ZF 4646.103.409 OUTPUT for WG250 | OEM Genuine Part

Overview

The ZF 4646.103.409 OUTPUT for WG250 is a critical drivetrain component engineered to transfer torque from the transmission’s planetary gear set to the output shaft. Positioned at the rear of the ZF WG250 series gearbox, this OEM genuine part ensures precise rotational alignment and load distribution under high-stress industrial conditions. The SKU 4646.103.409 is manufactured to ZF’s original specifications, guaranteeing a direct fit and long service life. When paired with the TRANSMISSION HOUSING (4646101028), this output assembly forms the backbone of the gearbox’s power delivery system.

Symptoms of Failure

When the ZF 4646.103.409 OUTPUT begins to wear, operators may notice these specific failure indicators:

• Oil leaks near the rear output seal – Worn output components often cause fluid to seep past the seal, leading to low transmission fluid levels and overheating.
• Gear slipping under load – A degraded output hub can cause intermittent torque loss, especially during heavy lifting or climbing.
• Vibration or whining noise from the driveline – Misalignment or bearing wear in the output assembly generates audible noise and vibration that worsens with speed.
• Difficulty engaging reverse or low gears – Damaged output splines may prevent smooth engagement, resulting in harsh shifting or complete gear lockout.

Technical Specifications

Compatibility

This output component is specifically designed for the ZF WG250 series, but it also fits select models in the WG180, WG200, and WG240 families due to shared output flange dimensions. Always verify spline count and pilot bore diameter before installation. For complete assembly, the HOUSING (4646301095) and COVER (4646301087) must be installed with the correct HEXAGON SCREW (0636015304) to prevent oil leaks and maintain structural integrity.
