Overview
The ZF 2095.058.017 T 7117 L is an OEM genuine gear component engineered for the final drive assembly in heavy-duty construction machinery transmissions. This part functions as a critical torque-transfer element within the planetary gear set, ensuring smooth power delivery from the transmission to the axle. As an integral part of the differential housing group, it works in concert with the DIFF.HOUSING (2095309059) to maintain precise gear alignment under extreme loads. The SKU 2095.058.017 is a direct replacement for original ZF factory installations, guaranteeing exact fitment and metallurgical standards for off-highway equipment.
Symptoms of Failure
- Transmission whining or grinding noise during turns: When the gear teeth wear unevenly, audible metal-on-metal contact occurs, particularly at low speeds or under load.
- Oil leaks near the axle flange: A worn ZF 2095.058.017 can cause seal surface degradation, leading to hydraulic fluid seepage around the differential housing.
- Intermittent gear slipping under heavy load: Loss of tooth profile integrity results in momentary power loss when climbing grades or moving dense materials.
- Vibration in the driveline during acceleration: Imbalanced gear rotation from pitting or spalling transmits harmonic vibrations through the chassis.

Compatibility
This OEM genuine part is designed for use in ZF WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, graders, and telehandlers. It also fits select ZF 4WG-200 and ZF 6WG-200 powershift models. For complete differential assembly, pair this gear with the DIFFERENTIAL (2095109016) and the DIFFERENTIAL (2095209037) to restore factory tolerances. The TAPER ROLLER BEARING (0750117075) must be inspected during replacement to prevent premature wear.
