ZF 4644.103.058 OUTPUT for WG180 | OEM Genuine Part

Overview

The ZF 4644.103.058 OUTPUT for WG180 is a critical OEM genuine component designed to transfer rotational force from the transmission’s planetary gearset to the driveline. Positioned at the rear of the gearbox, this output shaft assembly ensures smooth power delivery and maintains proper alignment within the housing. The SKU 4644.103.058 is precision-machined to ZF’s exacting tolerances, making it a direct replacement for worn units in heavy-duty applications. When installed alongside the 4644105475: DISCONNECTION mechanism, it facilitates reliable torque interruption during clutch shifts. This part is also paired with the 4642303097: OUTPUT FLANGE to secure the driveshaft connection, and it is mounted within the 4644101134: TRANSMISSION HOUSING for structural integrity. All fastening is completed using the 0636020211: HEXAGON SCREW to ensure vibration resistance.

Symptoms of Failure

When the ZF 4644.103.058 output shaft begins to wear, operators may notice several distinct failure indicators. Oil leaks around the rear seal area are common, often caused by shaft scoring or bearing play. Gear slipping under load occurs when the splines on the output shaft lose their interference fit with the clutch pack. Vibration during acceleration typically signals bearing fatigue or shaft imbalance. Finally, erratic shifting or delayed engagement can result from worn splines that fail to transmit torque consistently. These symptoms often prompt replacement of the entire output assembly to avoid driveline damage.

Technical Specifications

Compatibility

This output shaft is engineered primarily for the ZF WG180 series transmissions, commonly found in medium-duty trucks and construction equipment. It is also compatible with the WG200 and WG150 models that share the same spline geometry and bearing journal dimensions. The part fits both standard and heavy-duty variants, including the WG180-1 and WG180-2. Always verify the spline count and shaft length against your existing unit before installation. For transmissions requiring a different output configuration, consider the 4644301349: HOUSING or the 0730365125: TYPE PLATE for identification.
