Overview
The ZF 5838.300.313 OUTER CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 powershift transmissions. This OEM genuine part resides within the clutch pack assembly, where it transfers torque from the rotating drum to the hub under hydraulic pressure. When engaged, the outer clutch disk locks specific planetary gear sets, enabling smooth directional shifts and load-holding capability. The SKU 5838.300.313 is precision-machined to ZF’s original tolerances, ensuring consistent clamping force and heat dissipation during high-torque operations in construction and agricultural machinery.
Symptoms of Failure
- Transmission gear slippage under load: Worn friction material on the 5838.300.313 outer clutch disk causes the clutch pack to lose clamping force, resulting in RPM flare during acceleration or uphill operation.
- Delayed or harsh engagement: As the disk surface degrades, hydraulic pressure cannot fully lock the clutch, leading to a noticeable lag when shifting from neutral to drive or reverse.
- Burnt transmission fluid odor: Excessive heat from a slipping outer clutch disk oxidizes the ATF, producing a distinct burnt smell and darkening the fluid color.
- Metal debris in oil pan: Advanced wear of the friction lining can shed particles that contaminate the hydraulic system, often found during routine filter inspections.

Compatibility
This outer clutch disk is specifically designed for ZF WG series transmissions, including the WG100, WG130, and WG131 models. It is also compatible with select variants of the WG180 and WG200 when used in the forward clutch pack position. Always verify your transmission serial number against ZF’s parts catalog before installation. The disk works in conjunction with the 5838022003: REAR AXLE and the 5838109001: DIFFERENTIAL to complete the driveline assembly. For proper end-play adjustment, pair this disk with a 0750117075: TAPER ROLLER BEARING and ensure the 5838300128: DIFFERENTIAL HOUSING is free of scoring.
