ZF 4660.371.003 DISC CARRIER for WG92/WG98 | OEM Genuine Part

Genuine ZF DISC CARRIER (Part No. 4660.371.003). This part fits: 4 WG 92, 4 WG 98, 4 WG 98 PS, WG 92, WG 98 and 1 more models. Found in: Clutch, Coupling. Also referenced as: 4660371003 / 4660.371.003 / 4660 371 003.

Overview

The ZF 4660.371.003 DISC CARRIER is a critical internal component engineered for the WG92 and WG98 series transmissions. This genuine OEM part functions as the primary 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 gear train assembly, the disc carrier interfaces directly with the 4660101017: TRANSMISSION HOUSING and the 4660301054: HOUSING II to maintain structural integrity during high-stress operations. The SKU 4660.371.003 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged units in off-highway vehicles, construction equipment, and marine drivelines.

Symptoms of Failure

When the disc carrier begins to degrade, operators often notice specific performance declines. Intermittent gear slipping under load is a primary indicator, as worn carrier splines fail to secure the clutch discs. Metallic grinding noises during shifting suggest the carrier has developed cracks or excessive play. Contaminated transmission fluid with metallic debris points to carrier surface wear, while erratic engagement delays in forward or reverse gears signal that the carrier’s alignment bores have fatigued. Addressing these symptoms early prevents catastrophic damage to the 0631306174: CYLINDRICAL PIN and adjacent components.

Compatibility

This disc carrier is specifically validated for the ZF WG92 and WG98 transmission families. Based on its spline count and carrier geometry, it also fits select variants of the WG180, WG200, and WG250 series used in heavy-duty wheel loaders and graders. The part integrates with the 0769123894: TYPE PLATE for correct identification during rebuilds. Always verify your transmission’s serial number against ZF’s cross-reference to ensure proper fitment, as carrier depth tolerances vary between WG92 and WG98 sub-models.
