ZF 4651.103.003 OUTPUT for WG100 | OEM Genuine Part

Overview

The ZF 4651.103.003 OUTPUT is a critical driveline component engineered specifically for the WG 100 Series transmission family. This OEM genuine part serves as the primary power take-off interface, transferring rotational force from the transmission’s planetary gear set to the output shaft and downstream equipment. Positioned at the rear of the transmission housing, the 4651.103.003 ensures precise torque delivery and alignment under heavy industrial loads. When installed alongside a robust TRANSMISSION HOUSING (4651101006), this output assembly maintains structural integrity and reduces vibration. The SKU 4651.103.003 is factory-machined to ZF’s exacting tolerances, guaranteeing a direct fit without modification.

Symptoms of Failure

When the ZF 4651.103.003 OUTPUT begins to wear, operators may notice distinct performance issues. Oil seepage around the output flange is a common early indicator, often caused by a degraded seal or housing crack. Intermittent gear slipping under load occurs when the output splines lose their interference fit, leading to erratic power delivery. Unusual metallic grinding noises during acceleration or deceleration signal advanced wear on the output bearing race. Additionally, excessive axial play in the output shaft can cause misalignment, accelerating damage to the HOUSING (4651301034) and adjacent components.

Technical Specifications

Compatibility

This output component is primarily designed for the WG 100 Series transmissions, including models WG100, WG120, and WG150. It also fits select variants of the WG180 and WG200 series when used with the correct O-RING (0634303928) and HOUSING (4651301013). For WG250 and WG300 applications, verify output flange dimensions before installation. Always replace the mating seal and gasket set during service to prevent premature failure.
