Overview
The ZF 4461.371.043 Axle Bevel Gear is a precision-engineered component designed for the final drive assembly of ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part transfers rotational power from the differential to the axle shafts, ensuring smooth torque delivery and load distribution in heavy-duty industrial vehicles. Located within the axle housing, the bevel gear meshes with the ring gear to convert driveline rotation into wheel movement. The SKU 4461.371.043 is manufactured to exacting ZF tolerances, using case-hardened alloy steel for maximum fatigue resistance under high-stress conditions. Proper installation requires careful alignment with the 4143101009: HOUSING and 4143301025: HOUSING to maintain gear mesh integrity.
Symptoms of Failure
- Whining or howling noise from axle during acceleration: Worn gear teeth produce a distinct high-pitched sound that intensifies under load, often indicating pitting or spalling on the bevel gear surface.
- Vibration in the driveline at steady speeds: As the gear profile degrades, uneven tooth contact creates cyclical vibrations felt through the chassis or steering wheel.
- Metal particles in transmission fluid: Flaking or chipped gear material contaminates the lubricant, visible as glitter or sludge during oil changes.
- Intermittent loss of drive or slipping: Advanced wear can cause the bevel gear to skip teeth, resulting in momentary power loss during low-speed maneuvers or hill climbs.

Compatibility
This axle bevel gear is specifically engineered for ZF WG-series transmissions used in agricultural tractors, construction loaders, and industrial forklifts. Verified compatible models include:
- ZF WG100 (all variants)
- ZF WG130 (including WG130/2)
- ZF WG131 (early and late production)
- ZF WG180 (with adapter housing modifications)
- ZF WG200 (limited compatibility, verify spline count)
During installation, always replace the 0634313603: O-RING and 4475280018: SCREW PLUG to prevent lubricant leaks. The gear must be paired with a matching ring gear (not included) to maintain proper backlash of 0.15-0.25 mm.
