ZF 4168.034.146 CONVERTER Torque Converter Assembly | Complete Unit

Overview

The ZF 4168.034.146 CONVERTER Torque Converter Assembly is a critical hydraulic coupling unit designed for the WG 210 Series transmission family. This complete assembly transfers engine torque to the transmission input shaft while multiplying rotational force during low-speed operation. Positioned between the engine flywheel and the transmission housing, the SKU 4168.034.146 integrates a lock-up clutch mechanism to improve fuel efficiency at highway speeds. As a direct replacement unit, it eliminates the need for partial rebuilds, ensuring reliable power delivery in heavy-duty industrial applications.

Symptoms of Failure

• Torque converter shudder or vibration during acceleration, often caused by worn clutch friction material inside the assembly.
• Transmission fluid overheating due to internal stator failure, leading to reduced converter efficiency and potential damage to the TRANSMISSION HOUSING.
• Delayed or harsh gear engagement when shifting from Park to Drive, indicating a failing one-way clutch or impeller damage.
• Visible fluid leaks from the converter hub seal area, often accompanied by low transmission fluid levels and slipping gears.

Technical Specifications

Compatibility

This torque converter assembly is engineered for the ZF WG 210 Series and is also compatible with WG 180, WG 200, and WG 211 transmission models used in construction, agricultural, and material handling equipment. It directly replaces earlier converter variants in these series without modification. For proper installation, ensure the HOUS.FRONT SECT and HOUSING REAR PART are free from wear. Secure the assembly using the CYLINDRICAL PIN for alignment during mounting.
