ZF 4166.041.023 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4166.041.023 CONVERTER Torque Converter Assembly is a critical hydraulic component that transfers and multiplies engine torque to the transmission input shaft. This complete unit sits between the engine flywheel and the gearbox, using fluid coupling to smooth power delivery and provide torque multiplication during launch. The SKU 4166.041.023 is a direct replacement for the WG 65 Series, ensuring precise fitment and OEM-level performance. When paired with a robust 4616105415: OUTPUT, this converter assembly maintains consistent hydraulic pressure for reliable shifting under heavy loads.

Symptoms of Failure

• Shudder or vibration during acceleration: Worn internal clutches or damaged stator vanes cause irregular torque transfer, especially at low speeds.
• Transmission overheating: A failing converter lock-up clutch generates excessive heat, leading to fluid breakdown and potential damage to the 4616101094: TRANSMISSION HOUSING.
• Delayed or harsh engagement: Reduced hydraulic efficiency from a worn impeller or turbine causes sluggish gear engagement and slipping.
• Fluid contamination or leaks: Internal seal failure allows transmission fluid to mix with engine oil or leak externally, often visible near the bell housing.

Technical Specifications

Compatibility

This torque converter assembly is engineered for ZF WG 65 Series transmissions, commonly found in WG180, WG200, and WG250 models used in heavy-duty trucks, construction equipment, and agricultural machinery. It directly replaces the factory unit and integrates with the 4616303144: OUTPUT FLANGE for proper driveline connection. Always verify your transmission model and serial number before installation to ensure compatibility with your specific housing and output shaft configuration.
