ZF 0501.342.428 OUTER CLUTCH DISK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.342.428 OUTER CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 automatic transmission series. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating elements during gear shifts. As a steel-backed friction plate, it engages with the inner clutch hub to lock planetary gear sets, enabling smooth power flow through the driveline. The SKU 0501.342.428 is precision-machined to ZF’s exacting tolerances, ensuring consistent clamping force and heat dissipation under heavy-duty industrial loads. When paired with the 4699101153: HOUSING and 4699301250: HOUSING, this disk maintains proper alignment within the clutch drum, preventing axial play that could compromise shift quality.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn friction material on the outer clutch disk causes slipping, leading to a noticeable lag when shifting from neutral to drive or reverse. This symptom often triggers transmission overheating warnings.
• Burning smell from transmission fluid: As the disk loses its friction coefficient, excessive heat builds up, oxidizing the ATF and producing a distinct burnt odor. This is a common long-tail search query for “ZF transmission burning smell repair.”
• Erratic shift patterns under load: When the 0501.342.428 disk fails to hold torque, the transmission may hunt between gears or exhibit flare-ups during acceleration. This is frequently misdiagnosed as a valve body issue.
• Metallic debris in the oil pan: Advanced wear sheds friction material and steel particles, which can clog the filter and damage the 0636101411: CAP SCREW securing the clutch drum assembly.

Technical Specifications

Compatibility

This outer clutch disk is specifically designed for ZF WG100, WG130, and WG131 transmissions, which are commonly found in industrial forklifts, agricultural tractors, and construction loaders. It is not interchangeable with WG180 or WG200 series disks due to differences in spline count and diameter. For proper installation, always inspect the 4699309121: HOUSING COVER for warpage, as a distorted cover can cause premature disk wear. Additionally, verify the condition of the 0631302072: CYLINDRICAL PIN that indexes the clutch pack to the drum.
