ZF 4108.103.071 OUTPUT | OEM Genuine Part

Overview

The ZF 4108.103.071 OUTPUT is a critical OEM genuine component engineered for the final drive assembly in heavy-duty construction machinery transmissions. This part serves as the primary power take-off point, transferring rotational force from the gear train to the driveline or auxiliary equipment. Positioned at the rear of the transmission housing, the 4108.103.071 output shaft ensures precise torque delivery under extreme loads. The SKU 4108.103.071 is manufactured to ZF’s original specifications, guaranteeing exact fitment and durability in demanding environments such as excavators, wheel loaders, and graders. When installed alongside the 4108101031: HOUSING, this output component forms a sealed, high-pressure interface that withstands continuous operation.

Symptoms of Failure

• Oil leaks near the output flange: Worn seals or bearing surfaces on the 4108.103.071 allow transmission fluid to escape, leaving puddles under the vehicle. This is often accompanied by a burnt smell from overheating fluid.
• Gear slipping under load: A failing output shaft causes intermittent power loss during acceleration or when climbing grades, as the splines or bearing journals degrade.
• Vibration or driveline shudder: Excessive play in the output bearing results in noticeable shaking through the chassis, especially at highway speeds or during PTO engagement.
• Metallic grinding noises: Internal wear on the output gear teeth produces a distinct grinding sound, indicating imminent catastrophic failure if not addressed.

Technical Specifications

Compatibility

This output shaft is designed for ZF’s WG series powershift transmissions commonly used in construction machinery. It is a direct replacement for models including WG180, WG200, WG210, and WG240. The 4108.103.071 also fits select variants of the ZF 4WG-200 and 6WG-250 series. For proper assembly, ensure the mating 4108303155: HOUSING is inspected for wear. Additional sealing components such as the 0636302015: SCREW PLUG and 0630361037: SEALING CAP must be replaced concurrently to prevent contamination.
