ZF 4644.303.250 OUTPUT SHAFT for WG200 | OEM Genuine Part

Overview

The ZF 4644.303.250 OUTPUT SHAFT is a critical driveline component engineered specifically for the WG 200 series powershift transmission. This OEM genuine part transmits rotational torque from the planetary gearset to the vehicle’s drive axle, ensuring smooth power delivery under heavy loads. Machined from high-tensile alloy steel, the shaft interfaces directly with the 4460115043: HOUSING and is supported by precision bearings to maintain axial alignment. The SKU 4644.303.250 is a direct replacement for worn or damaged output shafts in ZF’s off-highway and industrial drivetrains.

Symptoms of Failure

• Oil leaks at the output flange seal: A worn shaft surface or damaged splines can compromise the 0734319337: SHAFT SEAL, leading to visible transmission fluid seepage.
• Gear slipping under load: Excessive backlash or fretting on the shaft’s splined section causes intermittent power loss, especially during torque converter lockup.
• Vibration or driveline shudder: Bearing journal wear on the shaft creates radial play, which is amplified through the 4469315012: AXLE DRIVE HOUSING.
• Metallic debris in transmission oil: Spalling on the shaft’s hardened surface introduces ferrous particles into the lubrication circuit, accelerating wear on the 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING.

Technical Specifications

Compatibility

This output shaft is designed for the ZF WG 200 series powershift transmissions. It is also compatible with the WG180 and WG210 models when used with the correct 0730161317: WASHER and 0730161340: WASHER shim sets. The shaft fits all WG200 variants (WG200, WG200-2, WG200-3) used in wheel loaders, forklifts, and industrial tractors. Always verify the bearing bore dimensions against the 4469315012: AXLE DRIVE HOUSING before installation.
