Overview
The ZF 0750.118.159 ROLLER BEARING is a critical internal component engineered specifically for the WG 65 Series transmission. This OEM genuine part provides precise radial support for rotating shafts within the planetary gear set, ensuring smooth torque transfer and minimizing frictional heat buildup. The SKU 0750.118.159 is designed to maintain proper gear alignment and load distribution under high-stress industrial applications. When installed alongside the 4616105413 OUTPUT and the 4616203017 OUTPUT FLANGE, this bearing ensures the entire drivetrain assembly operates with minimal vibration and extended service life.
Symptoms of Failure
- Whining or grinding noise during gear engagement: A worn 0750.118.159 bearing produces audible metallic sounds, especially when the transmission is under load or during deceleration.
- Excessive axial shaft play: As the roller bearing degrades, noticeable end-play develops in the output shaft, leading to misalignment with the 4616101117 TRANSMISSION HOUSING.
- Oil contamination with metallic debris: Flaking or spalling of the bearing raceways introduces fine metal particles into the transmission fluid, often visible during routine oil changes.
- Intermittent power loss or gear slipping: A failing bearing cannot maintain proper gear mesh, causing momentary loss of torque transfer under heavy loads.

Compatibility
This roller bearing is primarily designed for the ZF WG 65 Series transmission. It is also compatible with the WG 80, WG 120, and WG 150 series models that share the same planetary carrier architecture. The 0750.118.159 bearing interfaces directly with the 0636011038 HEXAGON SCREW used to secure the bearing retainer plate. For complete assembly, always verify shaft diameters and housing bore tolerances against your specific transmission variant.
