ZF 4651.152.012 COUPLING for WG 100/WG 110 | OEM Genuine Part

Overview

The ZF 4651.152.012 COUPLING is a critical driveline component engineered specifically for the WG 100 and WG 110 transmission series. This OEM genuine part functions as the primary torque-transfer interface between the engine output and the transmission input shaft, ensuring smooth power delivery under heavy industrial loads. The SKU 4651.152.012 sits directly within the bell housing assembly, where it absorbs torsional vibrations and maintains precise alignment during high-stress operations. As a factory-spec coupling, it guarantees exact fitment and material integrity for demanding B2B applications.

Symptoms of Failure

• Torque converter shudder during acceleration: A worn 4651.152.012 coupling causes noticeable vibration or jerking when shifting from neutral to drive, especially under load.
• Transmission fluid contamination with metallic debris: Degraded coupling splines shed metal particles into the oil, visible during routine filter inspections.
• Intermittent loss of power transfer: Operators report hesitation or “slipping” sensations when the coupling fails to maintain positive engagement between engine and transmission.
• Abnormal noise from the bell housing area: A clicking or grinding sound during gear changes indicates coupling wear or spline damage.

Technical Specifications

Compatibility

This coupling is designed for the ZF WG 100 and WG 110 transmission series. It is also compatible with select models in the WG 180 and WG 200 families where the bell housing configuration matches. Always verify spline count and pilot bore dimensions before installation. The part interfaces directly with the 4651101007: TRANSMISSION HOUSING and the 4651301029: HOUSING to form the sealed driveline assembly. Proper sealing is ensured by the 0634303928: O-RING, while the 4651301024: HOUSING provides the structural mounting point for the coupling.
