ZF 0735.301.801 TAPER ROLLER BEARING for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0735.301.801 TAPER ROLLER BEARING is a precision-engineered component designed to manage axial and radial loads within the planetary gear sets of ZF WG series transmissions. Specifically positioned in the output shaft assembly, this OEM genuine part ensures smooth rotational motion and correct gear alignment under high torque conditions. The SKU 0735.301.801 is a direct replacement for the factory-installed bearing, critical for maintaining drivetrain integrity. When paired with the 2094101012: TRANSMISSION HOUSING, this bearing supports the main shaft, while the 2094301036: HOUSING provides the necessary mounting bore tolerance for long service life.

Symptoms of Failure

• Growling or rumbling noise during gear engagement: Worn rollers create uneven contact, producing a low-frequency hum that intensifies under load, often mistaken for gear noise.
• Excessive axial shaft play: As the tapered rollers degrade, the output shaft develops noticeable end float, leading to imprecise shifting and vibration in the 2094298057: HOUSING.
• Metallic debris in transmission fluid: Flaking or spalling of the bearing raceways contaminates the oil, visible as glitter-like particles during drain intervals.
• Oil seepage near the output flange: Bearing wear increases internal clearance, allowing lubricant to bypass the seal and leak past the 2094301071: COVER.

Technical Specifications

Compatibility

This taper roller bearing is engineered for ZF WG100, WG130, and WG131 transmission models. It is also a direct fit for the WG180 and WG200 series when used in the output planetary carrier position. Always verify the housing bore condition in the 2094301036: HOUSING before installation. For complete rebuilds, inspect the 2094101012: TRANSMISSION HOUSING for cracks or wear that could affect bearing alignment.
