ZF 4108.201.277 HOUSING | OEM Genuine Part

Overview

The ZF 4108.201.277 HOUSING is a critical structural component within the transmission assembly, serving as the primary enclosure that supports the gear train and hydraulic circuits. As an OEM genuine part, this housing ensures precise alignment of internal shafts and bearings, directly influencing torque transfer efficiency. The SKU 4108.201.277 is specifically engineered for heavy-duty construction machinery, where it withstands high cyclic loads and thermal expansion. This housing interfaces directly with the 4108101115 HOUSING to form a sealed unit, while the 0501313402 DRAIN VALVE is mounted to its lower port for fluid evacuation during maintenance.

Symptoms of Failure

• Hydraulic fluid seepage at mating surfaces – Cracks or porosity in the housing cause oil to weep around the 4108306173 GASKET, leading to low fluid levels and erratic shifting.
• Abnormal gear whine or grinding – Distortion of the housing bore misaligns the 4108301304 BEARING COVER, resulting in uneven bearing load and audible noise during acceleration.
• Intermittent power loss under load – Warpage of the housing face reduces clamping force on internal clutches, causing torque converter stall in excavators and loaders.
• Contaminated transmission fluid – Fractures in the housing allow debris ingress, accelerating wear on the 0750110040 SHAFT SEAL and reducing system pressure.

Technical Specifications

Compatibility

This housing is designed for ZF WG series transmissions commonly used in construction machinery. It fits the following models: WG180, WG200, and WG210. These transmissions are found in wheel loaders, telehandlers, and backhoe loaders from manufacturers like Liebherr, Volvo, and JCB. The housing also supports the 4108111051 POWER TAKE-OFF unit for auxiliary hydraulic pumps.
