ZF 4108.103.090 OUTPUT | OEM Genuine Part

Overview

The ZF 4108.103.090 OUTPUT is a critical driveline component engineered for heavy-duty construction machinery transmissions. This OEM genuine part serves as the primary output flange or hub assembly, transferring rotational torque from the transmission’s planetary gear set directly to the drive shaft. Positioned at the rear of the transmission housing, it ensures precise power delivery under extreme load conditions. The SKU 4108.103.090 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in demanding environments such as wheel loaders, graders, and dump trucks.

Symptoms of Failure

When the ZF 4108.103.090 OUTPUT begins to wear, operators may notice oil seepage around the rear transmission seal, often mistaken for a simple gasket leak. Another common symptom is driveline vibration during acceleration or deceleration, indicating spline wear or hub distortion. You might also experience intermittent gear slipping in higher ranges, as the output component loses its ability to maintain constant engagement with the shaft. Finally, metallic debris in the transmission fluid is a clear sign that this part is shedding material, requiring immediate replacement to prevent cascading damage to the 4108101068: HOUSING and 4108201177: HOUSING.

Technical Specifications

Compatibility

This output component is specifically designed for ZF’s WG180 and WG200 series transmissions, commonly found in construction machinery from manufacturers like Liebherr, Caterpillar, and Volvo. It also fits select variants of the WG150 and WG250 power shift transmissions. Always verify the transmission serial number before ordering, as minor design changes exist between early and late production runs. For proper installation, ensure the mating 0636302056: SCREW PLUG is torqued to factory specifications, and inspect the 4108301304: BEARING COVER for any wear that could affect alignment.
