Overview
The ZF 4657.201.013 HOUSING REAR PART is a critical structural component engineered for the WG190 and WG210 series transmissions. This OEM genuine part forms the aft enclosure of the transmission casing, providing essential support for the output shaft assembly and sealing the internal hydraulic circuits. The SKU 4657.201.013 ensures a precise fit within the modular housing architecture, working in concert with the 4657101039: TRANSMISSION HOUSING to maintain structural rigidity under heavy torque loads. By anchoring the rear bearing cluster, this housing rear part prevents axial displacement and maintains proper gear alignment throughout the drivetrain.
Symptoms of Failure
- Rear seal oil leaks: When the housing rear part warps or develops micro-fractures, transmission fluid seeps past the output shaft seal, leaving visible puddles under the vehicle bell housing area.
- Output shaft wobble: A worn or cracked rear housing allows excessive radial play in the output shaft, causing driveline vibration during acceleration between 30-50 mph.
- Gear engagement hesitation: Distortion of the housing rear part disrupts hydraulic pressure to the rear clutch pack, resulting in delayed or harsh shifts when moving from neutral to drive.
- Metallic debris in fluid: Internal fretting between the housing and the 0631306792: CYLINDRICAL PIN can generate fine metal particles that contaminate the transmission oil.

Compatibility
This housing rear part is specifically designed for ZF WG190 and WG210 series transmissions, commonly found in medium-duty commercial vehicles and off-highway equipment. It is also compatible with the closely related WG180 and WG200 models when used with the appropriate 4656301023: GASKET. The part interfaces directly with the 4657201028: HOUS.FRONT SECT to form the complete transmission casing assembly. For proper installation, use the 0636100801: CAP SCREW set to achieve the specified torque values.

Frequently Asked Questions
Q: Can I install the 4657.201.013 housing rear part without replacing the gasket?
No. The sealing surface is critical for preventing fluid migration. Always replace the 4656301023: GASKET simultaneously to ensure a leak-free joint between the rear housing and the main casing.
Q: How do I verify if my WG210 transmission needs this specific rear housing?
Inspect the casting number on the existing part. If it reads 4657.201.013 and you observe oil weeping from the rear seal area or output shaft play exceeding 0.5 mm, replacement is recommended. Cross-reference with the 4657201028: HOUS.FRONT SECT to confirm model compatibility.
Q: What torque specification should I use for the cap screws?
Use 85 Nm (62.7 lb-ft) for the 0636100801: CAP SCREW fasteners. Apply thread locker to the bolts and tighten in a star pattern to prevent housing distortion.
