Overview
The ZF 2095.313.028 INNER DISK CARRIER is a precision-machined hub component that houses and drives the inner clutch discs within the transmission’s rotating clutch pack assembly. As an OEM genuine part, it ensures positive torque transfer from the clutch discs to the transmission shaft. This carrier is integral to the hydraulic clutch system, and its splined interface must maintain exact tolerances to prevent slippage. The SKU 2095.313.028 is the direct replacement for the original factory unit, designed for demanding construction machinery applications.
Symptoms of Failure
- Intermittent gear slippage under load: Worn splines on the carrier allow the inner clutch discs to rotate slightly, causing the transmission to slip when torque is applied, especially in higher gears.
- Delayed or harsh engagement: A distorted or cracked carrier prevents the clutch pack from fully compressing, leading to a noticeable lag when shifting from neutral to drive or reverse.
- Metallic debris in transmission fluid: As the carrier’s splines wear, fine steel particles contaminate the oil, often visible during routine fluid changes or on the magnetic drain plug.
- Erratic shifting in construction equipment: The carrier’s failure causes inconsistent hydraulic pressure within the clutch drum, resulting in unpredictable shift timing during heavy excavation or loading cycles.

Compatibility
This inner disk carrier is primarily used in ZF WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, telehandlers, and graders. It also fits select variants of the ZF 4WG-200 and 6WG-200 models. Always verify the transmission serial number before installation, as minor spline variations exist between early and late production runs.
When rebuilding the clutch pack, this carrier works in conjunction with the 5838109007: DIFFERENTIAL to distribute torque to the axles. The 0750117075: TAPER ROLLER BEARING supports the carrier’s rotational load, while the 2095209019: DIFFERENTIAL ensures smooth power transfer to the wheels. A 0631329086: SPRING PIN secures the carrier to the shaft, preventing axial movement during operation.
