ZF 2094.371.012 CLUTCH SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.371.012 CLUTCH SHAFT is a critical rotating component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits torque from the clutch pack to the planetary gearset, acting as the primary interface between the engine’s power input and the gear reduction assembly. The SKU 2094.371.012 is precision-machined to exact ZF tolerances, ensuring concentric rotation and minimal axial play. It sits directly within the TRANSMISSION HOUSING and is supported by the HOUSING assembly, where it engages with the clutch drum splines.

Symptoms of Failure

• Delayed engagement or clutch slip under load: When the shaft splines wear, the clutch pack fails to lock fully, causing hesitation during acceleration or gear changes.
• Metallic grinding noise from the transmission bell housing: Worn bearing journals on the 2094.371.012 shaft create a distinct whirring or grinding sound, especially in neutral or low gear.
• Transmission fluid contamination with metallic debris: As the shaft surface degrades, fine metal particles enter the oil circuit, visible during fluid changes as glitter in the sump.
• Oil leaks near the clutch housing interface: A worn shaft seal surface allows ATF to weep past the SEALING CAP, leaving drips under the vehicle.

Technical Specifications

Compatibility

This clutch shaft is designed exclusively for the ZF WG-series powershift transmissions. Verified compatible models include WG100, WG130, and WG131. It may also fit select WG180 and WG200 variants with identical clutch drum spline geometry, though cross-referencing the GASKET and SHAFT SEAL part numbers is recommended for confirmation. The shaft interfaces with the HOUSING and requires the O-RING for proper sealing during installation.
