Overview
The ZF 4657.298.101 HOUSING REAR SECTION is a structural OEM genuine component engineered for the WG190 transmission series. This precision-machined housing encloses the rear planetary gearset and output shaft assembly, providing critical alignment and load-bearing support within the drivetrain. As a rear section, it seals the transmission’s internal oil system and anchors the output flange. The SKU 4657.298.101 is a direct replacement part designed to restore factory tolerances and prevent premature wear in heavy-duty commercial vehicles. This housing works in concert with the 4657101078: TRANSMISSION HOUSING to form the complete main casing assembly.
Symptoms of Failure
- Rear output seal oil leakage: A worn or cracked housing rear section often causes transmission fluid to weep from the output shaft area, leaving visible puddles under the vehicle.
- Vibration during gear engagement: Degraded bearing bores in the housing lead to shaft misalignment, producing low-frequency shuddering when shifting into drive or reverse.
- Metallic debris in transmission fluid: Internal fractures or fretting of the housing rear section can shed aluminum or steel particles, contaminating the oil and clogging filters.
- Intermittent gear slippage under load: Loss of structural rigidity in the rear housing allows planetary gears to drift out of mesh, causing momentary power loss during uphill climbs.

Compatibility
This OEM housing rear section is designed for ZF WG-series transmissions, specifically the WG190 model. It also fits the WG180, WG200, WG210, and WG230 series when used with the appropriate adapter components. The part is a direct match for BP 210 and BP 230 series transmissions that share the same rear housing architecture. For proper installation, pair this housing with the 4657201166: HOUS.FRONT SECT and the 4657201168: HOUSING REAR PART to complete the casing assembly. Secure the housing using the 0631306816: CYLINDRICAL PIN for precise alignment during reassembly.

Frequently Asked Questions
Q: Can the 4657.298.101 housing be used on a WG210 transmission?
A: Yes, this housing rear section is compatible with WG210 models, provided the output flange and bearing carrier match the WG210’s 210 mm bolt pattern. Always verify the seal bore diameter against your existing unit.
Q: What torque specification should I use for the housing bolts?
A: For the M12 cap screws (part 0636100801), apply 80 Nm (59 ft-lbs) in a crosswise pattern. The cylindrical pin 0631306816 must be fully seated before torquing to prevent misalignment.
Q: Does this part include the rear oil seal?
A: No, the housing rear section is supplied as a bare casting. You will need to install a new output shaft seal separately. We recommend replacing the 4681301040: OIL FEED.HOUSG. tube at the same time to prevent future leaks.
