Signs You Need to Replace the Bell Housing
The Converter Bell Housing is the structural backbone connecting your engine to the ZF 4WG210 Transmission. In heavy-duty applications like wheel loaders (e.g., John Deere 644H, Doosan Mega 300), this component endures immense stress.
You should inspect and consider replacing part 4657.330.023 if you notice:
- Hairline Cracks: Visible near the engine mounting flange or engine mounts due to chassis flexing.
- Input Shaft Vibration: Caused by a warped housing losing concentricity with the flywheel.
- Oil Leaks: Persistent transmission fluid leaks at the converter mating surface that gasket replacement won’t fix.
- Pump Failure: Repeated failure of the charging pump (indicating misalignment).
The Genuine ZF Solution: 4657.330.023
Don’t risk welding a cracked housing. A repaired casting rarely holds alignment, leading to catastrophic input shaft or torque converter failure.

Installation Tips
When installing the new 4657.330.023 housing, we recommend the following best practices to ensure longevity:
Check the Flywheel: Ensure the engine flywheel runout is within spec before bolting on the new housing.
Replace Seals: Always install a new Input Shaft Seal and O-rings. (We can supply the matching Seal Kit).
Torque Specs: Follow the ZF workshop manual for proper bolt torque sequences to prevent warping the new casting.
