Overview
The ZF 2094.298.038 INPUT SHAFT is a critical torque-transfer component engineered for the WG100, WG130, and WG131 transmission series. As the primary interface between the engine’s output and the transmission’s planetary gearset, this OEM genuine shaft ensures precise rotational alignment and load distribution under high-stress conditions. The SKU 2094.298.038 is machined from hardened alloy steel to withstand continuous torsional loads, and it directly interfaces with the TRANSMISSION HOUSING (2094101019) to maintain concentricity. Without this shaft, the gear train cannot transfer power, making it a non-negotiable element in any rebuild or overhaul of the WG-series gearbox.
Symptoms of Failure
- Erratic gear engagement or slipping under load: A worn input shaft spline or bearing journal causes the clutch pack to lose positive engagement, leading to delayed shifts or complete torque loss.
- Oil seepage at the front housing interface: When the shaft’s sealing surface becomes scored or pitted, transmission fluid bypasses the SHAFT SEAL (0750111371), resulting in visible drips near the bell housing.
- Vibration or whining noise during acceleration: Bearing race wear on the input shaft produces a cyclical metallic sound that intensifies with RPM, indicating imminent failure of the HOUSING (0899325353) support bore.
- Hard shifting or gear clash: A bent or twisted input shaft alters the gear mesh pattern, causing audible grinding and resistance when moving the selector lever.

Compatibility
This input shaft is specifically designed for the ZF WG100, WG130, and WG131 transmission models. It is also compatible with select WG180 and WG200 variants that share the same front bearing cluster and spline geometry. The shaft must be installed with the HOUSING (2094298058) and COVER (2094301071) to ensure correct axial preload. Always verify the transmission serial number against the OEM parts catalog before ordering, as later WG200 units may use a revised shaft length.
