Overview
The ZF 4108.201.297 HOUSING is a critical structural component within the transmission assembly, serving as the primary enclosure that supports and aligns internal gear sets, shafts, and hydraulic circuits. This OEM genuine part, identified by SKU 4108.201.297, is engineered to withstand high torsional loads and thermal expansion in heavy-duty construction machinery. It integrates directly with the transmission casing to maintain precise tolerances for rotating elements, ensuring efficient power transfer. When paired with the 4108101062 HOUSING, it forms a sealed chamber that protects internal components from debris and contamination.
Symptoms of Failure
- Transmission fluid seepage at casing joints: Cracks or warping in the housing allow oil to escape, often visible as wet spots near the bell housing or mating surfaces.
- Abnormal gear engagement noise: A worn housing can cause misalignment of shafts, leading to grinding or whining sounds during gear shifts under load.
- Intermittent power loss or slipping: Distortion in the housing bore reduces clutch pack pressure, resulting in delayed engagement or torque loss during operation.
- Metal particles in oil filter: Housing degradation may shed microscopic fragments into the lubricant, accelerating wear on bearings and seals.

Compatibility
This housing is designed for ZF WG180, WG200, and WG210 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It is also compatible with select ZF 4WG-200 and 6WG-200 variants. For precise fitment verification, cross-reference the casting number on your existing housing. The 0501215601 OIL LEVEL GAGE and 0501325470 SEALING RING are often replaced simultaneously to prevent leaks. Additionally, the 0730365280 TYPE PLATE should be transferred to the new housing for identification.
