Overview
The ZF 5838.300.307 OUTER CLUTCH DISK is a precision-engineered friction component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the clutch pack assembly, where it manages torque transfer between rotating shafts during gear shifts. As a critical wear item, the outer clutch disk ensures smooth engagement and disengagement of planetary gear sets. The SKU 5838.300.307 is manufactured to ZF’s exacting tolerances, providing consistent clamping force and heat dissipation under heavy-duty industrial loads. When paired with a matching 5838022003 REAR AXLE, this disk maintains driveline integrity during high-torque operations.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn friction material causes hesitation or jerking when shifting, especially under load.
- Transmission overheating: Slipping disks generate excess heat, leading to burnt fluid smell or thermal damage.
- Loss of power transfer: The transmission may fail to hold gears, causing RPM flare without corresponding vehicle movement.
- Metallic debris in oil pan: Flaking friction material or worn steel plates contaminate the hydraulic system.

Compatibility
This outer clutch disk is specifically engineered for ZF WG100, WG130, and WG131 powershift transmissions. It is also compatible with select WG180 and WG200 variants that share the same clutch pack architecture. The disk works in conjunction with the 5838109001 DIFFERENTIAL and 0750117075 TAPER ROLLER BEARING to distribute torque evenly. For complete assembly, verify fitment with the 5838300128 DIFFERENTIAL HOUSING to ensure proper clearance.
