ZF 4108.103.170 OUTPUT | OEM Genuine Part

Overview

The ZF 4108.103.170 OUTPUT is a critical driveline component engineered for heavy-duty construction machinery transmissions. This OEM genuine part serves as the final power delivery interface, transferring torque from the transmission’s planetary gearset to the driveshaft or final drive. Positioned at the rear of the main transmission housing, the output assembly ensures smooth rotational force under extreme load conditions. The SKU 4108.103.170 is precision-machined to ZF’s factory tolerances, guaranteeing a direct bolt-on replacement without modification. When paired with the 4108101177: HOUSING and the 4108201312: HOUSING, this output component forms the sealed rear section of the transmission assembly, protecting internal gears from contamination.

Symptoms of Failure

When the ZF 4108.103.170 OUTPUT begins to wear, operators may notice distinct performance issues. Oil leaks around the rear transmission seal are a primary indicator, often caused by a worn output flange or damaged bearing surface. Gear slipping under load—particularly during uphill operation or heavy digging—signals that the output splines have stripped or the shaft has developed torsional fatigue. Vibration or driveline shudder at highway speeds suggests the output bearing has excessive radial play. Finally, metal debris in the transmission fluid during routine oil changes points to internal spalling of the output gear teeth. Addressing these symptoms early prevents catastrophic failure of the 0501225852: OIL LEVEL GAGE and the 0501325471: SEALING RING.

Technical Specifications

Compatibility

This ZF 4108.103.170 OUTPUT is designed for use in ZF’s WG-series powershift transmissions commonly found in wheel loaders, graders, and excavators. It directly fits the WG180 and WG200 transmission models, as well as the WG150 series with a 14-spline output configuration. The part is also compatible with certain 4WG-200 and 5WG-200 variants used in Volvo and Caterpillar machinery. Always verify the output flange bolt pattern matches your existing assembly. For proper installation, ensure the 4108301490: INPUT SHAFT is aligned correctly with the transmission’s clutch pack.
