ZF 4661.276.004 CLUTCH for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.276.004 CLUTCH is a critical torque-transfer component engineered specifically for the WG 90 and WG 94 series transmissions. Positioned within the planetary gear set assembly, this OEM genuine part manages the engagement and disengagement of power flow between the input shaft and the intermediate housing. The SKU 4661.276.004 ensures precise hydraulic actuation, allowing smooth gear changes under heavy load conditions. Without this clutch pack, the transmission cannot modulate torque effectively, leading to driveline inefficiency. This part is manufactured to ZF’s original specifications, guaranteeing a direct fit and long service life in industrial applications such as construction vehicles and material handlers.

Symptoms of Failure

When the 4661.276.004 clutch begins to wear, operators often notice delayed engagement when shifting from neutral to drive, a common long-tail search query among fleet managers. Another frequent issue is intermittent gear slipping under moderate to heavy load, which manifests as a sudden loss of power during acceleration. Contaminated transmission fluid with metallic debris is a third symptom, indicating that the clutch friction material is breaking down internally. Finally, erratic shift patterns or harsh engagement can occur when the clutch piston seals fail, causing inconsistent hydraulic pressure. Addressing these symptoms early prevents damage to the CONTROL UNIT and surrounding components.

Technical Specifications

Compatibility

This clutch is primarily designed for the ZF WG 90 and WG 94 transmission series, which are widely used in off-highway vehicles and mobile cranes. It also fits the WG 180 and WG 200 models when used in conjunction with the correct HOUSING assembly. For WG 94 applications, the 4661.276.004 clutch interfaces directly with the HOUSING (part 4661301096) and requires the LOOSE PARTS kit (4656183202) for proper installation. Always verify your transmission model tag before ordering, as variations exist between early and late production runs.
