ZF 4644.102.101 INPUT for WG200 | OEM Genuine Part

Overview

The ZF 4644.102.101 INPUT for WG200 is a critical OEM genuine component designed to transfer engine torque directly into the transmission’s planetary gear set. Positioned at the front of the gearbox, this input shaft assembly interfaces with the torque converter and the 4644105424: DISCONNECTION mechanism to ensure smooth power flow during shifting. As a precision-machined part, the SKU 4644.102.101 guarantees exact fitment and durability under high-load conditions, making it essential for maintaining driveline integrity in heavy-duty applications.

Symptoms of Failure

When the ZF 4644.102.101 input shaft begins to wear, operators may notice several distinct failure indicators. Common symptoms include gear slipping under load, where the transmission hesitates or loses power during acceleration. Another frequent issue is oil leaks around the front seal area, often caused by shaft wobble or surface scoring. Additionally, abnormal grinding noises during engagement can signal spline wear, while delayed or harsh shifting may occur if the input shaft’s alignment with the 4644303538: OUTPUT FLANGE is compromised. Addressing these symptoms early prevents cascading damage to the 4644101224: TRANSMISSION HOUSING and other internal assemblies.

Technical Specifications

Compatibility

This input shaft is engineered for the ZF WG 200 Series transmissions, including models such as WG180, WG200, and WG210. It is also compatible with select ZF Ecomat variants that share the same spline geometry and pilot bearing configuration. For proper installation, always pair this part with the correct 0636021036: HEXAGON SCREW kit to secure the shaft to the torque converter hub. Verify your transmission’s serial number against the OEM parts catalog to ensure exact fitment.
