ZF 2095.078.006 T 7140 | OEM Genuine Part

Overview

The ZF 2095.078.006 T 7140 is an OEM genuine internal gear and shaft assembly engineered for heavy-duty construction machinery transmissions. This critical component resides within the planetary gear set of ZF power shift transmissions, where it manages torque distribution between the differential and final drive. As a precision-machined part, the SKU 2095.078.006 ensures exact gear mesh alignment and load-bearing capacity, directly influencing machine tractive effort and operational efficiency. It interfaces directly with the 2095109020 DIFFERENTIAL and the 2095209037 DIFFERENTIAL to synchronize wheel speed under varying load conditions.

Symptoms of Failure

• Intermittent gear slipping under load: When the 2095.078.006 wears, the transmission may momentarily lose torque transfer during excavation or grading, causing a noticeable lag in machine response.
• Metallic grinding noise from the transmission housing: Worn teeth or bearing surfaces produce a distinct high-pitched whine or grinding sound, particularly during tight turns or reverse operation.
• Oil contamination with metallic debris: Flakes or fine metal particles in the transmission fluid indicate advanced wear of this gear set, often accompanied by reduced hydraulic pressure.
• Erratic differential lock engagement: A failing gear assembly can cause the 2095309059 DIFF.HOUSING to bind, making differential lock activation inconsistent or noisy.

Technical Specifications

Compatibility

This genuine ZF gear assembly is designed for integration into the following transmission models commonly found in wheel loaders, graders, and telehandlers:

• ZF WG180 series (WG180, WG180/II)
• ZF WG200 series (WG200, WG200/II)
• ZF 4WG-200 powershift transmissions
• ZF 6WG-200 heavy-duty transmissions

Always verify the 0750117075 TAPER ROLLER BEARING condition during replacement, as bearing play directly affects gear alignment.
