Overview
The ZF 4657.298.102 HOUSING REAR SECTION is a critical structural component designed for the WG190, WG210, and WG230 series transmissions. This OEM genuine part encloses the rear planetary gearset and output shaft assembly, providing precise alignment and sealing for the transmission’s final drive section. The SKU 4657.298.102 serves as the primary rear casing that integrates with the 4657101082: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT to form a complete, sealed transmission assembly. Manufactured from high-strength cast iron, this housing section withstands extreme torsional loads and thermal expansion during heavy-duty industrial operations.
Symptoms of Failure
- Rear main seal oil leakage: When the housing rear section warps or develops micro-cracks, transmission fluid seeps past the output shaft seal, leaving visible puddles under the vehicle or machinery.
- Gear slipping under load: A distorted housing bore misaligns the planetary gearset, causing intermittent power loss or harsh engagement during acceleration or uphill operation.
- Abnormal rear-end noise: Worn bearing seats within the housing produce a rhythmic whining or grinding sound from the transmission’s rear section, especially at highway speeds.
- Vibration at the driveshaft flange: Cracks in the housing mounting flange allow the output shaft to wobble, transmitting noticeable vibration through the driveline during deceleration.

Compatibility
This housing rear section is engineered for the ZF WG190, WG210, and WG230 series transmissions. It also fits select variants of the WG180 and WG200 models when used with the appropriate 0631306816: CYLINDRICAL PIN for alignment. The part is not backward-compatible with older WG120 or WG150 series without significant modification. For proper installation, always pair this housing with the 4657201170: HOUSING REAR PART to ensure correct oil channel routing.

Frequently Asked Questions
Q: Can the ZF 4657.298.102 housing be repaired if it has a hairline crack?
A: While minor cracks can sometimes be welded by a certified specialist, ZF recommends replacement with this OEM genuine part to maintain structural integrity and avoid future oil leaks. The housing’s cast iron composition makes welding risky without proper preheating and stress relief.
Q: What torque specification should I use for the bolts securing this housing?
A: For the M12 bolts connecting this rear section to the main transmission housing, apply 80 Nm (59 ft-lbs) in a crosswise pattern, followed by a 90-degree angle turn. Always use new 0636100801: CAP SCREW fasteners to prevent thread galling.
Q: Does this part include the output shaft seal or bearing?
A: No, the 4657.298.102 is supplied as a bare housing casting. You must install the seal, bearing, and 0631306816: CYLINDRICAL PIN separately. We recommend replacing the 4656301148: FIXING PLATE simultaneously to maintain proper bearing preload.
