ZF 4616.328.012 SHAFT for WG65 | OEM Genuine Part

Overview

The ZF 4616.328.012 SHAFT is a critical internal component engineered specifically for the WG 65 Series transmission. This genuine OEM part functions as the primary torque transfer element within the planetary gear set, ensuring smooth power delivery from the engine to the driveline. Positioned between the 4616105402: OUTPUT assembly and the 4005303005: OUTPUT FLANGE, this shaft maintains precise rotational alignment under heavy loads. The SKU 4616.328.012 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit without modification.

Symptoms of Failure

• Transmission gear slipping under load: When the 4616.328.012 shaft wears, splines can strip, causing intermittent power loss during acceleration or climbing.
• Metallic grinding noise from the bell housing: A worn shaft bearing surface produces a distinct whining or grinding sound, especially in neutral or low gear.
• Oil leaks near the output flange area: Shaft seal surface degradation leads to fluid seepage around the 0636011038: HEXAGON SCREW mounting points, visible as drips under the vehicle.
• Vibration during gear changes: Excessive shaft runout causes driveline shudder, particularly when shifting between 2nd and 3rd gear in WG65 applications.

Technical Specifications

Compatibility

This shaft is primarily designed for the ZF WG65 series, but it also fits select models in the WG180 and WG200 families due to shared planetary carrier architecture. It is directly compatible with transmissions using the 4616101119: TRANSMISSION HOUSING casting. Always verify your transmission serial number before ordering, as minor revisions exist between early and late production units.
