Overview
The ZF 4642.152.496 COUPLING for WG 150 is a critical OEM genuine component engineered to transmit rotational force between the engine output and the transmission input shaft within the WG 150 series. This precision-machined coupling absorbs torsional vibrations and ensures smooth power delivery, directly influencing drivetrain efficiency and component longevity. The SKU 4642.152.496 is specifically designed to interface with the 4642101047 TRANSMISSION HOUSING and the 4642301207 TRANSMISSION HOUSING, forming a sealed assembly that prevents contamination. As an OEM genuine part, it guarantees exact fitment and material integrity for demanding industrial applications.
Symptoms of Failure
- Torque fluctuation under load: A worn 4642.152.496 coupling causes noticeable power surges or hesitation during acceleration, often misdiagnosed as gear slipping.
- Metallic rattling from bell housing: Loose or fatigued coupling teeth produce a distinct clattering noise at idle or low RPM, indicating imminent failure.
- Transmission fluid contamination: Cracks in the coupling hub allow debris to enter the oil circuit, leading to premature wear of the 4642301168 SCREEN SHEET and 4642301169 SCREEN SHEET filters.
- Vibration at specific RPM ranges: Imbalance from a degraded coupling creates resonant vibrations that can loosen the 0636100621 HEXAGON SCREW fasteners.

Compatibility
This coupling is primarily designed for the ZF WG 150 series, but it also fits select models in the WG 180 and WG 200 families when paired with the correct 0730365067 TYPE PLATE for identification. It is compatible with transmissions using the 0631311009 GROOVED STUD mounting pattern. Always verify fitment by cross-referencing the housing part numbers: 4642101047 and 4642301207. The coupling also works with the 4642301186 SCREEN SHEET and 4644106300 SHIFT SYSTEM for complete driveline restoration.
