Overview
The ZF 4642.305.011 HOUSING is a structural core component engineered for the WG 150, WG 180, and WG 200 series transmissions. This OEM genuine part encloses the clutch pack and planetary gear set, providing the rigid framework required to withstand high torque loads in heavy-duty industrial applications. The SKU 4642.305.011 is precision-machined to maintain exact bearing alignment and fluid channel integrity. When installed alongside the TRANSMISSION HOUSING (4642101109) and the TRANSMISSION HOUSING (4642301205), it forms the primary structural backbone of the gearbox assembly.
Symptoms of Failure
- External oil seepage at the housing seam: Cracks or porosity in the 4642.305.011 housing often cause persistent transmission fluid leaks, especially under load. Search queries like “ZF WG150 housing oil leak fix” target this symptom.
- Abnormal gear engagement noise: A worn housing can distort under stress, leading to misaligned shafts and a distinct grinding or whining sound during shifts. This is frequently searched as “WG200 transmission housing noise diagnosis”.
- Intermittent gear slipping under heavy load: Loss of structural rigidity in the housing allows clutch packs to shift out of tolerance, causing the transmission to slip when moving heavy equipment. Technicians often search “ZF WG180 slipping housing replacement”.
- Contaminated transmission fluid from metal debris: Internal wear of the housing surface can shed aluminum or iron particles into the oil, which is a common indicator of housing fatigue in WG series units.

Compatibility
This housing is specifically designed for the ZF WG 150 series and is fully compatible with the WG 180 and WG 200 series transmissions. It fits all standard configurations of these models, including those with integrated retarder systems. The 4642.305.011 interfaces directly with the TYPE PLATE (0730365125) for identification and is secured using the GROOVED STUD (0631311009). It is not backward-compatible with older ZF 4HP or 5HP series without significant modification.
