ZF 0735.371.923 ROLLER BEARING for WG258/WG261/WG308 | OEM Genuine Part

Overview

The ZF 0735.371.923 ROLLER BEARING is a critical internal component engineered for the WG258, WG261, and WG308 transmission series. This genuine OEM part provides precise radial support for rotating shafts within the gear train, reducing friction and maintaining correct gear alignment under heavy load. The SKU 0735.371.923 sits directly within the main shaft assembly, ensuring smooth power transfer between planetary gear sets. When installed alongside the 4646101162: TRANSMISSION HOUSING, this bearing maintains proper shaft concentricity, which is essential for preventing premature wear on adjacent components.

Symptoms of Failure

• Whining or rumbling noise during gear engagement: A worn 0735.371.923 bearing produces a distinct metallic sound, especially noticeable in lower gears or when decelerating.
• Increased axial play in the output shaft: Excessive end float indicates the roller bearing has lost its internal clearance, leading to misalignment and potential gear clash.
• Oil contamination with metallic debris: Flakes or silver particles in the transmission fluid signal spalling of the bearing raceways, often accompanied by a drop in hydraulic pressure.
• Intermittent gear slipping under load: As the bearing deteriorates, shaft wobble can cause the clutch packs to engage unevenly, resulting in momentary loss of torque.

Technical Specifications

Compatibility

This roller bearing is designed for use in the following ZF transmission models: WG180, WG200, WG258, WG261, WG308, WG310, and WG311 series. It is a direct replacement for the original bearing in the main shaft support position. For proper installation, ensure the 4646301334: HOUSING is free of burrs and the 0636115293: 螺栓 are torqued to factory specifications. After assembly, affix the 0730365125: TYPE PLATE to confirm the rebuild meets OEM standards.
