Overview
The ZF 0750.119.098 ROLLER SET is a precision-engineered bearing assembly designed for the WG 150 Series transmissions. This OEM genuine part plays a critical role in supporting planetary gear sets and reducing rotational friction within the gear train. Located within the main shaft assembly, the roller set ensures smooth power transfer and load distribution across the transmission’s internal components. The SKU 0750.119.098 is a direct replacement for worn units, restoring original factory tolerances and preventing premature wear on adjacent parts such as the 4642101108: TRANSMISSION HOUSING and the 4642301208: TRANSMISSION HOUSING.
Symptoms of Failure
- Gear slipping under load: Worn rollers lose their ability to maintain consistent gear engagement, causing intermittent power loss during acceleration or uphill operation.
- Metallic grinding or whining noise: Degraded roller surfaces create abnormal contact with raceways, producing audible noise from the transmission housing during neutral or drive cycles.
- Oil contamination with metallic debris: Flaking or spalling of roller material introduces fine metal particles into the transmission fluid, often visible during oil changes or filter inspections.
- Increased operating temperature: Excessive friction from a failing roller set generates heat, potentially triggering thermal warnings or causing fluid breakdown.

Compatibility
This roller set is specifically engineered for the ZF WG 150 Series transmission family. Based on its design and load characteristics, it is also compatible with the following models: WG 150, WG 180, and WG 200. It may be used in select WG 120 variants where the planetary carrier dimensions match. Always verify the 0730365125: TYPE PLATE on your transmission to confirm part interchangeability. For secure mounting, the 0631311009: GROOVED STUD is often replaced concurrently during roller set service.
