ZF 4661.330.003 CONVERTER BELL for WG94 | OEM Genuine Part

Overview

The ZF 4661.330.003 CONVERTER BELL is a critical structural component engineered for the WG 94 Series transmission family. This OEM genuine part serves as the rigid housing that connects the torque converter assembly to the main transmission casing, ensuring precise alignment of the driveline. The SKU 4661.330.003 is specifically designed to absorb torsional loads and maintain concentricity between the engine flywheel and the transmission input shaft. It sits directly between the engine block and the 4661101013: TRANSMISSION HOUSING, forming the forward-most section of the gearbox assembly. Without this bell housing, the converter would lack structural support, leading to catastrophic misalignment under heavy-duty industrial operation.

Symptoms of Failure

When the ZF 4661.330.003 converter bell begins to wear, operators typically encounter these specific failure modes:

• Torque converter oil leaks at the bell housing seam – Cracks or warping in the bell allow transmission fluid to escape, often visible as drips near the engine-transmission junction.
• Vibration during gear engagement – A worn bell loses its ability to maintain converter alignment, causing rhythmic shaking when shifting from neutral to drive or reverse.
• Metallic grinding noises from the bell area – Internal contact between the converter and the bell interior occurs when the housing distorts, producing a distinct scraping sound under load.
• Premature failure of the input shaft seal – Misalignment from a degraded bell accelerates seal wear, leading to recurrent fluid loss and eventual gear slipping.

Technical Specifications

Compatibility

This converter bell is specifically engineered for the ZF WG 94 Series transmission family. It is directly compatible with the following models: WG94, WG180, WG200, WG210, and WG240 transmissions. The part also integrates seamlessly with the 4661301022: HOUSING and requires the 0631306174: CYLINDRICAL PIN for precise dowel alignment during installation. For identification purposes, the 0769123894: TYPE PLATE should be affixed to this bell housing after assembly to ensure traceability.
