ZF 4661.171.001 COUPLING for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.171.001 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 transmission output shaft and the downstream drive components, ensuring precise torque transfer and rotational alignment. Positioned within the rear housing assembly, the coupling absorbs torsional vibrations and maintains concentricity under heavy loads. The SKU 4661.171.001 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in demanding industrial applications.

Symptoms of Failure

• Driveline chatter or clunking during gear engagement: A worn coupling allows excessive play, producing audible metallic noises when shifting or under load.
• Vibration at specific RPM ranges: Degraded elastomeric elements or spline wear cause harmonic imbalances, felt as seat or floorboard vibration.
• Oil seepage near the output flange: Cracks or deformation in the coupling body can compromise the seal interface, leading to gradual fluid loss.
• Erratic power delivery or hesitation: Slippage between the coupling and mating shaft results in intermittent torque transmission, especially during acceleration.

Technical Specifications

Compatibility

This coupling is designed for use in ZF WG 90 and WG 94 series transmissions. It is also compatible with the following models: WG 180, WG 200, WG 211, and WG 250. The part integrates directly with the 4661101001: TRANSMISSION HOUSING and the 4661301007: HOUSING. During installation, ensure the 0631306174: CYLINDRICAL PIN is correctly aligned, and verify that the 4661301093: TUBE is free of obstructions to prevent premature wear.
