ZF 2095.209.019 DIFFERENTIAL | OEM Genuine Part

Overview

The ZF 2095.209.019 DIFFERENTIAL is a critical torque-distributing component located within the final drive assembly of heavy-duty construction machinery transmissions. As an OEM genuine part, it ensures that power from the driveline is split evenly between the left and right axle shafts, allowing wheels to rotate at different speeds during cornering while maintaining maximum traction on uneven terrain. The SKU 2095.209.019 is engineered to withstand extreme loads and high-temperature environments typical in wheel loaders, graders, and dozers. This differential works in concert with the 5838109007: DIFFERENTIAL to form the core of the axle assembly, while the 0750117075: TAPER ROLLER BEARING supports its rotational stability.

Symptoms of Failure

• Whining or grinding noise during turns: Worn internal gears within the 2095.209.019 produce a distinct metallic sound when the vehicle corners, indicating excessive clearance or pitting on the spider gears.
• Oil leaks from the axle housing: Degraded seals or a cracked differential case cause gear oil to seep out, often visible as drips near the wheel hub or differential cover.
• Uneven tire wear or wheel hop: A failing differential fails to distribute torque properly, leading to one wheel spinning faster than the other under load, which accelerates tire degradation.
• Clunking on acceleration or deceleration: Excessive backlash from worn gear teeth creates a noticeable thud when power is applied or removed, signaling imminent failure.

Technical Specifications

Compatibility

This differential is designed for ZF WG-series powershift transmissions commonly used in construction machinery. Based on its part type and dimensions, the 2095.209.019 fits the following ZF transmission models: WG180, WG200, WG210, and WG220. It is also found in final drive assemblies for ZF AP400 and ZF AP500 axles. For precise fitment, always verify the original equipment manufacturer (OEM) part number against your machine’s service manual. The 0631329086: SPRING PIN is required to secure the differential cross shaft, while the 5838300817: THRUST WASHER controls axial play within the assembly.
