ZF 4646.302.095 CONVERTER BELL for WG250 | OEM Genuine Part

Overview

The ZF 4646.302.095 CONVERTER BELL is a critical structural component designed for the WG250 series automatic transmission. 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 4646.302.095 is engineered to withstand high torsional loads and thermal expansion, directly supporting the converter’s rotational stability. It mounts between the engine flywheel housing and the TRANSMISSION HOUSING, forming a sealed enclosure that protects internal components from debris and contamination.

Symptoms of Failure

• Torque converter oil leaks at the bell housing seam: A worn or cracked 4646.302.095 bell often causes transmission fluid to seep from the joint, leaving visible drips under the vehicle.
• Vibration or shudder during gear engagement: Misalignment due to a distorted converter bell leads to irregular torque transfer, especially under load.
• Metallic grinding noises near the bell area: Internal contact between the converter and housing occurs when the bell’s mounting flange fatigues, producing audible wear sounds.
• Difficulty in transmission removal or reinstallation: A warped bell housing can bind against the HEXAGON SCREW fasteners, complicating service procedures.

Technical Specifications

Compatibility

This converter bell is specifically engineered for the ZF WG250 series, but it also fits select models in the WG180, WG200, and WG300 families due to shared bell-housing dimensions. It is a direct replacement for transmissions used in municipal buses, construction loaders, and medium-duty trucks. Always verify the bolt pattern against your existing HOUSING and COVER assembly to ensure proper sealing.
