ZF 4616.303.169 OUTPUT FLANGE for WG65 | OEM Genuine Part

Overview

The ZF 4616.303.169 OUTPUT FLANGE is a critical driveline component engineered specifically for the WG 65 Series transmission. This OEM genuine part serves as the primary mechanical interface between the transmission output shaft and the propeller shaft or drive axle, transferring rotational torque from the gearbox to the vehicle’s drivetrain. Constructed from high-strength forged steel, the flange ensures precise alignment and secure coupling under heavy load conditions. The SKU 4616.303.169 is machined to exact ZF tolerances, guaranteeing a direct bolt-on replacement without modification. This component works in concert with the 4616105415: OUTPUT assembly and the 4616101094: TRANSMISSION HOUSING to maintain driveline integrity.

Symptoms of Failure

• Transmission fluid seepage at the rear seal: A worn or cracked output flange often damages the rear oil seal, leading to visible drips or wetness around the flange hub. This is a common long-tail search query for “ZF WG65 output flange oil leak.”
• Vibration during acceleration or deceleration: Spline wear or flange distortion causes driveline imbalance, producing rhythmic shaking felt through the chassis at specific RPM ranges.
• Clunking noise when shifting gears: Excessive backlash between the flange splines and the output shaft creates a metallic knock during torque reversals, particularly in stop-and-go operations.
• Premature U-joint or bearing failure: A misaligned flange places angular stress on downstream components, accelerating wear on the 0636011038: HEXAGON SCREW fasteners and adjacent driveline parts.

Technical Specifications

Compatibility

This output flange is primarily designed for the ZF WG65 series transmission. Based on spline geometry and bolt pattern, it is also compatible with the following ZF models: WG180, WG200, WG210, and WG250. The part fits both standard and off-highway variants used in municipal trucks, refuse vehicles, and construction equipment. Always verify the existing 4616303144: OUTPUT FLANGE dimensions before ordering to ensure correct spline engagement.
