Overview
The ZF 2095.301.025 TRANSMISSION HOUSING is the primary structural core of the ZF powershift transmission assembly. This OEM genuine part encloses and protects the gear train, clutch packs, and hydraulic circuits, ensuring precise alignment of rotating components under heavy loads. As the central casing, it supports the differential and bearing assemblies while maintaining oil pressure integrity. The SKU 2095.301.025 is machined from high-strength cast iron to withstand torsional stress in construction machinery applications. When replacing this housing, technicians often inspect the 5838109007: DIFFERENTIAL and 0750117075: TAPER ROLLER BEARING for wear, as these components seat directly within the housing bores.
Symptoms of Failure
- Oil seepage at mating surfaces – Cracks or warping in the housing cause transmission fluid to leak around gaskets, often visible as drips under the bell housing.
- Abnormal gear engagement noise – A worn housing bore allows the 2095209019: DIFFERENTIAL to shift out of alignment, producing a grinding or whining sound during shifts.
- Recurring bearing failure – Distorted housing pockets prevent the 0750117075: TAPER ROLLER BEARING from seating correctly, leading to premature bearing collapse and shaft play.
- Hydraulic pressure loss – Internal cracks in the housing disrupt oil galleries, causing sluggish clutch engagement or slipping under load.

Compatibility
This transmission housing is designed for ZF WG series powershift transmissions commonly used in wheel loaders, graders, and compactors. Compatible models include WG180, WG200, WG210, and WG250 series. It also fits select ZF 4WG-200 and 6WG-200 variants. Always verify the housing casting number against your transmission serial plate before installation. The housing interfaces directly with the 0631329086: SPRING PIN for dowel alignment and the 5838300817: THRUST WASHER for axial load distribution.
