ZF 4661.373.014 INNER DISK CARRIER for WG94 | OEM Genuine Part

Overview

The ZF 4661.373.014 INNER DISK CARRIER is a critical rotating component within the WG 94 series transmission. It serves as the structural hub that houses and aligns the friction and steel clutch disks within the clutch pack assembly. Precision-machined to OEM tolerances, this carrier ensures consistent clamping force and torque transfer during gear shifts. As a genuine ZF part, the SKU 4661.373.014 guarantees exact fitment and durability, directly interfacing with the 4661101033 HOUSING and the 4661301096 HOUSING to form the sealed clutch chamber.

Symptoms of Failure

• Erratic or delayed gear engagement: When the inner disk carrier splines wear, the clutch disks cannot seat properly, causing hesitation when shifting from neutral to drive or reverse.
• Transmission slipping under load: A warped or cracked carrier reduces clamping pressure, leading to power loss during acceleration, especially in heavy-duty applications.
• Metallic debris in transmission fluid: Worn carrier surfaces generate fine metal particles, which can be detected during routine oil changes and indicate imminent internal failure.
• Audible grinding or whining noise: Excessive play between the carrier and the 0631306174 CYLINDRICAL PIN creates a distinct mechanical noise during gear rotation.

Technical Specifications

Compatibility

This inner disk carrier is designed for the ZF WG 94 series, which includes the following transmission models: WG94, WG180, WG200, and WG250. It is also commonly used in off-highway and construction equipment transmissions where the WG94 clutch pack configuration is employed. Always verify your transmission serial number before ordering. The carrier works in conjunction with the 0769123894 TYPE PLATE for correct assembly identification.
