Overview
The ZF 2095.078.001 T 7140 is an OEM genuine transmission component engineered for heavy-duty construction machinery. This precision-machined part integrates directly into the differential housing assembly of ZF powershift transmissions, where it functions as a critical load-bearing element within the final drive system. Specifically, the 2095.078.001 interfaces with the axle bevel gear and differential carrier to manage torque distribution from the transmission output to the wheel ends. As a factory-spec replacement, the SKU 2095.078.001 ensures exact fitment and metallurgical consistency required for sustained operation under high cyclic loads in excavators, wheel loaders, and graders.
Symptoms of Failure
- Low-frequency whining or howling from the axle housing — When the 2095.078.001 wears, gear mesh patterns shift, producing a distinct audible drone that increases with vehicle speed. This often accompanies a failing 2095109020 DIFFERENTIAL.
- Oil seepage around the differential housing flange — Deterioration of the sealing surface on this part allows transmission fluid to escape, leaving visible wet spots on the housing after shutdown.
- Intermittent driveline shudder under load — Worn contact faces cause momentary slip during hard acceleration or climbing, felt as a vibration through the chassis.
- Metallic debris in the transmission oil filter — Advanced wear of the 2095.078.001 sheds ferrous particles, which can be detected during routine oil analysis or filter inspection.

Compatibility
This genuine ZF 2095.078.001 component is designed for use in the following transmission families and final drive assemblies:
- ZF WG180 series (WG180, WG180/II)
- ZF WG200 series (WG200, WG200/II)
