Overview
The ZF 4660.372.002 DISC CARRIER is a critical internal component engineered for the WG92 and WG98 transmission series. This genuine OEM part serves as the central hub that houses and aligns the clutch disc packs, ensuring precise torque transfer and smooth gear engagement. Positioned within the main gear train assembly, the disc carrier interfaces directly with the 4660101017: TRANSMISSION HOUSING to maintain correct axial clearance. The SKU 4660.372.002 is manufactured to ZF’s exacting tolerances, guaranteeing reliable performance under heavy-duty industrial loads. Without this carrier, the clutch discs cannot maintain proper spacing, leading to drivetrain inefficiency.
Symptoms of Failure
When the ZF 4660.372.002 disc carrier wears or cracks, operators often notice hard shifting between gears due to misaligned clutch packs. A second common symptom is intermittent gear slipping under load, particularly during uphill hauling or sudden acceleration. Third, metallic grinding noises from the transmission housing indicate the carrier splines have worn, allowing the discs to chatter. Finally, contaminated transmission oil with fine metal particles signals that the carrier surface is degrading, which can damage the 4660301054: HOUSING II if left unaddressed.

Compatibility
This disc carrier is specifically designed for the ZF WG92 and WG98 series, but it also fits select WG180 and WG200 models that share the same clutch pack architecture. The part is compatible with transmissions used in construction loaders, agricultural tractors, and industrial forklifts. Always verify the carrier spline count against your existing unit. When replacing, inspect the 0631306174: CYLINDRICAL PIN for wear, as it secures the carrier to the shaft. Additionally, ensure the 0769123894: TYPE PLATE matches your transmission model for correct identification.
