Overview
The ZF 4642.101.472 TRANSMISSION HOUSING is a critical structural component designed specifically for the WG150 series. As the main casing, it encloses and protects the gear train, clutch packs, and hydraulic valve body, ensuring precise alignment of internal shafts under high torque loads. This OEM genuine part, identified by SKU 4642.101.472, serves as the rigid backbone that absorbs torsional stress and maintains oil circulation pathways. It is often replaced in conjunction with the 4642101109 TRANSMISSION HOUSING or the 4642301205 TRANSMISSION HOUSING during a full rebuild of the WG150 assembly.
Symptoms of Failure
- External oil seepage at mating surfaces: Cracks or porosity in the housing allow transmission fluid to weep from bolt holes or flange edges, often mistaken for a simple gasket leak.
- Gear engagement hesitation or slipping: Warpage of the housing bore distorts clutch pack clearances, leading to delayed shifts or torque loss under load.
- Unusual metallic grinding noises: Bearing bore wear causes shaft misalignment, resulting in gear tooth contact wear and audible chatter during operation.
- Contaminated fluid from debris ingress: Fractures near the bell housing allow road grit and moisture to enter, accelerating internal wear.

Compatibility
This housing is engineered for the ZF WG150 transmission series. It is also compatible with the WG180 and WG200 models when used with the appropriate adapter kit, as the bell housing bolt pattern and main bearing bore dimensions are shared across these medium-duty off-highway transmissions. Always verify the casting number against your unit. For complete assembly, pair this housing with the 0730365125 TYPE PLATE for identification and the 0631311009 GROOVED STUD for secure mounting.
