ZF 0750.117.057 TAPER ROLLER BEARING for WG200 | OEM Genuine Part

Overview

The ZF 0750.117.057 TAPER ROLLER BEARING is a critical rotational support component engineered specifically for the WG 200 Series transmission. This OEM genuine part sits within the countershaft or output shaft assembly, where it manages combined axial and radial loads generated during gear engagement. Designed to maintain precise shaft alignment under heavy torque conditions, the 0750.117.057 bearing ensures smooth power transfer and reduces frictional wear inside the gearbox. When paired with a properly sealed TRANSMISSION HOUSING, this bearing forms the backbone of the drivetrain’s load-bearing architecture.

Symptoms of Failure

• Growling or rumbling noise during acceleration: Worn tapered rollers produce a low-frequency metallic sound, especially when the transmission is under load. This often signals that the bearing raceways have developed pitting or spalling.
• Excessive shaft endplay or gear misalignment: As the 0750.117.057 loses its preload, the output shaft can shift axially, causing gears to skip or engage roughly. This symptom is frequently misdiagnosed as a synchronizer issue.
• Metallic debris in transmission oil: Flakes or silver particles found during an oil change indicate the bearing’s hardened steel surfaces are deteriorating. If ignored, fragments can damage the HOUSING bore and adjacent gear teeth.
• Oil seepage near the shaft seal area: A failing bearing allows shaft wobble, which compromises the sealing lip. This leads to gradual oil loss around the output flange.

Technical Specifications

Compatibility

This taper roller bearing is a direct OEM replacement for the following ZF transmission models: WG180, WG200, WG210, and certain early-build WG250 units. It is specifically designed for the countershaft rear position in the WG200 series. Always verify the bearing’s orientation and shimming requirements when installing. For proper assembly, ensure the SCREW PLUG is torqued to specification and that the OIL LEVEL GAGE indicates correct fluid height before operation.
