ZF 4460.368.318 FLANGE for WG200 | OEM Genuine Part

Overview

The ZF 4460.368.318 FLANGE is a critical driveline component engineered specifically for the WG 200 Series transmission. This OEM genuine part serves as the primary output interface, transferring rotational torque from the transmission housing to the propeller shaft. Positioned at the rear of the gearbox, the flange ensures a secure, vibration-free connection that maintains driveline alignment under heavy loads. The SKU 4460.368.318 is precision-machined to ZF’s exacting tolerances, making it a direct replacement for worn or damaged units in commercial vehicle and industrial powertrain applications.

Symptoms of Failure

• Transmission oil seepage at the rear seal: A worn 4460.368.318 flange often develops surface pitting or spline wear, allowing lubricant to escape past the output shaft seal. This manifests as visible drips or a wet patch beneath the bell housing.
• Driveline vibration during acceleration: When the flange’s pilot bore or bolt holes become elongated, the propeller shaft loses concentric alignment. Operators may notice a rhythmic shudder between 40–60 km/h under load.
• Clunking noise on gear engagement: Excessive backlash from a fatigued flange causes a metallic knock when shifting from neutral to drive or reverse, indicating spline slop between the flange and output shaft.
• Premature u-joint or bearing wear: A distorted flange face misaligns the driveline angles, accelerating wear on downstream components like the AXLE DRIVE and universal joints.

Technical Specifications

Compatibility

This flange is primarily designed for the ZF WG200 series transmission, but it also fits select variants in the WG180 and WG210 families. It is commonly found in ZF Ecolife and Ecomat 2/3/4 series gearboxes used in municipal buses, refuse trucks, and construction equipment. Always verify the output shaft spline count (typically 28 splines) before installation. For proper mounting, pair this flange with the HEXAGON SCREW and WASHER to achieve the correct torque specification of 120 Nm. The assembly also integrates with the CONSOLE and CONSOLE brackets for secure chassis mounting.
