Overview
The ZF 0735.410.173 ROLLER BEARING is a critical load-bearing component engineered for the planetary gear sets and main shaft assemblies within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part ensures precise rotational support, reducing friction between the shaft and the 4108101112: HOUSING while maintaining axial alignment under heavy torque loads. As a direct replacement for SKU 0735.410.173, it restores the original clearance tolerances required for smooth power flow through the gear train. When installed alongside the 4108201177: HOUSING, this roller bearing prevents metal-to-metal contact that would otherwise lead to premature transmission failure.
Symptoms of Failure
- Low-frequency growling or rumbling noise from the transmission housing — particularly noticeable during deceleration or when the transmission is under load, indicating spalling on the roller raceways.
- Intermittent gear engagement hesitation or slipping — caused by increased radial play that misaligns the planetary carrier, leading to delayed clutch pack engagement.
- Metallic debris in the transmission oil pan or on the magnetic drain plug — a direct sign that the roller bearing cage or rollers are fragmenting, which can obstruct oil passages.
- Vibration through the vehicle chassis at highway speeds — resulting from uneven roller wear that creates a cyclical imbalance in the rotating assembly.

Compatibility
This roller bearing is specifically designed for the ZF WG100, WG130, and WG131 series transmissions. It is also compatible with select variants of the WG180 and WG200 models where the main shaft bearing journal dimensions match. Always verify the bearing seat dimensions in your 4108301304: BEARING COVER before installation. For transmissions using the 0636302056: SCREW PLUG in the lubrication gallery, this bearing ensures proper oil flow to the roller elements.
