ZF 4660.373.005 DISC CARRIER for WG92/WG98 | OEM Genuine Part

Genuine ZF DISC CARRIER (Part No. 4660.373.005). 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: 4660373005 / 4660.373.005 / 4660 373 005.

Overview

The ZF 4660.373.005 Disc Carrier is a critical internal component engineered for the WG92 and WG98 transmission series. This genuine OEM part functions as the primary mounting hub for the clutch disc pack, ensuring precise alignment and torque transfer within the planetary gearset. Located in the central rotating assembly, the disc carrier interfaces directly with the TRANSMISSION HOUSING and the HOUSING II to maintain proper clutch pack clearance. The SKU 4660.373.005 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in heavy-duty industrial applications.

Symptoms of Failure

When the 4660.373.005 disc carrier wears out, operators typically notice these specific failure modes:

  • Erratic gear engagement or slipping – Worn carrier splines cause the clutch discs to misalign, leading to delayed or incomplete shifts under load.
  • Metallic grinding noise from the transmission housing – Excessive play in the carrier allows the disc pack to contact the TRANSMISSION HOUSING, producing a distinct grinding sound during operation.
  • Oil contamination with metallic debris – Flaking material from a fatigued carrier enters the hydraulic circuit, often clogging the SUCTION TUBE and reducing lubrication flow.
  • Transmission overheating – A damaged carrier increases friction within the clutch pack, generating excess heat that can warp adjacent components like the HOUSING II.
