Overview
The ZF 4642.103.044 OUTPUT for WG150 is a critical driveline component engineered to transfer torque from the transmission’s planetary gearset to the output shaft. This OEM genuine part sits at the rear of the WG 150 series housing, directly interfacing with the flange that connects to the driveshaft. The SKU 4642.103.044 is precision-machined to maintain concentricity and load-bearing capacity under high-stress industrial applications. When paired with a robust TRANSMISSION HOUSING, this output assembly ensures minimal power loss and consistent rotational stability.
Symptoms of Failure
- Oil seepage around the rear seal area: A worn 4642.103.044 output often causes transmission fluid to leak past the seal, leaving visible drips under the vehicle or equipment.
- Vibration or driveline shudder during acceleration: Degraded splines or bearing surfaces on this output create irregular rotation, felt as a rhythmic shake through the chassis.
- Intermittent gear engagement or slipping: When the output’s mating surface wears, torque transfer becomes inconsistent, leading to delayed or rough shifts in the WG150.
- Metallic debris in the transmission fluid: Flaking material from a failing output can contaminate the oil, often detected during routine filter changes.

Compatibility
This output is primarily designed for the ZF WG 150 series, but it also fits select variants of the WG180 and WG200 transmissions when used with the correct adapter. Always verify spline engagement with the corresponding TRANSMISSION HOUSING to ensure proper alignment. For identification, cross-reference the TYPE PLATE on your unit, and secure the assembly using a GROOVED STUD for vibration resistance.
