Overview
The ZF 4657.201.162 HOUSING REAR PART is a precision-machined structural component designed for the WG190, WG210, and WG230 series transmissions. This OEM genuine part forms the aft enclosure of the transmission casing, directly supporting the output shaft assembly and containing the rear bearing cluster. The SKU 4657.201.162 interfaces with the main TRANSMISSION HOUSING and the HOUS.FRONT SECT to create a sealed, rigid assembly that withstands high torque loads and thermal expansion. As a genuine ZF component, it ensures exact bolt-hole alignment and maintains critical tolerances for oil circulation channels.
Symptoms of Failure
- Rear seal oil leakage: A worn or cracked housing rear part allows transmission fluid to weep from the output shaft area, often visible as drips under the vehicle after parking.
- Output shaft vibration or noise: When the housing rear part loses structural integrity, bearing support degrades, causing a low-frequency rumble or whine during acceleration in higher gears.
- Gear engagement delay or slipping: Distortion in the rear housing can misalign the clutch pack and planetary gear set, leading to delayed shifts or intermittent slipping under load.
- Contaminated fluid from debris ingress: Cracks or porous casting in the housing rear part allow dirt and moisture to enter the transmission, accelerating wear on internal components.

Compatibility
This housing rear part is engineered for ZF WG-series transmissions with modular rear sections. It is directly compatible with the WG190, WG210, and WG230 models. The part also fits select variants of the WG180 and WG200 series when used with the appropriate HOUSING REAR SECTION adapter kit. Always verify the casting number on your existing housing before installation. The CYLINDRICAL PIN (0631306816) is required for precise alignment during assembly.

Frequently Asked Questions
Q: Can I install the 4657.201.162 housing rear part without removing the transmission from the vehicle?
A: In most applications, the rear housing can be replaced with the transmission in place, provided there is sufficient clearance to access the rear bolt pattern. However, we recommend draining the fluid and supporting the output shaft before unbolting the housing.
Q: What is the torque specification for the cap screws securing this housing?
A: The M10 cap screws (part 0636100801) should be tightened to 45 Nm (33 ft-lb) in a crosswise pattern. Always use new fixing plates (4656301148) to prevent loosening.
Q: Will this part work with a WG230 transmission that has a different bell housing?
A: Yes, the 4657.201.162 is designed for the rear section only and is independent of the bell housing variant. Ensure your transmission serial number falls within the WG190/WG210/WG230 range for guaranteed compatibility.
