ZF 4642.102.087 INPUT for WG150 | OEM Genuine Part

Overview

The ZF 4642.102.087 INPUT for WG150 is a critical OEM genuine component engineered to transfer rotational force from the torque converter directly into the planetary gear sets of the ZF WG150 transmission. Positioned at the front of the main gearcase, this input shaft (SKU: 4642.102.087) interfaces precisely with the TRANSMISSION HOUSING and the TRANSMISSION HOUSING to ensure concentric alignment and smooth power flow. As a genuine ZF part, it guarantees factory-specified tolerances and material integrity, reducing the risk of premature wear in heavy-duty industrial applications.

Symptoms of Failure

• Oil leaks near the bell housing: Worn splines or a damaged input shaft seal can allow transmission fluid to escape, often visible as drips around the front of the unit.
• Gear slipping under load: When the input shaft loses its precise fit with the torque converter hub, the transmission may hesitate or slip during acceleration, especially in higher gears.
• Unusual vibration or noise: A failing input shaft can cause a rhythmic clunking or whining sound that increases with engine RPM, indicating bearing or spline wear.
• Hard shifting or delayed engagement: Misalignment from a worn input shaft can prevent the shift system from engaging correctly, leading to rough or delayed gear changes.

Technical Specifications

Compatibility

This input shaft is primarily designed for the ZF WG150 series transmission. It is also compatible with the ZF WG180 and ZF WG200 models when used with the appropriate TYPE PLATE for identification. Additionally, it can be installed in certain ZF WG120 variants where the input spline configuration matches. Always verify the GROOVED STUD alignment and housing bore dimensions before installation.
