ZF 4616.302.056 INPUT SHAFT for WG65 | OEM Genuine Part

Overview

The ZF 4616.302.056 INPUT SHAFT is a critical drivetrain component engineered specifically for the WG 65 Series transmission. This OEM genuine part transmits rotational force from the engine clutch directly into the planetary gear set, acting as the primary torque receiver within the gearbox assembly. Precision-machined from high-grade alloy steel, the SKU 4616.302.056 ensures minimal backlash and optimal power transfer under heavy-duty industrial loads. When paired with a properly sealed 4616105402: OUTPUT shaft, this input shaft maintains driveline integrity across all gear ranges.

Symptoms of Failure

• Transmission gear slipping under load – Worn splines on the 4616.302.056 cause intermittent engagement, especially during uphill hauls or sudden acceleration.
• Oil leaks at the bell housing – A damaged input shaft seal surface allows transmission fluid to weep past the front seal, leaving puddles under the vehicle.
• Vibration during clutch engagement – Bent or fatigued shafts produce rhythmic shaking that intensifies when the clutch pedal is released.
• Metallic grinding noises from the gearbox – Advanced wear on the shaft bearing journals creates audible contact with the 4616101119: TRANSMISSION HOUSING.

Technical Specifications

Compatibility

This input shaft is factory-specified for the ZF WG 65 Series, but its spline geometry and pilot bearing dimensions also suit the WG180, WG200, and WG250 transmission models. For proper installation, always replace the 4005303005: OUTPUT FLANGE and torque the 0636011038: HEXAGON SCREW to factory specifications. The shaft interfaces directly with the clutch pilot bearing and requires a clean TRANSMISSION HOUSING bore for concentric alignment.
