Overview
The ZF 0735.371.862 TAPERED ROLLER BEARING is a precision-engineered OEM genuine component designed specifically for the WG260 series and related heavy-duty transmission families. This bearing sits within the main shaft assembly, managing axial and radial loads during gear shifts and sustained operation. Its tapered roller geometry ensures smooth torque transfer and reduces friction between rotating elements. As a critical wear item, the SKU 0735.371.862 directly supports the structural integrity of the TRANSMISSION HOUSING and the HOUSING assembly, preventing misalignment under high-stress conditions.
Symptoms of Failure
- Audible grinding or rumbling noise during gear engagement: Worn tapered rollers create metallic chatter, especially under load, signaling imminent bearing collapse.
- Excessive axial play in the output shaft: A failing 0735.371.862 allows lateral movement, leading to gear misalignment and erratic shifting patterns.
- Oil contamination with metallic debris: Flaking from the bearing raceway mixes with transmission fluid, visible as silver particles on the dipstick or filter.
- Vibration through the driveline at highway speeds: Degraded rollers induce harmonic resonance, felt as a low-frequency shudder in the chassis.

Compatibility
This OEM genuine bearing is engineered for ZF WG-series transmissions, including the WG180, WG200, WG251, WG258, WG260, WG261, WG308, and WG311 models. It is a direct replacement in the main shaft bearing pack for the WG260 series, where it interfaces with the HEXAGON SCREW and CAP SCREW fasteners that secure the bearing retainer. Always verify fitment against your transmission’s serial number before installation.
