ZF 4166.030.141 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4166.030.141 CONVERTER Torque Converter Assembly is a critical hydraulic coupling unit positioned between the engine flywheel and the transmission input shaft within the WG 150 Series gearbox. This complete unit transfers and multiplies engine torque through fluid dynamics, enabling smooth power delivery and load management in heavy-duty industrial applications. The SKU 4166.030.141 is engineered as a direct replacement assembly, ensuring precise fitment and OEM-level performance for ZF driveline systems.

Symptoms of Failure

• Torque converter shudder or vibration during acceleration: Worn internal clutch plates or damaged stator bearings cause irregular fluid flow, leading to noticeable shaking when shifting from a stop.
• Delayed engagement or gear slipping under load: A failing 4166.030.141 unit cannot maintain proper hydraulic pressure, resulting in sluggish takeoff or unexpected gear disengagement during operation.
• Overheating transmission fluid with burnt odor: Internal seal degradation or impeller wear generates excessive friction, raising fluid temperatures and producing a distinct burnt smell from the dipstick or vent.
• Visible fluid leaks near the bell housing area: Cracked converter housing or failed pump drive seals allow transmission oil to escape, often pooling beneath the vehicle or equipment.

Technical Specifications

Compatibility

This torque converter assembly is primarily designed for the ZF WG 150 Series transmission family. It is also compatible with select models in the WG 180 and WG 200 series when used with the appropriate TRANSMISSION HOUSING (4642101109) or TRANSMISSION HOUSING (4642301205). For correct identification, always verify the TYPE PLATE (0730365125) on your existing unit. Secure mounting requires the GROOVED STUD (0631311009) to ensure proper alignment with the flywheel assembly.
