ZF 2095.056.023 TRA 13 | OEM Genuine Part

Overview

The ZF 2095.056.023 TRA 13 is a genuine OEM transmission component engineered for heavy-duty construction machinery. This precision-machined part sits within the differential assembly of ZF’s modular transmissions, specifically functioning as a critical interface between the axle bevel gear and the differential housing. It manages torque distribution while absorbing axial loads during high-stress operations. The SKU 2095.056.023 is manufactured to ZF’s exacting tolerances, ensuring seamless integration with the 2095109019: DIFFERENTIAL and 2095209037: DIFFERENTIAL assemblies. When paired with the 0750117075: TAPER ROLLER BEARING, this component ensures smooth rotational motion and extended service life in demanding environments like excavators and wheel loaders.

Symptoms of Failure

• Oil leaks near differential housing: Worn seals on the 2095.056.023 cause transmission fluid to seep past the 2095309059: DIFF.HOUSING, leaving puddles under the machine.
• Gear slipping under load: Degraded internal surfaces reduce clamping force, leading to intermittent power loss during digging or lifting operations.
• Metallic grinding noises: Excessive play between this part and the taper roller bearing creates audible chatter, especially during turns.
• Vibration in the drivetrain: Uneven wear on the TRA 13 causes harmonic oscillations that worsen at higher RPMs, indicating imminent failure.

Technical Specifications

Compatibility

This genuine ZF part is designed for the following transmission families used in construction machinery: WG180, WG200, WG211, and WG250 series. It is also compatible with select Ecomat 4 and AS Tronic variants that share the same differential architecture. Always verify your transmission’s serial number against the 2095109019: DIFFERENTIAL mounting pattern before installation.
