ZF 4061.313.235 INNER CLUTCH DISK for WG200 | OEM Genuine Part

Overview

The ZF 4061.313.235 Inner Clutch Disk is a critical friction component engineered for the WG200 series powershift transmission. This OEM genuine part resides within the clutch pack assembly, where it transfers torque between rotating drums and hubs during gear engagement. Designed to withstand high thermal loads and repetitive hydraulic pressure, the 4061.313.235 ensures precise shift modulation and long service life. As a direct replacement for the original factory component, this SKU maintains the exact frictional characteristics required for smooth power delivery in heavy-duty industrial applications.

Symptoms of Failure

• Delayed or harsh gear engagement – When the inner clutch disk wears thin, hydraulic clamping force cannot fully lock the clutch pack, causing noticeable hesitation or jerky shifts during acceleration.
• Transmission slipping under load – A worn 4061.313.235 loses its coefficient of friction, allowing the clutch to slip when torque is applied, particularly in forward or reverse gears under heavy payloads.
• Burnt transmission fluid odor – Excessive heat generated by a glazed or warped disk degrades the ATF, producing a distinct burnt smell and darkening the fluid color.
• Metallic debris in the oil pan – Advanced wear of the friction material or steel core sheds particles that contaminate the hydraulic system, often visible during routine fluid changes.

Technical Specifications

Compatibility

This inner clutch disk is specifically designed for the ZF WG200 series powershift transmission. It is also compatible with the closely related WG180 and WG190 models that share the same clutch pack architecture. The 4061.313.235 fits both standard and heavy-duty variants of these transmissions used in construction loaders, forklifts, and agricultural tractors. Always verify the clutch pack stack height and spline count against your existing assembly before installation.
