Overview
The ZF 4657.201.169 HOUSING REAR PART is a critical structural component engineered for the WG190 and WG210 series transmissions. This OEM genuine part encloses the rear planetary gearset and output shaft assembly, providing precise alignment and sealing within the transmission housing. As the rearmost section of the main casing, it directly interfaces with the 4657101079: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT to form a complete, oil-tight assembly. The SKU 4657.201.169 is machined from high-strength cast iron to withstand the torsional loads and thermal expansion inherent in heavy-duty industrial applications.
Symptoms of Failure
- Rear seal oil leakage: A worn or cracked housing rear part often causes transmission fluid to weep from the output flange area, leaving puddles under the vehicle or machine.
- Output shaft misalignment: When the housing rear section fatigues, the output bearing bore can distort, leading to vibration and premature bearing wear during operation.
- Gear noise from the rear section: If the housing rear part develops hairline fractures, you may hear a distinct whining or grinding noise from the back of the transmission under load.
- Intermittent gear slipping: A compromised housing can allow the rear planetary carrier to shift slightly, causing momentary loss of torque transfer during acceleration.

Frequently Asked Questions
Q: Can I install the 4657.201.169 housing rear part without removing the entire transmission?
A: In most applications, you can replace this part by supporting the transmission and unbolting the rear cover assembly. However, access to the output flange and rear seal requires partial disconnection of the driveshaft.
Q: Is the 4657.201.169 the same as the 4657298104 housing rear section?
A: No. The 4657.201.169 is a complete housing rear part that includes the bearing bore and seal surface, while the 4657298104 is a separate rear section that bolts onto the main housing. They are not interchangeable.
Q: What torque specification should I use for the cap screws securing this part?
A: Use 80 Nm (59 ft-lbs) for the M12 bolts, applied in a crosswise pattern. Always refer to the ZF service manual for your specific transmission model.
