ZF 4660.373.013 DISC CARRIER for WG92/WG98 | OEM Genuine Part

Overview

The ZF 4660.373.013 DISC CARRIER is a critical internal component engineered for the WG92 and WG98 series transmissions. This genuine OEM 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 gear train assembly, the disc carrier directly interfaces with the 4950101004: HOUSING and the 4950301018: HOUSING I to maintain concentric alignment. The SKU 4660.373.013 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged carriers in high-cycle applications.

Symptoms of Failure

• Erratic gear engagement or slipping: A worn disc carrier can cause uneven clutch pack pressure, leading to delayed or incomplete gear shifts, especially under load.
• Metallic grinding noises from the transmission: Excessive play in the carrier splines or bearing surfaces produces audible grinding or rattling during operation.
• Oil contamination with metallic debris: As the carrier wears, small metal particles shed into the transmission fluid, often visible during oil changes or when inspecting the 0734309932: SHAFT SEAL area.
• Vibration during power take-off (PTO) operation: A distorted carrier can induce driveline vibration, particularly when the transmission is under high torque in WG92 or WG98 models.

Technical Specifications

Compatibility

This disc carrier is specifically designed for ZF WG92 and WG98 series transmissions. It is also compatible with the WG180, WG200, and select WG210 variants that share the same clutch pack architecture. The part integrates directly with the 4660101023: TRANSMISSION HOUSING and requires proper alignment with the 4660301058: HOUSING for correct oil flow. Always verify your transmission’s serial number against ZF’s compatibility charts before installation.
