ZF 0735.371.867 RODAMIENTO DE RODILLOS para WG250/WG258/WG308 | Pieza Original OEM

Overview

The ZF 0735.371.867 RODAMIENTO DE RODILLOS is a precision-engineered roller bearing designed for the internal planetary gear sets of ZF WG250, WG258, and WG308 construction machinery transmissions. This OEM original component (SKU: 0735.371.867) sits directly on the main shaft assembly, supporting radial loads between the sun gear and planetary carrier. Its primary function is to maintain smooth rotational alignment under extreme torque conditions, directly influencing gear mesh accuracy. When installed correctly with a new TRANSMISSION HOUSING, this bearing ensures minimal friction and extended service life in heavy-duty earthmoving equipment.

Symptoms of Failure

• Low-frequency growling noise during acceleration: Worn rollers create a distinct rumble, especially under load in forward gears. This is a common search query for «ZF transmission bearing noise WG250.»
• Metallic debris in transmission fluid: Flaking or spalling of the bearing raceways introduces fine steel particles into the oil, often detected during routine filter changes.
• Axial shaft play at the output flange: Excessive clearance allows the planetary carrier to shift, causing intermittent gear engagement and harsh shifting in WG258 models.
• Oil seepage near the bearing bore: As the bearing cage degrades, it can damage the adjacent HOUSING seal surface, leading to external leaks.

Technical Specifications

Compatibility

This roller bearing is a direct replacement for the following ZF transmission models used in construction machinery: WG250, WG258, and WG308. It is also compatible with earlier WG180 and WG200 variants when used in the planetary output stage. Always verify the bearing position: it supports the sun gear in the first planetary set. For proper assembly, pair this bearing with a new COVER and secure it using a HEXAGON SCREW torqued to manufacturer specifications.
