Overview
The ZF 4168.034.147 CONVERTER Torque Converter Assembly is a complete, ready-to-install unit engineered for the WG 210 Series transmission family. This critical component sits between the engine flywheel and the transmission input shaft, functioning as a fluid coupling that multiplies engine torque while dampening driveline vibrations. The SKU 4168.034.147 replaces worn or failed converters to restore full power transfer efficiency and smooth engagement in heavy-duty industrial applications. When installing this assembly, ensure the 4657101042 TRANSMISSION HOUSING is properly aligned to prevent misalignment issues.
Symptoms of Failure
- Shuddering or vibration during acceleration – A failing torque converter often causes noticeable shuddering when the vehicle moves from a stop, indicating worn internal clutch linings or damaged stator bearings.
- Delayed or harsh gear engagement – If the converter fails to lock up properly, operators experience a lag between shifting and actual gear engagement, sometimes accompanied by a clunking noise.
- Overheating transmission fluid – A slipping converter generates excessive heat, leading to burnt-smelling fluid and potential damage to the 4657201028 HOUS.FRONT SECT and surrounding seals.
- Visible fluid leaks near the bell housing – Worn converter hub seals or cracks in the housing can cause transmission fluid to drip, often mistaken for engine oil leaks.

Compatibility
This torque converter is specifically designed for the ZF WG 210 Series transmissions. It is also compatible with earlier WG 180 and WG 200 models when used with the correct adapter plate. The unit directly replaces OEM converters in ZF 4WG-210, 5WG-210, and 6WG-210 gearboxes found in construction equipment, agricultural tractors, and material handlers. For proper installation, verify that the 4657201013 HOUSING REAR PART is free of cracks and that the 0631306792 CYLINDRICAL PIN is correctly seated to secure alignment.
