ZF 4061.313.217 AXLE BEVEL GEAR for WG200 | OEM Genuine Part

Overview

The ZF 4061.313.217 AXLE BEVEL GEAR is a critical power-transfer component engineered specifically for the WG 200 Series transmission. This OEM genuine part sits at the interface of the differential assembly, converting rotational input from the driveshaft into the precise angular motion required to drive the axle. The SKU 4061.313.217 is machined from high-grade alloy steel to withstand extreme torsional loads and continuous heavy-duty operation. It works in direct conjunction with the 4469315012: AXLE DRIVE HOUSING to maintain correct gear mesh alignment and load distribution within the final drive unit.

Symptoms of Failure

• Whining or howling noise during acceleration: A worn bevel gear produces a distinct high-pitched whine that intensifies under load, often indicating uneven tooth contact or pitting on the gear face.
• Vibration in the driveline at highway speeds: As the gear teeth wear asymmetrically, rotational imbalance causes noticeable shuddering through the chassis, particularly between 40-60 mph.
• Metal particles in differential oil: Flaking or spalling of the gear surface contaminates the lubricant with metallic debris, visible during routine oil changes as a silver or bronze sludge.
• Intermittent gear slipping or clunking: Advanced wear leads to excessive backlash, producing a sharp clunk when shifting between forward and reverse, or a momentary loss of torque during hard pulls.

Technical Specifications

Compatibility

This bevel gear is a direct-fit component for the ZF WG 200 Series transmission family. It is primarily used in the WG200, WG210, and WG220 models found in medium-duty trucks, buses, and off-highway equipment. The gear also serves as a replacement in certain WG180 variants where the final drive ratio matches. For proper installation, ensure the 4460115043: HOUSING is inspected for cracks or wear, and always pair with new 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING to guarantee correct preload and gear mesh.
