Overview
The ZF 4699.103.114 OUTPUT is a critical OEM genuine component engineered for the rear output section of heavy-duty ZF construction machinery transmissions. This part serves as the primary interface between the transmission housing and the driveline, transferring rotational torque from the planetary gear set to the vehicle’s final drive. Precision-machined to ZF’s exacting tolerances, the 4699.103.114 ensures minimal power loss and reliable engagement under extreme loads. When paired with the 4699101113: HOUSING and the 4699301201: HOUSING, this output component forms a sealed, high-strength assembly that withstands continuous operation in excavators, wheel loaders, and graders.
Symptoms of Failure
- Transmission oil leaks at the rear flange: Worn output seals or bearing surfaces cause fluid to weep around the output shaft, leading to low oil levels and overheating.
- Driveline vibration during acceleration: A damaged 4699.103.114 output can create imbalance, resulting in rhythmic shaking that worsens under load.
- Intermittent gear slipping in high range: When the output spline wears, torque transfer becomes inconsistent, causing the transmission to momentarily lose drive power.
- Metallic debris in the transmission fluid: Spalling or fretting of the output component sheds fine metal particles, which can clog filters and damage downstream planetary gears.

Compatibility
This output component is designed for ZF’s WG series powershift transmissions commonly used in construction machinery. Based on its spline geometry and flange pattern, the 4699.103.114 is compatible with the following models: WG180, WG200, WG211, and WG240. It also fits select variants of the Ecomat 5HP series when used with the appropriate 4699309202: HOUSING COVER. Always verify your transmission’s serial number before ordering.
During installation, the output must be secured using 0636101477: CAP SCREW fasteners torqued to ZF specifications. For complete rebuilds, inspect the mating 4699101113: HOUSING for cracks and replace the 4699301201: HOUSING if bearing bores are worn.
