Overview
The ZF 4651.153.006 COUPLING is a precision-engineered component designed for the WG 100 and WG 110 transmission series. This OEM genuine part functions as a critical torque transfer interface within the drivetrain assembly, connecting the engine output to the transmission input shaft. Positioned directly behind the flywheel housing, the coupling absorbs torsional vibrations and ensures smooth power delivery during gear shifts. The SKU 4651.153.006 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in heavy-duty industrial applications.
Symptoms of Failure
When the ZF 4651.153.006 coupling begins to wear, operators may notice several distinct failure indicators. Transmission shudder during acceleration is a common symptom, often caused by degraded elastomeric elements within the coupling. Abnormal gear engagement noise—specifically a clunking or thumping sound when shifting from neutral to drive—signals coupling fatigue. Visible oil seepage around the bell housing can occur if the coupling’s sealing surfaces become compromised. Additionally, reduced fuel efficiency and increased operating temperatures often accompany a failing coupling, as torque transfer becomes less efficient.

Compatibility
This coupling is specifically engineered for the ZF WG 100 and ZF WG 110 transmission series. It is also compatible with the WG 180 and WG 200 models when used in conjunction with the appropriate 4651101005: TRANSMISSION HOUSING. For proper installation, ensure the 4651301010: HOUSING is free from wear, and replace the 0634303928: O-RING during reassembly to prevent leaks. The coupling also interfaces with the 4651301017: HOUSING on later production runs of the WG 100 series.
