ZF 4644.311.032 OUTPUT SHAFT for WG200 | OEM Genuine Part

Overview

The ZF 4644.311.032 OUTPUT SHAFT is a critical torque-transferring component engineered for the WG 200 series of powershift transmissions. This OEM genuine part transmits rotational force from the planetary gear set to the driveline flange, ensuring smooth power delivery in heavy-duty industrial vehicles. Precision-machined from high-tensile alloy steel, the 4644.311.032 shaft interfaces directly with the TRANSMISSION HOUSING (4644101216) and the TRANSMISSION HOUSING (4644301223) to maintain concentric alignment under extreme loads. Each shaft is factory-balanced to OEM specifications, reducing vibration and extending bearing life. The SKU 4644.311.032 is laser-etched for traceability and includes the original TYPE PLATE (0730365067) for verification during installation.

Symptoms of Failure

• Transmission output flange oil leaks – Worn splines or seal surfaces on the 4644.311.032 shaft allow transmission fluid to weep past the output seal, leaving puddles under the vehicle.
• Driveline vibration at highway speeds – A fatigued output shaft develops microscopic cracks or runout, causing rhythmic shaking that worsens under load.
• Gear engagement delay or clunking – Stripped or worn splines on the shaft prevent positive lock-up with the output hub, resulting in a noticeable lag when shifting from neutral to drive.
• Metal debris in transmission pan – Spalling or galling on the shaft surface sheds ferrous particles into the oil, often detected during routine filter inspections.

Technical Specifications

Compatibility

This output shaft is primarily designed for the ZF WG 200 series, including the WG200, WG200C, and WG200E variants used in wheel loaders, forklifts, and airport ground support equipment. It also fits select WG180 models that share the same output housing geometry. Always verify the GROOVED STUD (0631311009) alignment before installation, as incorrect stud orientation can damage the shaft splines. For earlier WG160 transmissions, consult the parts interchange manual to confirm compatibility.
