ZF 4651.152.008 COUPLING for WG 100/WG 110 | OEM Genuine Part

Overview

The ZF 4651.152.008 COUPLING is a critical torque-transfer component engineered specifically for the WG 100 and WG 110 transmission series. This OEM genuine part acts as the mechanical link between the engine output and the transmission input shaft, ensuring smooth power delivery and dampening torsional vibrations. The SKU 4651.152.008 is precision-machined to ZF’s exacting tolerances, making it a direct replacement for worn units in heavy-duty industrial drivelines. It sits within the bell housing assembly, directly interfacing with the 4651101006: TRANSMISSION HOUSING and the 4651301034: HOUSING to maintain concentric alignment under load.

Symptoms of Failure

When the ZF 4651.152.008 COUPLING begins to degrade, operators may notice several distinct failure indicators. Common symptoms include:

• Torque converter shudder or vibration during low-speed engagement, often misdiagnosed as a transmission slipping issue.
• Metallic rattling noises emanating from the bell housing area, particularly when shifting between forward and reverse gears.
• Premature wear on the input shaft seal caused by coupling imbalance, leading to fluid contamination and eventual leakage.
• Intermittent loss of power transfer under heavy load, where the coupling splines strip or the damping element fatigues.

Technical Specifications

Compatibility

This coupling is designed primarily for the ZF WG 100 and ZF WG 110 series transmissions, commonly found in forklifts, telehandlers, and industrial loaders. It is also compatible with the WG 180 and WG 200 models when used in conjunction with the appropriate 0634303928: O-RING and 4651301013: HOUSING adapter. Always verify spline count and pilot bore dimensions before installation, as variations exist between early and late production units.
