ZF 0501.327.779 INNER CLUTCH DISK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.327.779 INNER CLUTCH DISK is a precision-engineered friction component designed for the hydraulic clutch pack assembly within ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part sits directly on the clutch hub, transferring torque from the drive plates to the output shaft during gear engagement. The SKU 0501.327.779 ensures exact fitment and material composition for consistent shift quality under heavy-duty industrial loads. When paired with a matching 2095109009 DIFFERENTIAL, this disk maintains proper power distribution across the driveline.

Symptoms of Failure

• Delayed or harsh gear engagement: A worn inner clutch disk causes noticeable hesitation or abrupt grabbing when shifting between forward and reverse ranges.
• Transmission overheating under load: Slipping friction material generates excessive heat, often indicated by rising oil temperature gauges during operation.
• Loss of power to the wheels: The transmission may rev higher than normal without proportional vehicle movement, particularly in higher gear ranges.
• Metallic debris in transmission fluid: Advanced wear releases fine steel particles from the clutch disk hub, visible during routine oil changes or filter inspections.

Technical Specifications

Compatibility

This inner clutch disk is specifically engineered for ZF WG100, WG130, and WG131 series transmissions. These models are commonly found in agricultural tractors, wheel loaders, and industrial forklifts. The part also integrates with the 0750117075 TAPER ROLLER BEARING that supports the clutch drum, and the 2095209037 DIFFERENTIAL which receives torque from the clutch pack. For complete rebuilds, the 2095309059 DIFF.HOUSING provides structural integrity to the final drive assembly.
