Overview
The ZF 4616.105.413 OUTPUT for WG65 is a critical drivetrain component engineered to transfer rotational force from the transmission’s planetary gearset to the output shaft. Positioned at the rear of the WG 65 Series housing, this OEM genuine part ensures precise torque delivery and minimal power loss under heavy-duty loads. The SKU 4616.105.413 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged outputs in off-highway and industrial applications. When paired with a compatible 4616203017: OUTPUT FLANGE, this assembly maintains alignment and reduces vibration during high-torque operation.
Symptoms of Failure
- Oil leaks near the output seal: A degraded 4616.105.413 output can cause fluid to seep past the seal, leading to low transmission fluid levels and overheating.
- Gear slipping under load: Worn splines or bearing surfaces on this output prevent consistent engagement, resulting in intermittent power loss during acceleration or climbing.
- Unusual whining or grinding noises: As the output wears, metal-on-metal contact generates audible noise from the rear of the transmission, especially at low speeds.
- Excessive end-play in the output shaft: A failing output allows axial movement, which can damage the 4616101117: TRANSMISSION HOUSING and adjacent bearings over time.
