ZF 4651.151.009 COUPLING for WG 100/WG 110 | OEM Genuine Part

Overview

The ZF 4651.151.009 COUPLING is a critical torque-transfer component engineered specifically for the WG 100 and WG 110 transmission series. This OEM genuine part sits between the engine flywheel and the transmission input shaft, acting as a flexible mechanical link that absorbs torsional vibrations and ensures smooth power delivery. The SKU 4651.151.009 is precision-machined to ZF’s exacting tolerances, guaranteeing a direct fit without modification. When installed alongside the 4651101007: TRANSMISSION HOUSING, this coupling maintains proper alignment and load distribution across the driveline.

Symptoms of Failure

When the ZF 4651.151.009 coupling begins to degrade, operators often notice excessive driveline vibration during acceleration—a clear sign the damping material has fatigued. Another common failure symptom is intermittent gear slipping under heavy load, as the coupling loses its ability to maintain consistent torque transfer. You may also detect metallic rattling noises from the bell housing area, indicating worn splines or cracked coupling segments. Finally, visible rubber debris near the transmission bell housing suggests the coupling is disintegrating internally, requiring immediate replacement to prevent damage to the 4651301029: HOUSING.

Technical Specifications

Compatibility

This coupling is primarily designed for the ZF WG 100 and ZF WG 110 transmission models, commonly found in medium-duty trucks, buses, and industrial machinery. It is also compatible with the WG 180 and WG 200 series when used with the correct adapter hardware. For proper sealing during installation, always pair this part with a new 0634303928: O-RING to prevent fluid leaks at the housing interface. The coupling works in conjunction with the 4651301024: HOUSING to create a sealed, lubricated chamber for the internal components.
