Overview
The ZF 2095.009.020 T 7117 L is an OEM genuine component engineered for the final drive assembly of heavy-duty construction machinery transmissions. This part functions as a critical interface within the planetary gear set, ensuring precise torque distribution and rotational stability under extreme load conditions. Specifically, it sits within the differential housing where it interacts with the 5838109006 DIFFERENTIAL to manage power transfer from the axle shafts to the wheels. The SKU 2095.009.020 is laser-etched on the component for traceability, guaranteeing it meets ZF’s stringent metallurgical and dimensional standards for off-highway equipment.
Symptoms of Failure
- Oil leaks near the axle flange: When the ZF 2095.009.020 T 7117 L seal surface degrades, hydraulic fluid escapes, leaving visible puddles under the machine after operation.
- Gear slipping during low-speed maneuvering: Worn splines on this part cause intermittent disengagement from the 2095209037 DIFFERENTIAL, resulting in sudden loss of drive torque when turning or climbing.
- Abnormal whining or grinding noises: Excessive play between this component and the 0750117075 TAPER ROLLER BEARING generates metallic chatter, particularly audible at constant speeds above 15 km/h.
- Vibration through the chassis: A fractured 2095.009.020 housing creates imbalance in the rotating assembly, transmitting shudder through the frame during acceleration.

Compatibility
This OEM genuine part is designed for ZF’s WG series powershift transmissions commonly found in wheel loaders, graders, and telehandlers. It directly fits the following transmission models: WG180, WG200, WG210, and WG250. In these assemblies, the 2095.009.020 works in concert with the 2095309059 DIFF.HOUSING to maintain axial alignment. Always verify your transmission serial number before ordering, as minor revisions exist between early and late production units.
