Overview
The ZF 4108.103.069 OUTPUT is a critical OEM genuine component designed to transfer rotational force from the transmission’s final planetary gearset to the driveline in heavy-duty construction machinery. Positioned at the rear of the transmission housing, this output shaft assembly ensures precise torque delivery under extreme loads. The SKU 4108.103.069 is engineered to ZF’s original specifications, guaranteeing a direct fit and long service life in demanding environments such as wheel loaders, graders, and dozers. When paired with the 4108101112: HOUSING and the 4108201177: HOUSING, this output component forms a sealed, high-torque interface that withstands continuous operation.
Symptoms of Failure
When the ZF 4108.103.069 OUTPUT begins to wear, operators may notice oil seepage around the rear transmission seal, often accompanied by a visible drip after shutdown. Another common failure sign is intermittent gear slipping during forward-to-reverse shifts, caused by worn splines on the output shaft. You might also detect a low-frequency rumbling noise from the transmission tail section, which worsens under load. Finally, vibration through the chassis during acceleration can indicate that the output shaft’s bearing surface has degraded, leading to misalignment. Addressing these symptoms early prevents damage to the 0636302056: SCREW PLUG and the 4108301304: BEARING COVER.

Compatibility
This OEM genuine output shaft is primarily used in ZF WG180, WG200, and WG210 series transmissions found in construction machinery. It also fits select variants of the ZF 4WG-200 and 5WG-210 models, particularly those with a rear PTO option. For accurate fitment, always verify the transmission serial number against the 4108.103.069 part code. The shaft interfaces directly with the 4108306173: GASKET and the 0750110040: SHAFT SEAL to maintain hydraulic pressure integrity.
