Overview
The ZF 4644.323.024 OUTPUT SHAFT is a critical driveline component engineered specifically for the ZF WG200 series powershift transmission. This OEM genuine part transmits rotational torque from the planetary gearset to the vehicle’s final drive, ensuring smooth power delivery under heavy-duty operating conditions. Machined from high-tensile alloy steel and precision-ground to exacting tolerances, the SKU 4644.323.024 serves as the primary interface between the transmission output and the driveshaft, directly influencing shift quality and load-holding capacity. When installed, it mates with the 4460165051 CONSOLE and the 4460368311 CONSOLE to form a rigid support structure within the transmission housing.
Symptoms of Failure
- Oil leaks at the output seal area – Worn splines or a scored shaft surface can damage the lip seal, causing transmission fluid to weep or stream from the rear housing. This often appears as a puddle under the bell housing after parking.
- Gear slipping under load – A fatigued output shaft may allow the clutch pack to lose engagement, resulting in intermittent power loss or a “flare” between shifts during uphill hauling.
- Vibration or driveline shudder – Bent or unbalanced shafts produce rhythmic shaking felt through the chassis, especially at highway speeds or when the transmission is under torque.
- Abnormal noise (clunking or grinding) – Worn splines or bearing journals create metal-on-metal contact, audible as a distinct clunk when shifting from neutral to drive or reverse.

Compatibility
This ZF 4644.323.024 OUTPUT SHAFT is primarily designed for the WG200 series transmission, but it also fits select variants of the WG180 and WG250 models where the output flange interface is identical. It is commonly used in off-highway equipment such as wheel loaders, dump trucks, and agricultural tractors. For proper installation, always pair this shaft with the 0636011429 HEXAGON SCREW and the 0730100365 WASHER to secure the output flange assembly. Verify your transmission’s serial number against ZF’s parts catalog before ordering.
