ZF 4061.313.048 OUTER CLUTCH DISK for WG200 | OEM Genuine Part

Overview

The ZF 4061.313.048 OUTER CLUTCH DISK is a critical friction component engineered for the WG 200 series powershift transmissions. This OEM genuine part sits within the clutch pack assembly, specifically as the outermost steel reaction plate that provides the necessary clamping surface for the friction discs. During gear engagement, hydraulic pressure forces the clutch piston against the pack, and the 4061.313.048 disk absorbs and transmits torque from the input shaft to the planetary gearset. Without this precisely machined outer disk, the clutch pack cannot achieve proper lockup, leading to power loss. The SKU 4061.313.048 is manufactured to ZF’s exacting tolerances to ensure consistent heat dissipation and long service life in heavy-duty off-highway applications.

Symptoms of Failure

• Transmission gear slippage under load: When the outer clutch disk wears thin or develops hot spots, the clutch pack fails to hold torque, causing the transmission to slip when moving heavy loads or climbing grades.
• Delayed or harsh engagement: A warped or glazed 4061.313.048 disk prevents smooth clutch apply, resulting in a noticeable lag when shifting from neutral to drive or reverse.
• Metallic grinding noise from the bell housing: As the disk’s friction material erodes, metal-on-metal contact occurs between the steel plates, producing a distinct grinding sound during gear changes.
• Overheating and burnt transmission fluid: Excessive slippage caused by a worn outer clutch disk generates extreme heat, which oxidizes the ATF and gives off a burnt odor.

Technical Specifications

Compatibility

This outer clutch disk is specifically designed for the ZF WG 200 series transmission family. Based on its physical dimensions and spline configuration, the 4061.313.048 is also compatible with the WG 180 and WG 190 models that share the same clutch pack architecture. It is not suitable for the WG 120 or WG 150 series due to differing clutch diameters. Always verify your transmission’s serial number against ZF’s parts catalog before ordering.

During a full clutch rebuild, this outer disk is installed alongside the 4460115043: HOUSING, which encloses the entire clutch pack. The 4469315012: AXLE DRIVE HOUSING must also be inspected for wear at the same service interval. Proper bearing support is provided by the 0750117406: TAPER ROLLER BEARING and the 0750117802: TAPERED ROLLER BEARING, which should be replaced concurrently to prevent premature clutch disk failure.
