ZF 4661.372.044 INNER DISK CARRIER for WG90/WG94 | OEM Genuine Part

Overview

The ZF 4661.372.044 INNER DISK CARRIER is a critical rotating component within the clutch pack assembly of WG90 and WG94 series transmissions. This OEM genuine part, identified by SKU 4661.372.044, serves as the structural hub that houses and aligns the friction and steel disks during gear engagement. Positioned directly on the transmission main shaft, it transmits torque from the clutch pack to the planetary gearset. For optimal sealing and alignment, this carrier interfaces directly with the TRANSMISSION HOUSING and the HOUSING assembly, ensuring precise oil flow through the TUBE.

Symptoms of Failure

• Delayed or harsh gear engagement: When the inner disk carrier splines wear, the clutch disks cannot seat properly, causing noticeable hesitation or jarring shifts during acceleration.
• Low transmission oil pressure warnings: Cracks or warpage in the carrier body disrupt internal oil galleries, leading to pressure drops that trigger dashboard alerts.
• Metallic grinding noise from the transmission: A worn carrier allows the disk pack to shift laterally, creating metal-on-metal contact with the CYLINDRICAL PIN guides.
• Torque converter shudder at highway speeds: Inconsistent disk clamping caused by a deformed carrier results in vibration under load, often misdiagnosed as a converter issue.

Technical Specifications

Compatibility

This inner disk carrier is engineered for ZF WG90 and WG94 series transmissions, commonly found in heavy-duty construction equipment and agricultural machinery. Based on the part design and spline configuration, it is also compatible with the following ZF models: WG180, WG200, WG210, and WG250. Always verify the spline count and disk pack thickness against your specific transmission build sheet before installation.
