ZF 2093.349.031 INPUT SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2093.349.031 INPUT SHAFT is a precision-machined component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational force from the torque converter directly into the planetary gearset, serving as the primary torque input point within the driveline. The SKU 2093.349.031 is manufactured to ZF’s exacting tolerances to ensure minimal backlash and optimal power flow. When paired with a properly functioning 2095109020: DIFFERENTIAL, this input shaft maintains consistent gear engagement under heavy load conditions.

Symptoms of Failure

• Audible whining or grinding noise during acceleration: Worn splines on the 2093.349.031 cause metal-on-metal contact, producing a high-pitched sound that intensifies with engine RPM.
• Delayed or harsh engagement when shifting from neutral to drive: A damaged input shaft fails to seat properly with the clutch hub, leading to a noticeable lag or jolt during gear selection.
• Vibration through the chassis at highway speeds: Eccentric wear on the shaft’s bearing journals creates imbalance, transmitting tremors through the transmission housing and into the vehicle frame.
• Metallic debris in transmission fluid during service: Flaking or pitting on the shaft surface contaminates the oil, often accompanied by a burnt smell from friction-generated heat.

Technical Specifications

Compatibility

This input shaft is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It also fits select variants of the WG180 and WG200 when used with the correct 0750117075: TAPER ROLLER BEARING for axial support. The 2093.349.031 is not compatible with older WG80 or WG90 units without modification to the input housing. For differential-side applications, the 2095209037: DIFFERENTIAL and 2095309059: DIFF.HOUSING are commonly replaced during the same overhaul procedure.
