Overview
The ZF 0735.371.862 RODAMIENTO DE RODILLOS CÓNICOS is a precision-engineered tapered roller bearing designed specifically for the ZF WG260 powershift transmission. This OEM original component sits within the transmission’s output shaft assembly, where it manages axial and radial loads generated during heavy-duty construction operations. As a critical wear item, the SKU 0735.371.862 ensures smooth rotational motion and proper gear alignment, directly influencing torque transfer efficiency. When paired with a robust TRANSMISSION HOUSING, this bearing maintains the structural integrity required for demanding earthmoving and material handling applications.
Symptoms of Failure
- Excessive axial play or shaft wobble: A worn 0735.371.862 bearing allows the output shaft to shift, causing misalignment in the gear train. Operators often notice this as a “clunking” sensation during directional changes.
- Metallic grinding noise under load: When the tapered rollers or raceways degrade, a distinct grinding sound emerges, particularly when the WG260 transmission is under heavy torque. This is a classic sign of bearing fatigue.
- Oil contamination with metallic particles: Flaking or spalling of the bearing surfaces introduces fine metal shavings into the transmission fluid. Inspecting the oil filter or drain plug for glitter-like debris is a reliable diagnostic step.
- Increased operating temperature: Friction from a failing roller bearing generates excess heat, which can be detected near the output housing. This symptom often precedes catastrophic failure if ignored.

Compatibility
This tapered roller bearing is engineered for the ZF WG260 transmission series, commonly found in construction machinery such as wheel loaders, graders, and compactors. Based on its design and load characteristics, the 0735.371.862 may also be compatible with the WG180 and WG200 models, though cross-referencing with the specific transmission serial number is recommended. The bearing integrates directly with the HOUSING assembly, which must be free of cracks or distortion for proper fitment. Secure installation requires using the correct HEXAGON SCREW and CAP SCREW torqued to factory specifications to prevent preload loss.
