ZF 4661.276.001 COUPLING for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.276.001 COUPLING is a critical driveline component engineered specifically for the WG 90 and WG 94 series transmissions. This OEM genuine part serves as the primary mechanical link between the engine output and the transmission input shaft, ensuring precise torque transfer and dampening torsional vibrations. Located within the bell housing assembly, the coupling interfaces directly with the 4661101013: TRANSMISSION HOUSING to maintain axial alignment and rotational stability. The SKU 4661.276.001 is manufactured to ZF’s exacting tolerances, guaranteeing seamless integration with the WG 94 series drivetrain architecture.

Symptoms of Failure

When the ZF 4661.276.001 coupling begins to degrade, operators may notice several distinct failure indicators. Transmission gear slipping under load is a common symptom, often accompanied by a metallic grinding noise during acceleration. Oil leaks near the bell housing can occur as the coupling’s sealing surface wears, allowing transmission fluid to escape past the 4661301022: HOUSING. Excessive driveline vibration at highway speeds indicates the coupling has lost its dampening capacity, while hard shifting between forward gears suggests the coupling’s splines have worn unevenly. These issues progressively worsen if the 0631306174: CYLINDRICAL PIN securing the coupling becomes loose.

Technical Specifications

Compatibility

This coupling is primarily designed for the ZF WG 94 series transmissions, including models WG 94, WG 94-2, and WG 94-3. It is also compatible with the WG 90 series (WG 90, WG 90-1) and select WG 180 variants when used with the appropriate 0769123894: TYPE PLATE for identification. The part fits all WG 200 series units that share the same bell housing pattern as the WG 94. Always verify the coupling’s spline count and pilot bore diameter against your transmission’s input shaft specifications before installation.
