Overview
The ZF 4657.055.117 5 WG 210 Powershift Transmission Assembly | Complete Unit is a fully assembled, ready-to-install gearbox core designed for heavy-duty off-highway machinery. This complete unit integrates the main gear cluster, clutch packs, and hydraulic control system into a single, factory-matched assembly. As the central power transfer module, it sits between the engine and the final drive, managing torque distribution across five forward speeds. The SKU 4657.055.117 is the definitive reference for this specific WG 210 series configuration, ensuring precise replacement without the need for piecemeal component sourcing. For a full rebuild, this assembly is typically mounted within the 4657101082: TRANSMISSION HOUSING and sealed by the 4657201166: HOUS.FRONT SECT.
Symptoms of Failure
When the ZF 4657.055.117 assembly begins to degrade, operators will notice distinct operational issues. Delayed or harsh gear engagement is a primary indicator, often accompanied by a pronounced “clunk” when shifting from neutral to drive. Internal hydraulic pressure loss manifests as slipping under load, particularly when climbing grades or carrying rated payloads. Contaminated transmission fluid showing metallic particles signals internal clutch pack wear. Additionally, erratic shift patterns or failure to reach top gear point to worn valve body components within the unit. Addressing these symptoms early prevents damage to the 4657201170: HOUSING REAR PART and the 4657298102: HOUSING REAR SECTION.
