ZF 4061.313.204 DIFFERENTIAL BEVEL GEAR for WG200 | OEM Genuine Part

Overview

The ZF 4061.313.204 DIFFERENTIAL BEVEL GEAR is a critical power transfer component engineered specifically for the WG 200 Series transmission family. This OEM genuine part sits at the heart of the differential assembly, where it meshes with the ring gear to convert rotational input from the driveshaft into the torque required for axle output. Designed to withstand high axial and radial loads, the bevel gear ensures smooth, efficient power distribution under demanding industrial conditions. The SKU 4061.313.204 is precision-machined to ZF’s exacting tolerances, guaranteeing a direct fit and long service life when paired with the 4460115043: HOUSING and the 4469315012: AXLE DRIVE HOUSING.

Symptoms of Failure

• Whining or howling noise from the differential: A worn 4061.313.204 bevel gear often produces a distinct, high-pitched whine during acceleration or deceleration, indicating improper tooth contact or pitting.
• Vibration in the driveline under load: As the gear surface degrades, uneven wear patterns cause noticeable vibrations that can be felt through the chassis, especially at highway speeds.
• Oil leaks near the differential housing: Excessive gear play can stress the 0734319337: SHAFT SEAL, leading to lubricant seepage around the axle drive housing.
• Intermittent gear slipping or clunking: Advanced wear or chipped teeth result in sudden torque loss or a metallic clunk when engaging the drivetrain, signaling imminent failure.

Technical Specifications

Compatibility

This differential bevel gear is a direct OEM replacement for the ZF WG 200 Series transmissions, including models WG180, WG200, and WG210. It is also compatible with select ZF off-highway and industrial drivelines that share the same differential carrier design. For proper installation, always pair this gear with the 0750117406: TAPER ROLLER BEARING and the 0750117802: TAPERED ROLLER BEARING to maintain correct preload and gear mesh alignment.
