Overview
The ZF 2095.078.003 T 7140 is an OEM genuine transmission component engineered for heavy-duty construction machinery. This precision-machined part functions as a critical load-bearing element within the final drive assembly, directly interfacing with the differential housing to manage torque distribution. Specifically, the SKU 2095.078.003 sits between the axle bevel gear and the differential carrier, ensuring rotational stability under extreme loads. When paired with a properly maintained 2095109020 DIFFERENTIAL, this component prevents axial play that would otherwise degrade gear mesh accuracy.
Symptoms of Failure
- Progressive gear whine under load: A high-pitched metallic noise during acceleration signals uneven wear on the 2095.078.003 mating surfaces, often accompanied by vibration in the operator cab.
- Intermittent drive engagement loss: When this part fatigues, operators report momentary power loss during turns, particularly when the 2095209037 DIFFERENTIAL is under asymmetric torque.
- Metallic debris in transmission oil: Flaking material from the 2095.078.003 surface contaminates the lubricant, accelerating wear on the 0750117075 TAPER ROLLER BEARING and adjacent thrust washers.
- Oil seepage at housing seam: Distortion of the part creates micro-gaps, allowing hypoid oil to escape past the 2095309059 DIFF.HOUSING seal interface.

Compatibility
This genuine ZF part is designed for the WG180, WG200, and WG211 series powershift transmissions commonly found in wheel loaders and graders. It also fits select variants of the 4WG-310 and 6WG-260 models where the differential housing uses a 65 mm bearing journal. Always verify the 2095309081 DIFFERENTIAL AXLE spline count matches your assembly before installation.
