ZF 0501.340.873 INNER CLUTCH DISK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.340.873 INNER CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part resides within the clutch pack assembly, where it transfers torque between rotating elements during gear shifts. By providing precise engagement and disengagement, the inner clutch disk ensures smooth power flow and prevents driveline shock. The SKU 0501.340.873 is a direct replacement for worn units, restoring original shift quality and extending transmission service life. This disk works in concert with the 4699101159 HOUSING and the 4699301254 HOUSING to maintain proper hydraulic pressure within the clutch drum.

Symptoms of Failure

• Delayed or harsh gear engagement: When the inner clutch disk wears thin, the clutch pack cannot clamp fully, causing a noticeable lag or a jarring shift when selecting forward or reverse gears.
• Transmission slipping under load: A worn disk loses its friction coefficient, leading to RPM flare without corresponding vehicle acceleration, especially during uphill climbs or heavy towing.
• Contaminated transmission fluid: Friction material shedding from the disk turns the ATF dark brown or black, often accompanied by a burnt odor. This debris can clog the valve body and damage the 4699298049 HOUSING KIT.
• Unusual clutch chatter or vibration: Uneven wear on the inner disk surface creates a shudder during low-speed maneuvers, such as parking lot turns or stop-and-go traffic.

Technical Specifications

Compatibility

This inner clutch disk is specifically designed for ZF WG100, WG130, and WG131 transmissions. It is also compatible with select variants of the WG180 and WG200 series that share the same clutch pack architecture. Always verify your transmission model tag before installation. For complete clutch assembly rebuilds, pair this disk with the 4699309123 HOUSING COVER to ensure proper sealing and alignment.
