Overview
The ZF 2095.058.003 T 7115 L is an OEM genuine gear assembly engineered for the high-torque planetary sections of ZF construction machinery transmissions. This component functions as a critical power transfer element within the final drive cluster, converting rotational force from the countershaft into controlled wheel or track motion. The SKU 2095.058.003 is precision-machined to exact factory tolerances, ensuring seamless meshing with adjacent planetary gears and shafts. When installed, it works in concert with the 5838109006 DIFFERENTIAL to distribute torque evenly across the axle assembly, reducing stress on the drivetrain during heavy loading cycles.
Symptoms of Failure
- Intermittent gear slipping under load – A worn 2095.058.003 often causes momentary loss of drive power when the machine encounters steep grades or heavy bucket loads, a condition frequently searched as “ZF transmission gear slip under load.”
- Metallic grinding noise from the transmission housing – As the gear teeth wear unevenly, a distinct high-pitched whine or grinding sound emerges during acceleration, commonly reported as “ZF final drive grinding noise.”
- Contaminated transmission oil with metallic debris – Flakes of hardened steel in the fluid indicate advanced gear degradation, a symptom mechanics describe as “ZF transmission metal shavings in oil.”
- Reduced top speed and poor hill climbing – The gear’s inability to maintain proper tooth engagement leads to power loss, often flagged in service logs as “ZF construction machine slow uphill.”

Compatibility
This gear assembly is designed for ZF WG180, WG200, and WG250 series transmissions commonly installed in wheel loaders, excavators, and telehandlers. It also fits select models of the ZF T 7115 L final drive unit used in compact construction machinery. For a complete rebuild, pair this gear with the 0750117075 TAPER ROLLER BEARING to support axial loads, and the 2095209037 DIFFERENTIAL for balanced torque distribution. The 2095309059 DIFF.HOUSING provides the necessary enclosure for this gear set, ensuring proper alignment and lubrication flow.
