Overview
The ZF 2095.114.017 CRAWLER is a precision-machined, OEM genuine component engineered for the final drive assembly of heavy-duty construction machinery. This part functions as a critical load-bearing element within the transmission’s planetary gear set, ensuring smooth torque transfer and track alignment under extreme stress. The SKU 2095.114.017 is specifically designed to interface with the differential housing and axle bevel gear, maintaining the structural integrity of the driveline. When paired with a 2095109012: DIFFERENTIAL, this crawler component distributes power evenly to the tracks, reducing vibration and preventing premature wear on adjacent gears.
Symptoms of Failure
When the ZF 2095.114.017 CRAWLER begins to degrade, operators will notice distinct performance issues. Common failure symptoms include:
- Intermittent track slippage under load – The crawler loses grip during excavation or climbing, often misdiagnosed as a hydraulic issue.
- Metallic grinding noises from the final drive – Worn surfaces create a high-pitched whine or chatter, especially during tight turns.
- Oil contamination with metallic debris – Flakes or shavings appear in the transmission fluid, indicating surface fatigue on the crawler’s contact faces.
- Uneven track tension or misalignment – The machine pulls to one side, requiring constant steering correction.

Compatibility
This OEM genuine part is compatible with ZF’s WG180, WG200, and WG211 series transmissions commonly found in crawler dozers, excavators, and track loaders. It directly replaces the original factory component in final drive assemblies for models such as the ZF 4WG-180, 4WG-200, and 6WG-211. For optimal performance, always install this crawler alongside a 0750117075: TAPER ROLLER BEARING and a 2095209037: DIFFERENTIAL to ensure proper axial load distribution. The 2095309059: DIFF.HOUSING must also be inspected for wear during replacement, as housing distortion accelerates crawler failure.
