ZF 4660.305.049 DISC CARRIER for WG92/WG98 | OEM Genuine Part

Genuine ZF DISC CARRIER (Part No. 4660.305.049). This part fits: 4 WG 98, 4 WG 98 PS, WG 92, WG 98. Found in: Clutch, Coupling. Also referenced as: 4660305049 / 4660.305.049 / 4660 305 049.

Overview

The ZF 4660.305.049 DISC CARRIER is a critical rotating assembly component engineered for the WG92 and WG98 series transmissions. This OEM genuine part functions as the structural hub that houses and aligns the clutch disc packs, ensuring precise torque transfer and smooth gear engagement under heavy-duty industrial loads. Positioned within the main shaft assembly, the disc carrier interfaces directly with the 4660101015: TRANSMISSION HOUSING to maintain concentricity and reduce vibration. The SKU 4660.305.049 is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification.

Symptoms of Failure

When the ZF 4660.305.049 disc carrier wears out, operators may notice several distinct failure indicators. Delayed or harsh gear engagement occurs when the carrier’s splines or mounting surfaces degrade, preventing proper clutch pack alignment. Metallic grinding noises during shifting often signal that the carrier’s bearing seats have worn, allowing axial play. Transmission oil contamination with metallic debris is a common symptom, as friction between the carrier and the 4660301054: HOUSING II generates fine particles. Intermittent loss of drive power under load can also indicate that the disc carrier is no longer securely retaining the clutch discs.

Compatibility

This disc carrier is designed for ZF WG series transmissions, specifically the WG92 and WG98 models. It is also compatible with the WG180 and WG200 variants where the clutch pack configuration matches the 4660.305.049 spline count and depth. The part integrates with the 0631306174: CYLINDRICAL PIN for precise dowel alignment and the 0769123894: TYPE PLATE for identification. Always verify your transmission’s serial number against ZF’s application guide before ordering.
