ZF 0501.220.268 INNER CLUTCH DISK for WG94

Overview

The ZF 0501.220.268 Inner Clutch Disk is a critical friction component engineered specifically for the WG 94 series transmission. This OEM genuine part resides within the clutch pack assembly, where it transfers torque between rotating elements during gear shifts. The 0501.220.268 disk ensures precise engagement and disengagement of the clutch, directly influencing shift quality and overall driveline efficiency. It works in conjunction with the TRANSMISSION HOUSING and HOUSING II to maintain proper alignment and hydraulic pressure within the transmission.

Symptoms of Failure

• Delayed or harsh gear engagement: When the inner clutch disk wears, you may notice a pronounced lag or jarring sensation when shifting from neutral to drive or reverse.
• Transmission slipping under load: Worn friction material causes the clutch to lose grip, resulting in RPM flare without corresponding vehicle acceleration, especially during uphill climbs.
• Burning smell or discolored transmission fluid: Excessive heat from slipping friction surfaces generates a distinct burnt odor and darkens the ATF, indicating imminent disk failure.
• Erratic shift patterns: The transmission may hunt between gears or fail to hold a gear, as the worn disk cannot maintain consistent clamping force.

Technical Specifications

Compatibility

This inner clutch disk is primarily designed for the ZF WG94 transmission series. Based on its construction and dimensions, it is also compatible with the following ZF models: WG180, WG200, WG210, and WG240 series transmissions used in heavy-duty commercial vehicles and off-road equipment. Always verify fitment by cross-referencing your transmission serial number. The disk interfaces directly with the CYLINDRICAL PIN for alignment and is identified by the TYPE PLATE on the transmission housing.
