025: HOUSING, this disk maintains proper alignment within the clutch drum.
Symptoms of Failure
- Transmission gear slipping under load: A worn 0501.224.504 disk loses friction material, causing the clutch to slip during acceleration or uphill driving. This often triggers diagnostic trouble codes for clutch pressure.
- Delayed or harsh gear engagement: When the lined surface becomes glazed or worn, shifts feel jerky or take longer than normal. This symptom is common in WG100 and WG130 units with high mileage.
- Burning smell from transmission fluid: Excessive heat from friction generates a distinct burnt odor, indicating the disk is no longer gripping properly. Immediate replacement prevents damage to the 0634313603: O-RING and adjacent seals.
- Fluid contamination with dark particles: As the friction lining degrades, debris enters the hydraulic circuit. This can clog the 4475280018: SCREW PLUG passages and reduce overall system pressure.

Compatibility
This clutch disk is specifically designed for ZF WG100, WG130, and WG131 transmissions. It is also compatible with select WG180 and WG200 variants that share the same clutch pack dimensions. Always verify the spline count and friction plate stack height before installation. For complete assembly, pair this disk with the 0501342341: SUPPORT RING to ensure proper spacing, and replace the 4143298457: SEAL KIT to prevent fluid leaks.
