Overview
The ZF 4657.354.070 HOUSING is a critical structural component designed for the WG 190 and WG 210 transmission series. This OEM genuine part serves as the primary enclosure that houses the planetary gear sets, valve body, and hydraulic circuits within the transmission assembly. Positioned centrally in the drivetrain, this housing ensures precise alignment of internal rotating elements and maintains the integrity of the oil sump. The SKU 4657.354.070 is manufactured to ZF’s exacting tolerances, providing a leak-proof interface for the 4657101033: TRANSMISSION HOUSING and the 4657201027: HOUS.FRONT SECT to which it bolts directly.
Symptoms of Failure
- External oil seepage from housing mating surfaces: When the 4657.354.070 housing develops cracks or warpage, transmission fluid leaks appear at the joint between this housing and the 4657201012: HOUSING REAR PART, often mistaken for a simple gasket failure.
- Abnormal gear engagement noise or harsh shifting: A worn housing can allow the internal planetary carriers to shift out of alignment, causing metallic grinding sounds during gear changes in WG 210 transmissions.
- Loss of hydraulic pressure leading to clutch slip: Cracks in the housing wall disrupt oil galleries, resulting in low line pressure and delayed engagement under load.
- Contamination from metal debris in the oil pan: A fractured housing sheds aluminum particles into the fluid, which can clog the 0631306792: CYLINDRICAL PIN bores and accelerate wear on other components.

Compatibility
This housing is engineered for the ZF WG 190 and WG 210 series powershift transmissions commonly found in heavy-duty construction equipment and agricultural machinery. It is directly compatible with the following transmission models: WG 180, WG 190, WG 200, and WG 210. The 4657.354.070 housing interfaces specifically with the 4657101033: TRANSMISSION HOUSING and the 4657201027: HOUS.FRONT SECT to form the complete main casing assembly. It also accepts the 4657201012: HOUSING REAR PART on the output side and the 0631306792: CYLINDRICAL PIN for precise dowel alignment during assembly.
