ZF 2095.009.071 T 7120 L | OEM Genuine Part

Overview

The ZF 2095.009.071 T 7120 L is an OEM genuine transmission component engineered for heavy-duty construction machinery. This part functions as a critical internal gear assembly within the ZF power-shift transmission, facilitating torque distribution from the input shaft to the planetary gear sets. Specifically, it manages load transfer during low-range and reverse operations, ensuring smooth engagement under high-stress conditions. The SKU 2095.009.071 is precision-machined to ZF factory tolerances, making it a direct replacement for worn units in wheel loaders, graders, and excavators. When paired with a properly maintained 2095109015 DIFFERENTIAL, this assembly ensures balanced power delivery to the axles, reducing drivetrain vibration and extending service life.

Symptoms of Failure

• Erratic gear engagement under load: When the 2095.009.071 wears, operators may experience delayed or harsh shifting when transitioning from forward to reverse, particularly in stop-and-go loading cycles.
• Metallic grinding noise from transmission housing: Worn teeth on this gear produce a distinct high-pitched whine or grinding sound during low-speed maneuvers, often mistaken for axle bearing failure.
• Oil contamination with metallic debris: A failing unit sheds fine steel particles into the transmission fluid, visible during routine oil changes as glitter-like sediment in the filter.
• Intermittent loss of drive in low gear: The transmission may momentarily slip or fail to hold torque when climbing inclines, indicating that the gear teeth can no longer maintain proper mesh with the mating 0750117075 TAPER ROLLER BEARING.

Technical Specifications

Compatibility

This gear is engineered for ZF T 7120 L series transmissions, commonly installed in construction machinery from 2010 onward. It is directly compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. These transmissions are found in OEM equipment such as Volvo L120/L150 wheel loaders, Caterpillar 950/962 series, and Komatsu WA380/WA480 loaders. For proper installation, verify that the 2095209037 DIFFERENTIAL and 2095309059 DIFF.HOUSING are free from scoring or cracks, as these components work in tandem to maintain gear alignment.
